+# All library objects contain sccsid strings by default; they may be
+# excluded as a space-saving measure.  To produce a library that does
+# not contain these strings, delete -DLIBC_SCCS and -DSYSLIBC_SCCS
+# from CFLAGS below.  To remove these strings from just the system call
+# stubs, remove just -DSYSLIBC_SCCS from CFLAGS.
+#
+# The NLS (message catalog) functions are always in libc.  To choose that
+# strerror(), perror(), strsignal(), psignal(), etc. actually call the NLS
+# functions, put -DNLS on the CFLAGS line below.
+#
+# The YP functions are always in libc. To choose that getpwent() and friends
+# actually call the YP functions, put -DYP on the CFLAGS line below.

+ * Method:

+ * We use the fpu's normalization hardware to compute the integer portion

+ * of word 0.  Thus, values >= 2^52 are by definition integers.
+ *
+ * If we take a value that is in the range [+0..2^52) and add 2^52, all
+ * of the fractional bits fall out and all of the integer bits are summed
+ * with 2^52.  If we then subtract 2^52, we get those integer bits back.
+ * This must be done with rounding set to `towards 0' or `towards -inf'.
+ * `Toward -inf' fails when the value is 0 (we get -0 back)....

+.Fn setregid "int rgid" "int egid"
+.Sh DESCRIPTION
+The real and effective group ID's of the current process
+are set to the arguments.
+Unprivileged users may change the real group
+ID to the effective group ID and vice-versa; only the super-user may
+make other changes.
+.Pp
+Supplying a value of -1 for either the real or effective
+group ID forces the system to substitute the current
+ID in place of the -1 parameter.
+.Pp
+The 
+.Fn setregid
+function was intended to allow swapping the real and
+effective group IDs in set-group-ID programs to temporarily relinquish
+the set-group-ID value.  This function did not work correctly, and its
+purpose is now better served by the use of the
+.Fn setegid
+function (see
+.Xr setuid 2 ).
+.Pp
+When setting the real and effective group IDs to the same value, the
+standard
+.Fn setgid
+function is preferred.
+.Sh RETURN VALUES
+Upon successful completion, a value of 0 is returned.  Otherwise,
+a value of -1 is returned and
+.Va errno
+is set to indicate the error.
+.Sh ERRORS
+.Bl -tag -width Er

+.Fn sigvec "int sig" "struct sigvec *vec" "struct sigvec *ovec"
+.Sh DESCRIPTION
+.Bf -symbolic
+This interface is made obsolete by sigaction(2).
+.Ef
+.Pp
+The system defines a set of signals that may be delivered to a process.
+Signal delivery resembles the occurrence of a hardware interrupt:
+the signal is blocked from further occurrence, the current process 
+context is saved, and a new one is built.  A process may specify a
+.Em handler
+to which a signal is delivered, or specify that a signal is to be 
+.Em blocked
+or
+.Em ignored .
+A process may also specify that a default action is to be taken
+by the system when a signal occurs.
+Normally, signal handlers execute on the current stack
+of the process.  This may be changed, on a per-handler basis,
+so that signals are taken on a special
+.Em "signal stack" .
+.Pp
+All signals have the same
+.Em priority .
+Signal routines execute with the signal that caused their
+invocation
+.Em blocked ,
+but other signals may yet occur.
+A global 
+.Em "signal mask"
+defines the set of signals currently blocked from delivery
+to a process.  The signal mask for a process is initialized
+from that of its parent (normally 0).  It
+may be changed with a
+.Xr sigblock 2
+or
+.Xr sigsetmask 2
+call, or when a signal is delivered to the process.
+.Pp
+When a signal
+condition arises for a process, the signal is added to a set of
+signals pending for the process.  If the signal is not currently
+.Em blocked
+by the process then it is delivered to the process.  When a signal
+is delivered, the current state of the process is saved,
+a new signal mask is calculated (as described below), 
+and the signal handler is invoked.  The call to the handler
+is arranged so that if the signal handling routine returns
+normally the process will resume execution in the context
+from before the signal's delivery.
+If the process wishes to resume in a different context, then it
+must arrange to restore the previous context itself.
+.Pp
+When a signal is delivered to a process a new signal mask is
+installed for the duration of the process' signal handler
+(or until a
+.Xr sigblock
+or
+.Xr sigsetmask
+call is made).
+This mask is formed by taking the current signal mask,
+adding the signal to be delivered, and 
+.Em or Ns 'ing
+in the signal mask associated with the handler to be invoked.
+.Pp
+.Fn Sigvec
+assigns a handler for a specific signal.  If
+.Fa vec
+is non-zero, it
+specifies a handler routine and mask
+to be used when delivering the specified signal.
+Further, if the
+.Dv SV_ONSTACK
+bit is set in
+.Fa sv_flags ,
+the system will deliver the signal to the process on a
+.Em "signal stack" ,
+specified with
+.Xr sigstack 2 .
+If 
+.Fa ovec
+is non-zero, the previous handling information for the signal
+is returned to the user.
+.Pp
+The following is a list of all signals
+with names as in the include file
+.Aq Pa signal.h :
+.Bl -column SIGVTALARMXX "create core imagexxx"

+.El
+.Pp
+Once a signal handler is installed, it remains installed
+until another
+.Fn sigvec
+call is made, or an
+.Xr execve 2
+is performed.
+A signal-specific default action may be reset by
+setting
+.Fa sv_handler
+to
+.Dv SIG_DFL .
+The defaults are process termination, possibly with core dump;
+no action; stopping the process; or continuing the process.
+See the above signal list for each signal's default action.
+If
+.Fa sv_handler
+is
+.Dv SIG_IGN
+current and pending instances
+of the signal are ignored and discarded.
+.Pp
+If a signal is caught during the system calls listed below,
+the call is normally restarted.
+The call can be forced to terminate prematurely with an
+.Dv EINTR
+error return by setting the
+.Dv SV_INTERRUPT
+bit in
+.Fa sv_flags .
+The affected system calls include
+.Xr read 2 ,
+.Xr write 2 ,
+.Xr sendto 2 ,
+.Xr recvfrom 2 ,
+.Xr sendmsg 2
+and
+.Xr recvmsg 2
+on a communications channel or a slow device (such as a terminal,
+but not a regular file)
+and during a
+.Xr wait 2
+or
+.Xr ioctl 2 .
+However, calls that have already committed are not restarted,
+but instead return a partial success (for example, a short read count).
+.Pp
+After a
+.Xr fork 2
+or
+.Xr vfork 2
+all signals, the signal mask, the signal stack,
+and the restart/interrupt flags are inherited by the child.
+.Pp
+.Xr Execve 2
+reinstates the default
+action for all signals which were caught and
+resets all signals to be caught on the user stack.
+Ignored signals remain ignored;
+the signal mask remains the same;
+signals that interrupt system calls continue to do so.
+.Sh NOTES
+The mask specified in 
+.Fa vec
+is not allowed to block
+.Dv SIGKILL
+or
+.Dv SIGSTOP .
+This is done silently by the system.
+.Pp
+The
+.Dv SV_INTERRUPT
+flag is not available in
+.Bx 4.2 ,
+hence it should not be used if backward compatibility is needed.
+.Sh RETURN VALUES
+A 0 value indicated that the call succeeded.  A \-1 return value
+indicates an error occurred and
+.Va errno
+is set to indicated the reason.
+.Sh ERRORS
+.Fn Sigvec
+will fail and no new signal handler will be installed if one
+of the following occurs:
+.Bl -tag -width Er
+.It Bq Er EFAULT
+Either
+.Fa vec
+or 
+.Fa ovec
+points to memory that is not a valid part of the process
+address space.
+.It Bq Er EINVAL
+.Fa Sig
+is not a valid signal number.
+.It Bq Er EINVAL
+An attempt is made to ignore or supply a handler for
+.Dv SIGKILL
+or

+void handler(sig, code, scp)
+int sig, code;
+struct sigcontext *scp;
+.Ed
+.Pp
+Here
+.Fa sig
+is the signal number, into which the hardware faults and traps are
+mapped as defined below. 
+.Fa Code
+is a parameter that is either a constant
+as given below or, for compatibility mode faults, the code provided by
+the hardware (Compatibility mode faults are distinguished from the
+other
+.Dv SIGILL
+traps by having
+.Dv PSL_CM
+set in the psl).
+.Fa Scp
+is a pointer to the
+.Fa sigcontext
+structure (defined in
+.Aq Pa signal.h ) ,
+used to restore the context from before the signal.
+.Sh BUGS
+This manual page is still confusing.

+#	@(#)VERSION	8.17 (Berkeley) 6/20/94
+
+This is version 1.79 of the Berkeley DB code.
+
+For information on compiling and installing this software, see the file
+PORT/README.
+
+If your version of the DB code doesn't have a copy of this version file,
+it's really old, please update it!
+
+Newer versions of this software will periodically be made available by
+anonymous ftp from ftp.cs.berkeley.edu.  An archive in compressed format
+is in ucb/4bsd/db.tar.Z, or in gzip format in ucb/4bsd/db.tar.gz.  If
+you'd like to receive announcements of future releases of this software,
+send email to the contact address below.
+
+Email questions may be addressed to Keith Bostic at bostic@cs.berkeley.edu.
+
+============================================
+Distribution contents:
+
+Makefile.inc	Ignore this, it's the 4.4BSD subsystem Makefile.
+PORT		The per OS/architecture directories to use to build
+		libdb.a, if you're not running 4.4BSD.  See the file
+		PORT/README for more information.
+README		This file.
+VERSION		This file.
+btree		B+tree routines.
+db		Dbopen(3) interface routine.
+doc		USENIX papers, formatted manual pages.
+hash		Extended linear hashing routines.
+man		Unformatted manual pages.
+mpool		Memory pool routines.
+recno		Fixed/variable length record routines.
+test		Test package.
+
+============================================
+1.78 -> 1.79	Mon Jun 20 17:36:47 EDT 1994
+	all:	Minor cleanups of 1.78 for porting reasons; only
+		major change was inlining check of NULL pointer
+		so that __fix_realloc goes away.
+
+1.77 -> 1.78	Thu Jun 16 19:06:43 EDT 1994
+	all:	Move "standard" size typedef's into db.h.
+
+1.76 -> 1.77	Thu Jun 16 16:48:38 EDT 1994
+	hash:	Delete __init_ routine, has special meaning to OSF 2.0.
+
+1.74 -> 1.76
+	all:	Finish up the port to the Alpha.
+
+1.73 -> 1.74
+	recno:	Don't put the record if rec_search fails, in rec_rdelete.
+		Create fixed-length intermediate records past "end" of DB
+		correctly.
+		Realloc bug when reading in fixed records.
+	all:	First cut at port to Alpha (64-bit architecture) using
+		4.4BSD basic integral types typedef's.
+		Cast allocation pointers to shut up old compilers.
+		Rework PORT directory into OS/machine directories.
+
+1.72 -> 1.73
+	btree:	If enough duplicate records were inserted and then deleted
+		that internal pages had references to empty pages of the
+		duplicate keys, the search function ended up on the wrong
+		page.
+
+1.7  -> 1.72	12 Oct 1993
+	hash:	Support NET/2 hash formats.
+
+1.7  -> 1.71	16 Sep 1993
+	btree/recno:
+		Fix bug in internal search routines that caused
+		return of invalid pointers.
+
+1.6  -> 1.7	07 Sep 1993
+	hash:	Fixed big key overflow bugs.
+	test:	Portability hacks, rewrite test script, Makefile.
+	btree/recno:
+		Stop copying non-overflow key/data pairs.
+	PORT:	Break PORT directory up into per architecture/OS
+		subdirectories.
+
+1.5  -> 1.6	06 Jun 1993
+	hash:	In PAIRFITS, the first comparison should look at (P)[2].
+		The hash_realloc function was walking off the end of memory.
+		The overflow page number was wrong when bumping splitpoint.
+
+1.4  -> 1.5	23 May 1993
+	hash:	Set hash default fill factor dynamically.
+	recno:	Fixed bug in sorted page splits.
+		Add page size parameter support.
+		Allow recno to specify the name of the underlying btree;
+			used for vi recovery.
+	btree/recno:
+		Support 64K pages.
+	btree/hash/recno:
+		Provide access to an underlying file descriptor.
+		Change sync routines to take a flag argument, recno
+			uses this to sync out the underlying btree.
+
+1.3  -> 1.4	10 May 1993
+	recno:	Delete the R_CURSORLOG flag from the recno interface.
+		Zero-length record fix for non-mmap reads.
+		Try and make SIZE_T_MAX test in open portable.
+
+1.2  -> 1.3	01 May 1993
+	btree:	Ignore user byte-order setting when reading already
+		existing database.  Fixes to byte-order conversions.
+
+1.1  -> 1.2	15 Apr 1993
+		No bug fixes, only compatibility hacks.

+
+This package implements a superset of the hsearch and dbm/ndbm libraries.
+
+Test Programs:
+	All test programs which need key/data pairs expect them entered
+	with key and data on separate lines
+
+	tcreat3.c	
+		Takes 
+			bucketsize (bsize), 
+			fill factor (ffactor), and
+			initial number of elements (nelem).  
+		Creates a hash table named hashtest containing the 
+		keys/data pairs entered from standard in.
+	thash4.c
+		Takes
+			bucketsize (bsize), 
+			fill factor (ffactor), 
+			initial number of elements (nelem)
+			bytes of cache (ncached), and
+			file from which to read data  (fname)
+		Creates a table from the key/data pairs on standard in and
+		then does a read of each key/data in fname
+	tdel.c
+		Takes
+			bucketsize (bsize), and
+			fill factor (ffactor).
+			file from which to read data (fname)
+		Reads each key/data pair from fname and deletes the
+		key from the hash table hashtest
+	tseq.c
+		Reads the key/data pairs in the file hashtest and writes them
+		to standard out.
+	tread2.c
+		Takes
+			butes of cache (ncached).
+		Reads key/data pairs from standard in and looks them up
+		in the file hashtest.
+	tverify.c
+		Reads key/data pairs from standard in, looks them up
+		in the file hashtest, and verifies that the data is
+		correct.
+
+NOTES:
+
+The file search.h is provided for using the hsearch compatible interface
+on BSD systems.  On System V derived systems, search.h should appear in 
+/usr/include.
+
+The man page ../man/db.3 explains the interface to the hashing system.
+The file hash.ps is a postscript copy of a paper explaining
+the history, implementation, and performance of the hash package.
+
+"bugs" or idiosyncracies
+
+If you have a lot of overflows, it is possible to run out of overflow
+pages.  Currently, this will cause a message to be printed on stderr.
+Eventually, this will be indicated by a return error code.
+
+If you are using the ndbm interface and exit without flushing or closing the
+file, you may lose updates since the package buffers all writes.  Also,
+the db interface only creates a single database file.  To avoid overwriting
+the user's original file, the suffix ".db" is appended to the file name
+passed to dbm_open.  Additionally, if your code "knows" about the historic
+.dir and .pag files, it will break.  
+
+There is a fundamental difference between this package and the old hsearch.
+Hsearch requires the user to maintain the keys and data in the application's
+allocated memory while hash takes care of all storage management.  The down
+side is that the byte strings passed in the ENTRY structure must be null
+terminated (both the keys and the data).

+ *		The format of the page is:
+ *		    KEY_OFF PARTIAL_KEY OVFL_PAGENO OVFLPAGE
+ *		
+ *		    KEY_OFF -- offset of the beginning of the key
+ *		    PARTIAL_KEY -- 1
+ *		    OVFL_PAGENO - page number of the next overflow page
+ *		    OVFLPAGE -- 0

+ *
+ *		Case 1:
+ *		    There is a complete key on the page but no data
+ *		    (because it wouldn't fit).  The next page contains
+ *		    the data.
+ *
+ *		    Page format it:
+ *		    KEY_OFF FULL_KEY OVFL_PAGENO OVFL_PAGE
+ *
+ *		    KEY_OFF -- offset of the beginning of the key
+ *		    FULL_KEY -- 2
+ *		    OVFL_PAGENO - page number of the next overflow page
+ *		    OVFLPAGE -- 0
+ *
+ *		Case 2:
+ *		    This page contains no key, but part of a large
+ *		    data field, which is continued on the next page.
+ *
+ *		    Page format it:
+ *		    DATA_OFF FULL_KEY OVFL_PAGENO OVFL_PAGE
+ *
+ *		    KEY_OFF -- offset of the beginning of the data on
+ *				this page
+ *		    FULL_KEY -- 2
+ *		    OVFL_PAGENO - page number of the next overflow page
+ *		    OVFLPAGE -- 0
+ *
+ * FULL_KEY_DATA 
+ *		This must be the first key/data pair on the page.
+ *		There are two cases:
+ *
+ *		Case 1:
+ *		    This page contains a key and the beginning of the
+ *		    data field, but the data field is continued on the
+ *		    next page.
+ *
+ *		    Page format is:
+ *		    KEY_OFF FULL_KEY_DATA OVFL_PAGENO DATA_OFF
+ *
+ *		    KEY_OFF -- offset of the beginning of the key
+ *		    FULL_KEY_DATA -- 3
+ *		    OVFL_PAGENO - page number of the next overflow page
+ *		    DATA_OFF -- offset of the beginning of the data
+ *
+ *		Case 2:
+ *		    This page contains the last page of a big data pair.
+ *		    There is no key, only the  tail end of the data
+ *		    on this page.
+ *
+ *		    Page format is:
+ *		    DATA_OFF FULL_KEY_DATA <OVFL_PAGENO> <OVFLPAGE>
+ *
+ *		    DATA_OFF -- offset of the beginning of the data on
+ *				this page
+ *		    FULL_KEY_DATA -- 3
+ *		    OVFL_PAGENO - page number of the next overflow page
+ *		    OVFLPAGE -- 0

+.SH NAME
+btree \- btree database access method
+.SH SYNOPSIS
+.nf
+.ft B
+#include <sys/types.h>
+#include <db.h>
+.ft R
+.fi
+.SH DESCRIPTION
+The routine
+.IR dbopen
+is the library interface to database files.
+One of the supported file formats is btree files.
+The general description of the database access methods is in
+.IR dbopen (3),
+this manual page describes only the btree specific information.
+.PP
+The btree data structure is a sorted, balanced tree structure storing
+associated key/data pairs.
+.PP
+The btree access method specific data structure provided to
+.I dbopen
+is defined in the <db.h> include file as follows:
+.PP
+typedef struct {
+.RS
+u_long flags;
+.br
+u_int cachesize;
+.br
+int maxkeypage;
+.br
+int minkeypage;
+.br
+u_int psize;
+.br
+int (*compare)(const DBT *key1, const DBT *key2);
+.br
+size_t (*prefix)(const DBT *key1, const DBT *key2);
+.br
+int lorder;
+.RE
+} BTREEINFO;
+.PP
+The elements of this structure are as follows:
+.TP
+flags
+The flag value is specified by
+.IR or 'ing
+any of the following values:
+.RS
+.TP
+R_DUP
+Permit duplicate keys in the tree, i.e. permit insertion if the key to be
+inserted already exists in the tree.
+The default behavior, as described in
+.IR dbopen (3),
+is to overwrite a matching key when inserting a new key or to fail if
+the R_NOOVERWRITE flag is specified.
+The R_DUP flag is overridden by the R_NOOVERWRITE flag, and if the
+R_NOOVERWRITE flag is specified, attempts to insert duplicate keys into
+the tree will fail.
+.IP
+If the database contains duplicate keys, the order of retrieval of
+key/data pairs is undefined if the
+.I get
+routine is used, however,
+.I seq
+routine calls with the R_CURSOR flag set will always return the logical
+``first'' of any group of duplicate keys.
+.RE
+.TP
+cachesize
+A suggested maximum size (in bytes) of the memory cache.
+This value is
+.B only
+advisory, and the access method will allocate more memory rather than fail.
+Since every search examines the root page of the tree, caching the most
+recently used pages substantially improves access time.
+In addition, physical writes are delayed as long as possible, so a moderate
+cache can reduce the number of I/O operations significantly.
+Obviously, using a cache increases (but only increases) the likelihood of
+corruption or lost data if the system crashes while a tree is being modified.
+If
+.I cachesize
+is 0 (no size is specified) a default cache is used.
+.TP
+maxkeypage
+The maximum number of keys which will be stored on any single page.
+Not currently implemented.
+.\" The maximum number of keys which will be stored on any single page.
+.\" Because of the way the btree data structure works,
+.\" .I maxkeypage
+.\" must always be greater than or equal to 2.
+.\" If
+.\" .I maxkeypage
+.\" is 0 (no maximum number of keys is specified) the page fill factor is
+.\" made as large as possible (which is almost invariably what is wanted).
+.TP
+minkeypage
+The minimum number of keys which will be stored on any single page.
+This value is used to determine which keys will be stored on overflow
+pages, i.e. if a key or data item is longer than the pagesize divided
+by the minkeypage value, it will be stored on overflow pages instead
+of in the page itself.
+If
+.I minkeypage
+is 0 (no minimum number of keys is specified) a value of 2 is used.
+.TP
+psize
+Page size is the size (in bytes) of the pages used for nodes in the tree.
+The minimum page size is 512 bytes and the maximum page size is 64K.
+If
+.I psize
+is 0 (no page size is specified) a page size is chosen based on the
+underlying file system I/O block size.
+.TP
+compare
+Compare is the key comparison function.
+It must return an integer less than, equal to, or greater than zero if the
+first key argument is considered to be respectively less than, equal to,
+or greater than the second key argument.
+The same comparison function must be used on a given tree every time it
+is opened.
+If
+.I compare
+is NULL (no comparison function is specified), the keys are compared
+lexically, with shorter keys considered less than longer keys.
+.TP
+prefix
+Prefix is the prefix comparison function.
+If specified, this routine must return the number of bytes of the second key
+argument which are necessary to determine that it is greater than the first
+key argument.
+If the keys are equal, the key length should be returned.
+Note, the usefulness of this routine is very data dependent, but, in some
+data sets can produce significantly reduced tree sizes and search times.
+If
+.I prefix
+is NULL (no prefix function is specified),
+.B and
+no comparison function is specified, a default lexical comparison routine
+is used.
+If
+.I prefix
+is NULL and a comparison routine is specified, no prefix comparison is
+done.
+.TP
+lorder
+The byte order for integers in the stored database metadata.
+The number should represent the order as an integer; for example, 
+big endian order would be the number 4,321.
+If
+.I lorder
+is 0 (no order is specified) the current host order is used.
+.PP
+If the file already exists (and the O_TRUNC flag is not specified), the
+values specified for the parameters flags, lorder and psize are ignored
+in favor of the values used when the tree was created.
+.PP
+Forward sequential scans of a tree are from the least key to the greatest.
+.PP
+Space freed up by deleting key/data pairs from the tree is never reclaimed,
+although it is normally made available for reuse.
+This means that the btree storage structure is grow-only.
+The only solutions are to avoid excessive deletions, or to create a fresh
+tree periodically from a scan of an existing one.
+.PP
+Searches, insertions, and deletions in a btree will all complete in
+O lg base N where base is the average fill factor.
+Often, inserting ordered data into btrees results in a low fill factor.
+This implementation has been modified to make ordered insertion the best
+case, resulting in a much better than normal page fill factor.

+.SH DESCRIPTION
+.IR Dbopen
+is the library interface to database files.
+The supported file formats are btree, hashed and UNIX file oriented.
+The btree format is a representation of a sorted, balanced tree structure.
+The hashed format is an extensible, dynamic hashing scheme.
+The flat-file format is a byte stream file with fixed or variable length
+records.
+The formats and file format specific information are described in detail
+in their respective manual pages
+.IR btree (3),
+.IR hash (3)
+and
+.IR recno (3).
+.PP
+Dbopen opens
+.I file
+for reading and/or writing.
+Files never intended to be preserved on disk may be created by setting
+the file parameter to NULL.
+.PP
+The
+.I flags
+and
+.I mode arguments
+are as specified to the
+.IR open (2)
+routine, however, only the O_CREAT, O_EXCL, O_EXLOCK, O_NONBLOCK,
+O_RDONLY, O_RDWR, O_SHLOCK and O_TRUNC flags are meaningful.
+(Note, opening a database file O_WRONLY is not possible.)
+.\"Three additional options may be specified by
+.\".IR or 'ing
+.\"them into the
+.\".I flags
+.\"argument.
+.\".TP
+.\"DB_LOCK
+.\"Do the necessary locking in the database to support concurrent access.
+.\"If concurrent access isn't needed or the database is read-only this

+.\".TP
+.\"DB_SHMEM
+.\"Place the underlying memory pool used by the database in shared
+.\"memory.
+.\"Necessary for concurrent access.
+.\".TP
+.\"DB_TXN
+.\"Support transactions in the database.
+.\"The DB_LOCK and DB_SHMEM flags must be set as well.
+.PP
+The
+.I type
+argument is of type DBTYPE (as defined in the <db.h> include file) and
+may be set to DB_BTREE, DB_HASH or DB_RECNO.
+.PP
+The
+.I openinfo
+argument is a pointer to an access method specific structure described
+in the access method's manual page.
+If
+.I openinfo
+is NULL, each access method will use defaults appropriate for the system
+and the access method.
+.PP
+.I Dbopen
+returns a pointer to a DB structure on success and NULL on error.
+The DB structure is defined in the <db.h> include file, and contains at
+least the following fields:
+.sp
+.nf
+typedef struct {
+.RS
+DBTYPE type;
+int (*close)(const DB *db);
+int (*del)(const DB *db, const DBT *key, u_int flags);
+int (*fd)(const DB *db);

+int (*sync)(const DB *db, u_int flags);
+int (*seq)(const DB *db, DBT *key, DBT *data, u_int flags);
+.RE
+} DB;
+.fi
+.PP
+These elements describe a database type and a set of functions performing
+various actions.
+These functions take a pointer to a structure as returned by
+.IR dbopen ,
+and sometimes one or more pointers to key/data structures and a flag value.
+.TP
+type
+The type of the underlying access method (and file format).
+.TP
+close
+A pointer to a routine to flush any cached information to disk, free any
+allocated resources, and close the underlying file(s).
+Since key/data pairs may be cached in memory, failing to sync the file
+with a
+.I close
+or
+.I sync
+function may result in inconsistent or lost information.
+.I Close
+routines return -1 on error (setting
+.IR errno )
+and 0 on success.
+.TP
+del
+A pointer to a routine to remove key/data pairs from the database.
+.IP
+The parameter
+.I flag
+may be set to the following value:
+.RS
+.TP
+R_CURSOR
+Delete the record referenced by the cursor.
+The cursor must have previously been initialized.
+.RE
+.IP
+.I Delete
+routines return -1 on error (setting
+.IR errno ),
+0 on success, and 1 if the specified
+.I key
+was not in the file.
+.TP
+fd
+A pointer to a routine which returns a file descriptor representative
+of the underlying database.
+A file descriptor referencing the same file will be returned to all
+processes which call
+.I dbopen
+with the same
+.I file
+name.
+This file descriptor may be safely used as an argument to the
+.IR fcntl (2)
+and
+.IR flock (2)
+locking functions.
+The file descriptor is not necessarily associated with any of the
+underlying files used by the access method.
+No file descriptor is available for in memory databases.
+.I Fd
+routines return -1 on error (setting
+.IR errno ),
+and the file descriptor on success.
+.TP
+get
+A pointer to a routine which is the interface for keyed retrieval from
+the database.
+The address and length of the data associated with the specified
+.I key
+are returned in the structure referenced by
+.IR data .
+.I Get
+routines return -1 on error (setting
+.IR errno ),
+0 on success, and 1 if the
+.I key
+was not in the file.
+.TP
+put
+A pointer to a routine to store key/data pairs in the database.
+.IP
+The parameter
+.I flag
+may be set to one of the following values:
+.RS
+.TP
+R_CURSOR
+Replace the key/data pair referenced by the cursor.
+The cursor must have previously been initialized.
+.TP
+R_IAFTER
+Append the data immediately after the data referenced by
+.IR key ,
+creating a new key/data pair.
+The record number of the appended key/data pair is returned in the
+.I key
+structure.
+(Applicable only to the DB_RECNO access method.)
+.TP
+R_IBEFORE
+Insert the data immediately before the data referenced by
+.IR key ,
+creating a new key/data pair.
+The record number of the inserted key/data pair is returned in the
+.I key
+structure.
+(Applicable only to the DB_RECNO access method.)
+.TP
+R_NOOVERWRITE
+Enter the new key/data pair only if the key does not previously exist.
+.TP
+R_SETCURSOR
+Store the key/data pair, setting or initializing the position of the
+cursor to reference it.
+(Applicable only to the DB_BTREE and DB_RECNO access methods.)
+.RE
+.IP
+R_SETCURSOR is available only for the DB_BTREE and DB_RECNO access
+methods because it implies that the keys have an inherent order
+which does not change.
+.IP
+R_IAFTER and R_IBEFORE are available only for the DB_RECNO
+access method because they each imply that the access method is able to
+create new keys.
+This is only true if the keys are ordered and independent, record numbers
+for example.
+.IP
+The default behavior of the
+.I put
+routines is to enter the new key/data pair, replacing any previously
+existing key.
+.IP
+.I Put
+routines return -1 on error (setting
+.IR errno ),
+0 on success, and 1 if the R_NOOVERWRITE
+.I flag
+was set and the key already exists in the file.
+.TP
+seq
+A pointer to a routine which is the interface for sequential
+retrieval from the database.
+The address and length of the key are returned in the structure
+referenced by

+Sequential key/data pair retrieval may begin at any time, and the
+position of the ``cursor'' is not affected by calls to the
+.IR del ,

+Modifications to the database during a sequential scan will be reflected
+in the scan, i.e. records inserted behind the cursor will not be returned
+while records inserted in front of the cursor will be returned.
+.IP
+The flag value
+.B must
+be set to one of the following values:
+.RS
+.TP
+R_CURSOR
+The data associated with the specified key is returned.
+This differs from the
+.I get
+routines in that it sets or initializes the cursor to the location of
+the key as well.
+(Note, for the DB_BTREE access method, the returned key is not necessarily an
+exact match for the specified key.
+The returned key is the smallest key greater than or equal to the specified
+key, permitting partial key matches and range searches.)
+.TP
+R_FIRST
+The first key/data pair of the database is returned, and the cursor
+is set or initialized to reference it.
+.TP
+R_LAST
+The last key/data pair of the database is returned, and the cursor
+is set or initialized to reference it.
+(Applicable only to the DB_BTREE and DB_RECNO access methods.)
+.TP
+R_NEXT
+Retrieve the key/data pair immediately after the cursor.
+If the cursor is not yet set, this is the same as the R_FIRST flag.

+(Applicable only to the DB_BTREE and DB_RECNO access methods.)
+.RE
+.IP
+R_LAST and R_PREV are available only for the DB_BTREE and DB_RECNO
+access methods because they each imply that the keys have an inherent

+than the specified or current key.
+If the DB_RECNO access method is being used, and if the database file
+is a character special file and no complete key/data pairs are currently
+available, the

+routines return 2.
+.TP
+sync
+A pointer to a routine to flush any cached information to disk.
+If the database is in memory only, the
+.I sync
+routine has no effect and will always succeed.
+.IP
+The flag value may be set to the following value:
+.RS
+.TP
+R_RECNOSYNC
+If the DB_RECNO access method is being used, this flag causes
+the sync routine to apply to the btree file which underlies the
+recno file, not the recno file itself.

+#include <sys/types.h>
+#include <db.h>
+.ft R
+.fi
+.SH DESCRIPTION
+The routine
+.IR dbopen
+is the library interface to database files.
+One of the supported file formats is hash files.
+The general description of the database access methods is in
+.IR dbopen (3),
+this manual page describes only the hash specific information.
+.PP
+The hash data structure is an extensible, dynamic hashing scheme.
+.PP
+The access method specific data structure provided to
+.I dbopen
+is defined in the <db.h> include file as follows:
+.sp
+typedef struct {
+.RS
+u_int bsize;
+.br
+u_int ffactor;
+.br
+u_int nelem;
+.br
+u_int cachesize;
+.br
+u_int32_t (*hash)(const void *, size_t);
+.br
+int lorder;
+.RE
+} HASHINFO;
+.PP
+The elements of this structure are as follows:
+.TP
+bsize
+.I Bsize
+defines the hash table bucket size, and is, by default, 256 bytes.
+It may be preferable to increase the page size for disk-resident tables
+and tables with large data items.
+.TP
+ffactor
+.I Ffactor
+indicates a desired density within the hash table.
+It is an approximation of the number of keys allowed to accumulate in any
+one bucket, determining when the hash table grows or shrinks.
+The default value is 8.
+.TP
+nelem
+.I Nelem
+is an estimate of the final size of the hash table.
+If not set or set too low, hash tables will expand gracefully as keys
+are entered, although a slight performance degradation may be noticed.
+The default value is 1.
+.TP
+cachesize
+A suggested maximum size, in bytes, of the memory cache.
+This value is
+.B only
+advisory, and the access method will allocate more memory rather
+than fail.
+.TP
+hash
+.I Hash
+is a user defined hash function.
+Since no hash function performs equally well on all possible data, the
+user may find that the built-in hash function does poorly on a particular
+data set.
+User specified hash functions must take two arguments (a pointer to a byte
+string and a length) and return a 32-bit quantity to be used as the hash
+value.
+.TP
+lorder
+The byte order for integers in the stored database metadata.
+The number should represent the order as an integer; for example, 
+big endian order would be the number 4,321.
+If
+.I lorder
+is 0 (no order is specified) the current host order is used.
+If the  file already exists, the specified value is ignored and the
+value specified when the tree was created is used.
+.PP
+If the file already exists (and the O_TRUNC flag is not specified), the
+values specified for the parameters bsize, ffactor, lorder and nelem are
+ignored and the values specified when the tree was created are used.
+.PP
+If a hash function is specified,
+.I hash_open
+will attempt to determine if the hash function specified is the same as
+the one with which the database was created, and will fail if it is not.
+.PP
+Backward compatible interfaces to the routines described in
+.IR dbm (3),
+and
+.IR ndbm (3)
+are provided, however these interfaces are not compatible with
+previous file formats.

+.SH DESCRIPTION
+.IR Mpool
+is the library interface intended to provide page oriented buffer management
+of files.
+The buffers may be shared between processes.
+.PP
+The function
+.I mpool_open
+initializes a memory pool.
+The
+.I key
+argument is the byte string used to negotiate between multiple
+processes wishing to share buffers.
+If the file buffers are mapped in shared memory, all processes using
+the same key will share the buffers.
+If
+.I key
+is NULL, the buffers are mapped into private memory.
+The
+.I fd
+argument is a file descriptor for the underlying file, which must be seekable.
+If
+.I key
+is non-NULL and matches a file already being mapped, the
+.I fd
+argument is ignored.
+.PP
+The
+.I pagesize
+argument is the size, in bytes, of the pages into which the file is broken up.
+The
+.I maxcache
+argument is the maximum number of pages from the underlying file to cache
+at any one time.
+This value is not relative to the number of processes which share a file's
+buffers, but will be the largest value specified by any of the processes
+sharing the file.
+.PP
+The
+.I mpool_filter
+function is intended to make transparent input and output processing of the
+pages possible.
+If the
+.I pgin
+function is specified, it is called each time a buffer is read into the memory
+pool from the backing file.
+If the
+.I pgout
+function is specified, it is called each time a buffer is written into the
+backing file.
+Both functions are are called with the
+.I pgcookie
+pointer, the page number and a pointer to the page to being read or written.
+.PP
+The function
+.I mpool_new
+takes an MPOOL pointer and an address as arguments.
+If a new page can be allocated, a pointer to the page is returned and
+the page number is stored into the
+.I pgnoaddr
+address.
+Otherwise, NULL is returned and errno is set.
+.PP
+The function
+.I mpool_get
+takes a MPOOL pointer and a page number as arguments.
+If the page exists, a pointer to the page is returned.
+Otherwise, NULL is returned and errno is set.
+The flags parameter is not currently used.
+.PP
+The function
+.I mpool_put
+unpins the page referenced by
+.IR pgaddr .
+.I Pgaddr
+must be an address previously returned by
+.I mpool_get
+or
+.IR mpool_new .
+The flag value is specified by
+.IR or 'ing
+any of the following values:
+.TP
+MPOOL_DIRTY
+The page has been modified and needs to be written to the backing file.
+.PP
+.I Mpool_put
+returns 0 on success and -1 if an error occurs.
+.PP
+The function
+.I mpool_sync
+writes all modified pages associated with the MPOOL pointer to the
+backing file.
+.I Mpool_sync
+returns 0 on success and -1 if an error occurs.
+.PP
+The
+.I mpool_close
+function free's up any allocated memory associated with the memory pool
+cookie.
+Modified pages are
+.B not
+written to the backing file.
+.I Mpool_close
+returns 0 on success and -1 if an error occurs.
+.SH ERRORS
+The
+.I mpool_open
+function may fail and set
+.I errno
+for any of the errors specified for the library routine
+.IR malloc (3).

+.SH DESCRIPTION
+The routine
+.IR dbopen
+is the library interface to database files.
+One of the supported file formats is record number files.
+The general description of the database access methods is in
+.IR dbopen (3),
+this manual page describes only the recno specific information.
+.PP
+The record number data structure is either variable or fixed-length
+records stored in a flat-file format, accessed by the logical record
+number.
+The existence of record number five implies the existence of records
+one through four, and the deletion of record number one causes
+record number five to be renumbered to record number four, as well
+as the cursor, if positioned after record number one, to shift down
+one record.
+.PP
+The recno access method specific data structure provided to
+.I dbopen
+is defined in the <db.h> include file as follows:
+.PP
+typedef struct {
+.RS
+u_long flags;
+.br
+u_int cachesize;
+.br
+u_int psize;
+.br
+int lorder;
+.br
+size_t reclen;
+.br
+u_char bval;
+.br
+char *bfname;
+.RE
+} RECNOINFO;
+.PP
+The elements of this structure are defined as follows:
+.TP
+flags
+The flag value is specified by
+.IR or 'ing
+any of the following values:
+.RS
+.TP
+R_FIXEDLEN
+The records are fixed-length, not byte delimited.
+The structure element
+.I reclen
+specifies the length of the record, and the structure element
+.I bval
+is used as the pad character.
+.TP
+R_NOKEY
+In the interface specified by
+.IR dbopen ,
+the sequential record retrieval fills in both the caller's key and
+data structures.
+If the R_NOKEY flag is specified, the
+.I cursor
+routines are not required to fill in the key structure.
+This permits applications to retrieve records at the end of files without
+reading all of the intervening records.
+.TP
+R_SNAPSHOT
+This flag requires that a snapshot of the file be taken when
+.I dbopen
+is called, instead of permitting any unmodified records to be read from
+the original file.
+.RE
+.TP
+cachesize
+A suggested maximum size, in bytes, of the memory cache.
+This value is
+.B only
+advisory, and the access method will allocate more memory rather than fail.
+If
+.I cachesize
+is  0 (no size is specified) a default cache is used.
+.TP
+psize
+The recno access method stores the in-memory copies of its records
+in a btree.
+This value is the size (in bytes) of the pages used for nodes in that tree.
+If
+.I psize
+is 0 (no page size is specified) a page size is chosen based on the
+underlying file system I/O block size.
+See
+.IR btree (3)
+for more information.
+.TP
+lorder
+The byte order for integers in the stored database metadata.
+The number should represent the order as an integer; for example,
+big endian order would be the number 4,321.
+If
+.I lorder
+is 0 (no order is specified) the current host order is used.
+.TP
+reclen
+The length of a fixed-length record.
+.TP
+bval
+The delimiting byte to be used to mark the end of a record for
+variable-length records, and the pad character for fixed-length
+records.
+If no value is specified, newlines (``\en'') are used to mark the end
+of variable-length records and fixed-length records are padded with
+spaces.
+.TP
+bfname
+The recno access method stores the in-memory copies of its records
+in a btree.
+If bfname is non-NULL, it specifies the name of the btree file,
+as if specified as the file name for a dbopen of a btree file.
+.PP
+The data part of the key/data pair used by the recno access method
+is the same as other access methods.
+The key is different.
+The
+.I data
+field of the key should be a pointer to a memory location of type
+.IR recno_t ,
+as defined in the <db.h> include file.
+This type is normally the largest unsigned integral type available to
+the implementation.
+The
+.I size
+field of the key should be the size of that type.
+.PP
+In the interface specified by
+.IR dbopen ,
+using the
+.I put
+interface to create a new record will cause the creation of multiple,
+empty records if the record number is more than one greater than the
+largest record currently in the database.

+.Sh DESCRIPTION
+.Bf -symbolic
+This interface is obsoleted by sysctl(3).
+.Ef
+.Pp
+The
+.Fn confstr
+function provides a method for applications to get configuration
+defined string values.
+.Pp
+The
+.Fa name
+argument specifies the system variable to be queried.
+Symbolic constants for each name value are found in the include file
+.Li <unistd.h> .
+The
+.Fa len
+argument specifies the size of the buffer referenced by the
+argument
+.Fa buf .
+If
+.Fa len
+is non-zero,
+.Fa buf
+is a non-null pointer, and
+.Fa name
+has a value, up to
+.Fa len
+\- 1 bytes of the value are copied into the buffer 
+.Fa buf .
+The copied value is always null terminated.
+.Pp
+The available values are as follows:
+.Pp
+.Bl -tag -width "123456"
+.Pp
+.It Li _CS_PATH
+Return a value for the
+.Ev PATH
+environment variable that finds all the standard utilities.
+.El
+.Sh RETURN VALUES
+If the call to
+.Nm confstr
+is not successful, \-1 is returned and
+.Va errno
+is set appropriately.
+Otherwise, if the variable does not have a configuration defined value,
+0 is returned and
+.Va errno
+is not modified.
+Otherwise, the buffer size needed to hold the entire configuration-defined
+value is returned.
+If this size is greater than the argument
+.Fa len ,
+the string in
+.Fa buf
+was truncated.
+.Sh ERRORS
+The
+.Nm confstr
+function may fail and set
+.Va error
+for any of the errors specified for the library functions
+.Xr malloc 3
+and
+.Xr sysctl 3 .
+.Pp
+In addition, the following errors may be reported:
+.Bl -tag -width Er
+.It Bq Er EINVAL
+The value of the
+.Fa name

+.Sh SEE ALSO
+.Xr sysctl 3
+.Sh HISTORY
+The

+.Sh NAME

+.Nd generate terminal pathname
+.Sh SYNOPSIS
+.Fd #include <stdio.h>
+.Ft char *
+.Fn ctermid "char *buf"
+.Sh DESCRIPTION
+The
+.Fn ctermid
+function generates a string, that, when used as a pathname, refers to
+the current controlling terminal of the calling process.
+.Pp
+If
+.Ar buf
+is the
+.Dv NULL
+pointer, a pointer to a static area is returned.
+Otherwise, the pathname is copied into the memory referenced by
+.Ar buf .
+The argument
+.Ar buf
+is assumed to point to an array at least
+.Dv L_ctermid
+(as defined in the include
+file
+.Aq Pa stdio.h )
+bytes long.
+.Pp
+The current implementation simply returns
+.Ql /dev/tty .
+.Sh RETURN VALUES
+Upon successful completion, a
+.Pf non- Dv NULL
+pointer is returned.
+Otherwise, a
+.Dv NULL
+pointer is returned and the global variable
+.Va errno
+is set to indicate the error.
+.Sh ERRORS
+The current implementation detects no error conditions.
+.Sh SEE ALSO
+.Xr ttyname 3
+.Sh STANDARDS
+The
+.Xr ctermid
+function conforms to
+.St -p1003.1-88 .
+.Sh BUGS
+By default the
+.Fn ctermid
+function
+writes all information to an internal static object.
+Subsequent calls to
+.Fn ctermid
+will modify the same object.

+.Ft int
+.Fn closedir "DIR *dirp"
+.Ft int
+.Fn dirfd "DIR *dirp"
+.Sh DESCRIPTION
+The
+.Fn opendir
+function
+opens the directory named by
+.Fa filename ,
+associates a
+.Em directory stream
+with it
+and
+returns a pointer to be used to identify the
+.Em directory stream
+in subsequent operations.  The pointer
+.Dv NULL
+is returned if
+.Fa filename
+cannot be accessed, or if it cannot
+.Xr malloc 3
+enough memory to hold the whole thing.
+.Pp
+The
+.Fn readdir
+function
+returns a pointer to the next directory entry.  It returns
+.Dv NULL
+upon reaching the end of the directory or detecting an invalid
+.Fn seekdir
+operation.
+.Pp
+The
+.Fn telldir
+function
+returns the current location associated with the named
+.Em directory stream .
+.Pp
+The
+.Fn seekdir
+function
+sets the position of the next
+.Fn readdir
+operation on the
+.Em directory stream .
+The new position reverts to the one associated with the
+.Em directory stream
+when the
+.Fn telldir
+operation was performed.  Values returned by
+.Fn telldir
+are good only for the lifetime of the
+.Dv DIR
+pointer,
+.Fa dirp ,
+from which they are derived.
+If the directory is closed and then reopened, the 
+.Fn telldir
+value may be invalidated due to undetected directory compaction.
+It is safe to use a previous
+.Fn telldir
+value immediately after a call to
+.Fn opendir
+and before any calls to
+.Fn readdir .
+.Pp
+The
+.Fn rewinddir
+function
+resets the position of the named
+.Em directory stream
+to the beginning of the directory.
+.Pp
+The
+.Fn closedir
+function
+closes the named
+.Em directory stream
+and frees the structure associated with the
+.Fa dirp
+pointer,
+returning 0 on success.
+On failure, \-1 is returned and the global variable
+.Va errno
+is set to indicate the error.
+.Pp
+The
+.Fn dirfd
+function
+returns the integer file descriptor associated with the named
+.Em directory stream ,
+see
+.Xr open 2 .
+.Pp
+Sample code which searchs a directory for entry ``name'' is:
+.Bd -literal -offset indent
+len = strlen(name);
+dirp = opendir(".");
+while ((dp = readdir(dirp)) != NULL)
+	if (dp->d_namlen == len && !strcmp(dp->d_name, name)) {
+		(void)closedir(dirp);
+		return FOUND;
+	}
+(void)closedir(dirp);
+return NOT_FOUND;

+.Sh DESCRIPTION
+The
+.Nm exec
+family of functions replaces the current process image with a
+new process image.
+The functions described in this manual page are front-ends for the function
+.Xr execve 2 .
+(See the manual page for
+.Xr execve
+for detailed information about the replacement of the current process.)
+.Pp
+The initial argument for these functions is the pathname of a file which
+is to be executed.
+.Pp
+The
+.Fa "const char *arg"
+and subsequent ellipses in the
+.Fn execl ,
+.Fn execlp ,
+and
+.Fn execle
+functions can be thought of as
+.Em arg0 ,
+.Em arg1 ,
+\&...,
+.Em argn .
+Together they describe a list of one or more pointers to null-terminated
+strings that represent the argument list available to the executed program.
+The first argument, by convention, should point to the file name associated
+with the file being executed.
+The list of arguments
+.Em must
+be terminated by a
+.Dv NULL
+pointer.
+.Pp
+The
+.Fn exect ,
+.Fn execv ,
+and
+.Fn execvp
+functions provide an array of pointers to null-terminated strings that
+represent the argument list available to the new program.
+The first argument, by convention, should point to the file name associated
+with the file begin executed.
+The array of pointers
+.Sy must
+be terminated by a
+.Dv NULL
+pointer.
+.Pp
+The
+.Fn execle
+and
+.Fn exect
+functions also specify the environment of the executed process by following
+the
+.Dv NULL
+pointer that terminates the list of arguments in the parameter list
+or the pointer to the argv array with an additional parameter.
+This additional parameter is an array of pointers to null-terminated strings
+and
+.Em must
+be terminated by a
+.Dv NULL
+pointer.
+The other functions take the environment for the new process image from the
+external variable
+.Va environ
+in the current process.
+.Pp
+Some of these functions have special semantics.
+.Pp
+The functions
+.Fn execlp
+and
+.Fn execvp
+will duplicate the actions of the shell in searching for an executable file
+if the specified file name does not contain a slash
+.Dq Li /
+character.
+The search path is the path specified in the environment by
+.Dq Ev PATH
+variable.
+If this variable isn't specified, the default path
+.Dq Ev /bin:/usr/bin:
+is
+used.
+In addition, certain errors are treated specially.
+.Pp
+If permission is denied for a file (the attempted
+.Xr execve
+returned
+.Er EACCES ) ,
+these functions will continue searching the rest of
+the search path.
+If no other file is found, however, they will return with the global variable
+.Va errno
+set to
+.Er EACCES .
+.Pp
+If the header of a file isn't recognized (the attempted
+.Xr execve
+returned
+.Er ENOEXEC ) ,
+these functions will execute the shell with the path of
+the file as its first argument.
+(If this attempt fails, no further searching is done.)
+.Pp
+If the file is currently busy (the attempted
+.Xr execve
+returned
+.Er ETXTBUSY ) ,
+these functions will sleep for several seconds,
+periodically re-attempting to execute the file.
+.Pp
+The function
+.Fn exect
+executes a file with the program tracing facilities enabled (see
+.Xr ptrace 2 ) .
+.Sh RETURN VALUES
+If any of the
+.Xr exec
+functions returns, an error will have occurred.
+The return value is \-1, and the global variable
+.Va errno
+will be set to indicate the error.
+.Sh FILES
+.Bl -tag -width /bin/sh -compact
+.It Pa /bin/sh
+The shell.
+.El
+.Sh ERRORS
+.Fn Execl ,
+.Fn execle ,
+.Fn execlp
+and
+.Fn execvp
+may fail and set
+.Va errno
+for any of the errors specified for the library functions
+.Xr execve 2
+and
+.Xr malloc 3 .
+.Pp
+.Fn Exect
+and
+.Fn execv
+may fail and set
+.Va errno
+for any of the errors specified for the library function
+.Xr execve 2 .
+.Sh SEE ALSO
+.Xr sh 1 ,
+.Xr execve 2 ,
+.Xr fork 2 ,
+.Xr trace 2 ,
+.Xr environ 7 ,
+.Xr ptrace 2 ,
+.Xr environ 7 ,
+.Sh COMPATIBILITY
+Historically, the default path for the
+.Fn execlp
+and
+.Fn execvp
+functions was
+.Dq Pa :/bin:/usr/bin .
+This was changed to place the current directory last to enhance system
+security.
+.Pp
+The behavior of
+.Fn execlp
+and
+.Fn execvp
+when errors occur while attempting to execute the file is historic
+practice, but has not traditionally been documented and is not specified
+by the
+.Tn POSIX
+standard.
+.Pp
+Traditionally, the functions
+.Fn execlp
+and
+.Fn execvp
+ignored all errors except for the ones described above and
+.Er ENOMEM
+and
+.Er E2BIG ,
+upon which they returned.
+They now return if any error other than the ones described above occurs.
+.Sh STANDARDS
+.Fn Execl ,
+.Fn execv ,
+.Fn execle ,
+.Fn execlp
+and
+.Fn execvp
+conform to
+.St -p1003.1-88 .

+.Sh NAME
+.Nm fnmatch
+.Nd match filename or pathname
+.Sh SYNOPSIS
+.Fd #include <fnmatch.h>
+.Ft int
+.Fn fnmatch "const char *pattern" "const char *string" "int flags"
+.Sh DESCRIPTION
+The
+.Fn fnmatch
+function
+matches patterns according to the rules used by the shell.
+It checks the string specified by the
+.Fa string
+argument to see if it matches the pattern specified by the
+.Fa pattern
+argument.
+.Pp
+The
+.Fa flags
+argument modifies the interpretation of
+.Fa pattern
+and
+.Fa string .
+The value of
+.Fa flags
+is the bitwise inclusive
+.Tn OR
+of any of the following
+constants, which are defined in the include file
+.Pa fnmatch.h .
+.Bl -tag -width FNM_PATHNAME
+.It Dv FNM_NOESCAPE
+Normally, every occurrence of a backslash
+.Pq Ql \e
+followed by a character in
+.Fa pattern
+is replaced by that character.
+This is done to negate any special meaning for the character.
+If the
+.Dv FNM_NOESCAPE
+flag is set, a backslash character is treated as an ordinary character.
+.It Dv FNM_PATHNAME
+Slash characters in
+.Fa string
+must be explicitly matched by slashes in
+.Fa pattern .
+If this flag is not set, then slashes are treated as regular characters.
+.It Dv FNM_PERIOD
+Leading periods in strings match periods in patterns.
+The definition of ``leading'' is related to the specification of
+.Dv FNM_PATHNAME.
+A period is always ``leading'' if it is the first character in
+.Ar string .
+Additionally, if
+.Dv FNM_PATHNAME
+is set,
+a period is ``leading'' if it immediately follows a slash.
+.El
+.Sh RETURN VALUES
+The
+.Fn fnmatch
+function returns zero if
+.Fa string
+matches the pattern specified by
+.Fa pattern ,
+otherwise, it returns the value
+.Dv FNM_NOMATCH .
+.Sh SEE ALSO
+.Xr sh 1 ,
+.Xr glob 3 ,
+.Xr regex 3
+.Sh STANDARDS
+The
+.Fn fnmatch
+function conforms to
+.St -p1003.2-92 .
+.Sh HISTORY
+The
+.Fn fnmatch
+function first appeared in 
+.Bx 4.4 .
+.Sh BUGS
+The pattern
+.Ql *
+matches the empty string, even if
+.Dv FNM_PATHNAME
+is specified.

+.Sh SYNOPSIS
+.Fd #include <sys/types.h>
+.Fd #include <sys/ipc.h>
+.Ft key_t
+.Fn ftok "const char *path" "char id" ;
+.Sh DESCRIPTION
+The
+.Fn ftok
+function attempts to create a unique key suitable for use with the
+.Xr msgget 2 ,
+.Xr semget 2
+and
+.Xr shmget 2
+functions given the
+.Fa path
+of an existing file and a user-selectable
+.Fa id .
+.Pp
+The specified
+.Fa path
+must specify an existing file that is accessible to the calling process
+or the call will fail.  Also, note that links to files will return the
+same key, given the same
+.Fa id .
+.Sh RETURN VALUES
+The
+.Fn ftok
+function will return -1 if
+.Fa path
+does not exist or if it cannot be accessed by the calling process.
+.Sh SEE ALSO
+.Xr msgget 2 ,
+.Xr semget 2 ,
+.Xr shmget 2
+.Sh HISTORY
+The
+.Fn ftok
+function originate with System V and is typically used by programs
+that use the System V IPC routines.
+.Sh AUTHOR
+.Bl -tag
+Thorsten Lockert <tholo@sigmasoft.com>
+.El
+.Sh BUGS
+The returned key is computed based on the device and inode of the
+specified
+.Fa path
+in combination with the given
+.Fa id .
+Thus is is quite possible for the routine to return duplicate keys
+given that those fields are not 8- and 16-bit quantities like they
+were on System V based systems where this library routine's ancestor
+were originally created.

+.Ft int
+.Fn fts_close "FTS *ftsp"
+.Sh DESCRIPTION
+The
+.Nm fts
+functions are provided for traversing
+.Tn UNIX
+file hierarchies.
+A simple overview is that the
+.Fn fts_open
+function returns a ``handle'' on a file hierarchy, which is then supplied to
+the other
+.Nm fts
+functions.
+The function
+.Fn fts_read
+returns a pointer to a structure describing one of the files in the file
+hierarchy.
+The function
+.Fn fts_children
+returns a pointer to a linked list of structures, each of which describes
+one of the files contained in a directory in the hierarchy.
+In general, directories are visited two distinguishable times; in pre-order
+(before any of their descendants are visited) and in post-order (after all
+of their descendants have been visited).
+Files are visited once.
+It is possible to walk the hierarchy ``logically'' (ignoring symbolic links)
+or physically (visiting symbolic links), order the walk of the hierarchy or
+prune and/or re-visit portions of the hierarchy.
+.Pp
+Two structures are defined (and typedef'd) in the include file
+.Aq Pa fts.h .
+The first is
+.Fa FTS ,
+the structure that represents the file hierarchy itself.
+The second is
+.Fa FTSENT ,
+the structure that represents a file in the file
+hierarchy.
+Normally, an
+.Fa FTSENT
+structure is returned for every file in the file
+hierarchy.
+In this manual page, ``file'' and
+.Dq Fa FTSENT No structure
+are generally
+interchangeable.
+The
+.Fa FTSENT
+structure contains at least the following fields, which are
+described in greater detail below:
+.Bd -literal
+typedef struct _ftsent {
+	u_short fts_info;		/* flags for FTSENT structure */
+	char *fts_accpath;		/* access path */
+	char *fts_path;			/* root path */
+	short fts_pathlen;		/* strlen(fts_path) */
+	char *fts_name;			/* file name */
+	short fts_namelen;		/* strlen(fts_name) */
+	short fts_level;		/* depth (\-1 to N) */
+	int fts_errno;			/* file errno */
+	long fts_number;		/* local numeric value */
+	void *fts_pointer;		/* local address value */
+	struct ftsent *fts_parent;	/* parent directory */
+	struct ftsent *fts_link;	/* next file structure */
+	struct ftsent *fts_cycle;	/* cycle structure */
+	struct stat *fts_statp;		/* stat(2) information */
+} FTSENT;
+.Ed
+.Pp
+These fields are defined as follows:
+.Bl -tag -width "fts_namelen"
+.It Fa fts_info
+One of the following flags describing the returned
+.Fa FTSENT
+structure and
+the file it represents.
+With the exception of directories without errors
+.Pq Dv FTS_D ,
+all of these
+entries are terminal, that is, they will not be revisited, nor will any
+of their descendants be visited.
+.Bl  -tag -width FTS_DEFAULT
+.It Dv FTS_D
+A directory being visited in pre-order.
+.It Dv FTS_DC
+A directory that causes a cycle in the tree.
+(The
+.Fa fts_cycle
+field of the
+.Fa FTSENT
+structure will be filled in as well.)
+.It Dv FTS_DEFAULT
+Any
+.Fa FTSENT
+structure that represents a file type not explicitly described
+by one of the other
+.Fa fts_info
+values.
+.It Dv FTS_DNR
+A directory which cannot be read.
+This is an error return, and the
+.Fa fts_errno
+field will be set to indicate what caused the error.
+.It Dv FTS_DOT
+A file named
+.Ql \&.
+or
+.Ql ..
+which was not specified as a file name to
+.Fn fts_open
+(see
+.Dv FTS_SEEDOT ) .
+.It Dv FTS_DP
+A directory being visited in post-order.
+The contents of the
+.Fa FTSENT
+structure will be unchanged from when
+it was returned in pre-order, i.e. with the
+.Fa fts_info
+field set to
+.Dv FTS_D .
+.It Dv FTS_ERR
+This is an error return, and the
+.Fa fts_errno
+field will be set to indicate what caused the error.
+.It Dv FTS_F
+A regular file.
+.It Dv FTS_NS
+A file for which no
+.Xr stat 2
+information was available.
+The contents of the
+.Fa fts_statp
+field are undefined.
+This is an error return, and the
+.Fa fts_errno
+field will be set to indicate what caused the error.
+.It Dv FTS_NSOK
+A file for which no
+.Xr stat 2
+information was requested.
+The contents of the
+.Fa fts_statp
+field are undefined.
+.It Dv FTS_SL
+A symbolic link.
+.It Dv FTS_SLNONE
+A symbolic link with a non-existent target.
+The contents of the
+.Fa fts_statp
+field reference the file characteristic information for the symbolic link
+itself.
+.El
+.It Fa fts_accpath
+A path for accessing the file from the current directory.
+.It Fa fts_path
+The path for the file relative to the root of the traversal.
+This path contains the path specified to
+.Fn fts_open
+as a prefix.
+.It Fa fts_pathlen
+The length of the string referenced by
+.Fa fts_path .
+.It Fa fts_name
+The name of the file.
+.It Fa fts_namelen
+The length of the string referenced by
+.Fa fts_name .
+.It Fa fts_level
+The depth of the traversal, numbered from \-1 to N, where this file
+was found.
+The
+.Fa FTSENT
+structure representing the parent of the starting point (or root)
+of the traversal is numbered \-1, and the
+.Fa FTSENT
+structure for the root
+itself is numbered 0.
+.It Fa fts_errno
+Upon return of a
+.Fa FTSENT
+structure from the
+.Fn fts_children
+or
+.Fn fts_read
+functions, with its
+.Fa fts_info
+field set to 
+.Dv FTS_DNR ,
+.Dv FTS_ERR
+or
+.Dv FTS_NS ,
+the
+.Fa fts_errno
+field contains the value of the external variable
+.Va errno
+specifying the cause of the error.
+Otherwise, the contents of the
+.Fa fts_errno
+field are undefined.
+.It Fa fts_number
+This field is provided for the use of the application program and is
+not modified by the
+.Nm fts
+functions.
+It is initialized to 0.
+.It Fa fts_pointer
+This field is provided for the use of the application program and is
+not modified by the
+.Nm fts
+functions.
+It is initialized to
+.Dv NULL .
+.It Fa fts_parent
+A pointer to the
+.Fa FTSENT
+structure referencing the file in the hierarchy
+immediately above the current file, i.e. the directory of which this
+file is a member.
+A parent structure for the initial entry point is provided as well,
+however, only the
+.Fa fts_level ,
+.Fa fts_number
+and
+.Fa fts_pointer
+fields are guaranteed to be initialized.
+.It Fa fts_link
+Upon return from the
+.Fn fts_children
+function, the
+.Fa fts_link
+field points to the next structure in the NULL-terminated linked list of
+directory members.
+Otherwise, the contents of the
+.Fa fts_link
+field are undefined.
+.It Fa fts_cycle
+If a directory causes a cycle in the hierarchy (see
+.Dv FTS_DC ) ,
+either because
+of a hard link between two directories, or a symbolic link pointing to a
+directory, the
+.Fa fts_cycle
+field of the structure will point to the
+.Fa FTSENT
+structure in the hierarchy that references the same file as the current
+.Fa FTSENT
+structure.
+Otherwise, the contents of the
+.Fa fts_cycle
+field are undefined.
+.It Fa fts_statp
+A pointer to
+.Xr stat 2
+information for the file.
+.El
+.Pp
+A single buffer is used for all of the paths of all of the files in the
+file hierarchy.
+Therefore, the
+.Fa fts_path
+and
+.Fa fts_accpath
+fields are guaranteed to be
+.Dv NULL Ns -terminated
+.Em only
+for the file most recently returned by
+.Fn fts_read .
+To use these fields to reference any files represented by other
+.Fa FTSENT
+structures will require that the path buffer be modified using the
+information contained in that
+.Fa FTSENT
+structure's
+.Fa fts_pathlen
+field.
+Any such modifications should be undone before further calls to
+.Fn fts_read
+are attempted.
+The
+.Fa fts_name
+field is always
+.Dv NULL Ns -terminated.
+.Sh FTS_OPEN
+The
+.Fn fts_open
+function takes a pointer to an array of character pointers naming one
+or more paths which make up a logical file hierarchy to be traversed.
+The array must be terminated by a
+.Dv NULL
+pointer.
+.Pp
+There are
+a number of options, at least one of which (either
+.Dv FTS_LOGICAL
+or
+.Dv FTS_PHYSICAL )
+must be specified.
+The options are selected by
+.Em or Ns 'ing
+the following values:
+.Bl -tag -width "FTS_PHYSICAL"
+.It Dv FTS_COMFOLLOW
+This option causes any symbolic link specified as a root path to be
+followed immediately whether or not
+.Dv FTS_LOGICAL
+is also specified.
+.It Dv FTS_LOGICAL
+This option causes the
+.Nm fts
+routines to return
+.Fa FTSENT
+structures for the targets of symbolic links
+instead of the symbolic links themselves.
+If this option is set, the only symbolic links for which
+.Fa FTSENT
+structures
+are returned to the application are those referencing non-existent files.
+Either
+.Dv FTS_LOGICAL
+or
+.Dv FTS_PHYSICAL
+.Em must
+be provided to the
+.Fn fts_open
+function.
+.It Dv FTS_NOCHDIR
+As a performance optimization, the
+.Nm fts
+functions change directories as they walk the file hierarchy.
+This has the side-effect that an application cannot rely on being
+in any particular directory during the traversal.
+The
+.Dv FTS_NOCHDIR
+option turns off this optimization, and the
+.Nm fts
+functions will not change the current directory.
+Note that applications should not themselves change their current directory
+and try to access files unless
+.Dv FTS_NOCHDIR
+is specified and absolute
+pathnames were provided as arguments to
+.Fn fts_open .
+.It Dv FTS_NOSTAT
+By default, returned
+.Fa FTSENT
+structures reference file characteristic information (the
+.Fa statp
+field) for each file visited.
+This option relaxes that requirement as a performance optimization,
+allowing the
+.Nm fts
+functions to set the
+.Fa fts_info
+field to
+.Dv FTS_NSOK
+and leave the contents of the
+.Fa statp
+field undefined.
+.It Dv FTS_PHYSICAL
+This option causes the
+.Nm fts
+routines to return
+.Fa FTSENT
+structures for symbolic links themselves instead
+of the target files they point to.
+If this option is set,
+.Fa FTSENT
+structures for all symbolic links in the
+hierarchy are returned to the application.
+Either
+.Dv FTS_LOGICAL
+or
+.Dv FTS_PHYSICAL
+.Em must
+be provided to the
+.Fn fts_open
+function.
+.It Dv FTS_SEEDOT
+By default, unless they are specified as path arguments to
+.Fn fts_open ,
+any files named
+.Ql \&.
+or
+.Ql ..
+encountered in the file hierarchy are ignored.
+This option causes the
+.Nm fts
+routines to return
+.Fa FTSENT
+structures for them.
+.It Dv FTS_XDEV
+This option prevents
+.Nm fts
+from descending into directories that have a different device number
+than the file from which the descent began.
+.El
+.Pp
+The argument
+.Fn compar
+specifies a user-defined function which may be used to order the traversal
+of the hierarchy.
+It
+takes two pointers to pointers to
+.Fa FTSENT
+structures as arguments and
+should return a negative value, zero, or a positive value to indicate
+if the file referenced by its first argument comes before, in any order
+with respect to, or after, the file referenced by its second argument.
+The
+.Fa fts_accpath ,
+.Fa fts_path
+and
+.Fa fts_pathlen
+fields of the
+.Fa FTSENT
+structures may
+.Em never
+be used in this comparison.
+If the 
+.Fa fts_info
+field is set to
+.Dv FTS_NS
+or
+.Dv FTS_NSOK ,
+the
+.Fa fts_statp
+field may not either.
+If the
+.Fn compar
+argument is
+.Dv NULL ,
+the directory traversal order is in the order listed in
+.Fa path_argv
+for the root paths, and in the order listed in the directory for
+everything else.
+.Sh FTS_READ
+The
+.Fn fts_read
+function returns a pointer to an
+.Fa FTSENT
+structure describing a file in
+the hierarchy.
+Directories (that are readable and do not cause cycles) are visited at
+least twice, once in pre-order and once in post-order.
+All other files are visited at least once.
+(Hard links between directories that do not cause cycles or symbolic
+links to symbolic links may cause files to be visited more than once,
+or directories more than twice.)
+.Pp
+If all the members of the hierarchy have been returned,
+.Fn fts_read
+returns
+.Dv NULL
+and sets the external variable
+.Va errno
+to 0.
+If an error unrelated to a file in the hierarchy occurs,
+.Fn fts_read
+returns
+.Dv NULL
+and sets
+.Va errno
+appropriately.
+If an error related to a returned file occurs, a pointer to an
+.Fa FTSENT
+structure is returned, and
+.Va errno
+may or may not have been set (see
+.Fa fts_info ) .
+.Pp
+The
+.Fa FTSENT
+structures returned by
+.Fn fts_read
+may be overwritten after a call to
+.Fn fts_close
+on the same file hierarchy stream, or, after a call to
+.Fn fts_read
+on the same file hierarchy stream unless they represent a file of type
+directory, in which case they will not be overwritten until after a call to
+.Fn fts_read
+after the
+.Fa FTSENT
+structure has been returned by the function
+.Fn fts_read
+in post-order.
+.Sh FTS_CHILDREN
+The
+.Fn fts_children
+function returns a pointer to an
+.Fa FTSENT
+structure describing the first entry in a NULL-terminated linked list of
+the files in the directory represented by the
+.Fa FTSENT
+structure most recently returned by
+.Fn fts_read .
+The list is linked through the
+.Fa fts_link
+field of the
+.Fa FTSENT
+structure, and is ordered by the user-specified comparison function, if any.
+Repeated calls to
+.Fn fts_children
+will recreate this linked list.
+.Pp
+As a special case, if
+.Fn fts_read
+has not yet been called for a hierarchy,
+.Fn fts_children
+will return a pointer to the files in the logical directory specified to
+.Fn fts_open ,
+i.e. the arguments specified to
+.Fn fts_open .
+Otherwise, if the
+.Fa FTSENT
+structure most recently returned by
+.Fn fts_read
+is not a directory being visited in pre-order,
+or the directory does not contain any files,
+.Fn fts_children
+returns
+.Dv NULL
+and sets
+.Va errno
+to zero.
+If an error occurs,
+.Fn fts_children
+returns
+.Dv NULL
+and sets
+.Va errno
+appropriately.
+.Pp
+The
+.Fa FTSENT
+structures returned by
+.Fn fts_children
+may be overwritten after a call to
+.Fn fts_children ,
+.Fn fts_close
+or
+.Fn fts_read
+on the same file hierarchy stream.
+.Pp
+.Em Option
+may be set to the following value:
+.Bl -tag -width FTS_NAMEONLY
+.It Dv FTS_NAMEONLY
+Only the names of the files are needed.
+The contents of all the fields in the returned linked list of structures
+are undefined with the exception of the
+.Fa fts_name
+and
+.Fa fts_namelen
+fields.
+.El
+.Sh FTS_SET
+The function
+.Fn fts_set
+allows the user application to determine further processing for the
+file
+.Fa f
+of the stream
+.Fa ftsp .
+The
+.Fn fts_set
+function
+returns 0 on success, and \-1 if an error occurs.
+.Em Option
+must be set to one of the following values:
+.Bl -tag -width FTS_PHYSICAL
+.It Dv FTS_AGAIN
+Re-visit the file; any file type may be re-visited.
+The next call to
+.Fn fts_read
+will return the referenced file.
+The
+.Fa fts_stat
+and
+.Fa fts_info
+fields of the structure will be reinitialized at that time,
+but no other fields will have been changed.
+This option is meaningful only for the most recently returned
+file from
+.Fn fts_read .
+Normal use is for post-order directory visits, where it causes the
+directory to be re-visited (in both pre and post-order) as well as all
+of its descendants.
+.It Dv FTS_FOLLOW
+The referenced file must be a symbolic link.
+If the referenced file is the one most recently returned by
+.Fn fts_read ,
+the next call to
+.Fn fts_read
+returns the file with the
+.Fa fts_info
+and
+.Fa fts_statp
+fields reinitialized to reflect the target of the symbolic link instead
+of the symbolic link itself.
+If the file is one of those most recently returned by
+.Fn fts_children ,
+the
+.Fa fts_info
+and
+.Fa fts_statp
+fields of the structure, when returned by
+.Fn fts_read ,
+will reflect the target of the symbolic link instead of the symbolic link
+itself.
+In either case, if the target of the symbolic link does not exist the
+fields of the returned structure will be unchanged and the
+.Fa fts_info
+field will be set to
+.Dv FTS_SLNONE .
+.Pp
+If the target of the link is a directory, the pre-order return, followed
+by the return of all of its descendants, followed by a post-order return,
+is done.
+.It Dv FTS_SKIP
+No descendants of this file are visited.
+The file may be one of those most recently returned by either
+.Fn fts_children
+or
+.Fn fts_read .
+.El
+.Sh FTS_CLOSE
+The
+.Fn fts_close
+function closes a file hierarchy stream
+.Fa ftsp
+and restores the current directory to the directory from which
+.Fn fts_open
+was called to open
+.Fa ftsp .
+The
+.Fn fts_close
+function
+returns 0 on success, and \-1 if an error occurs.
+.Sh ERRORS
+The function
+.Fn fts_open
+may fail and set
+.Va errno
+for any of the errors specified for the library functions
+.Xr open 2
+and
+.Xr malloc 3 .
+.Pp

+.Nd get user block size
+.Sh SYNOPSIS
+.Fd #include <stdlib.h>
+.Ft char *
+.Fn getbsize "int *headerlenp" "long *blocksizep"
+.Sh DESCRIPTION
+The
+.Nm getbsize
+function determines the user's preferred block size based on the value of the
+.Dq BLOCKSIZE
+environment variable; see
+.Xr environ 7
+for details on its use and format.
+.Pp
+The
+.Nm getbsize
+function returns a pointer to a null-terminated string describing
+the block size, something like
+.Dq 1K-blocks .
+The memory referenced by
+.Fa headerlenp
+is filled in with the length of the string (not including the
+terminating null).
+The memory referenced by
+.Fa blocksizep
+is filled in with block size, in bytes.
+.Pp
+If the user's block size is unreasonable, a warning message is
+written to standard error and the returned information reflects
+a block size of 512 bytes.
+.Sh SEE ALSO
+.Xr df 1 ,

+.Sh DESCRIPTION
+.Fn Cgetent
+extracts the capability rec
+.Fa name
+from the database specified by the
+.Dv NULL
+terminated file array
+.Fa db_array
+and returns a pointer to a
+.Xr malloc Ns \&'d
+copy of it in
+.Fa buf .  
+.Nm Cgetent
+will first look for files ending in 
+.Nm .db 
+(see
+.Xr cap_mkdb 1) 
+before accessing the ASCII file.
+.Fa Buf
+must be retained through all subsequent calls to
+.Fn cgetmatch ,
+.Fn cgetcap ,
+.Fn cgetnum ,
+.Fn cgetstr ,
+and
+.Fn cgetustr ,
+but may then be
+.Xr free Ns \&'d.
+On success 0 is returned, 1 if the returned
+record contains an unresolved 
+.Nm tc 
+expansion,
+\-1 if the requested record couldn't be found,
+\-2 if a system error was encountered (couldn't open/read a file, etc.) also
+setting
+.Va errno , 
+and \-3 if a potential reference loop is detected (see
+.Ic tc=
+comments below).
+.Pp
+.Nm Cgetset 
+enables the addition of a character buffer containing a single capability
+record entry
+to the capability database.  
+Conceptually, the entry is added as the first ``file'' in the database, and
+is therefore searched first on the call to 
+.Nm cgetent .
+The entry is passed in 
+.Fa ent .
+If 
+.Fa ent 
+is
+.Dv NULL ,
+the current entry is removed from the database.  
+.Nm Cgetset 
+must precede the database traversal.  It must be called before the 
+.Nm cgetent 
+call. If a sequential access is being performed (see below), it must be called
+before the first sequential access call (
+.Nm cgetfirst
+or
+.Nm cgetnext
+), or be directly preceded by a 
+.Nm cgetclose
+call.
+On success 0 is returned and \-1 on failure.
+.Pp
+.Nm Cgetmatch
+will return 0 if
+.Fa name
+is one of the names of the capability record
+.Fa buf ,
+\-1 if
+not.
+.Pp
+.Nm Cgetcap
+searches the capability record
+.Fa buf
+for the capability
+.Fa cap
+with type
+.Fa type .
+A
+.Fa type
+is specified using any single character.  If a colon (`:') is used, an
+untyped capability will be searched for (see below for explanation of
+types).  A pointer to the value of
+.Fa cap
+in
+.Fa buf
+is returned on success,
+.Dv NULL
+if the requested capability couldn't be
+found.  The end of the capability value is signaled by a `:' or
+.Tn ASCII
+.Dv NUL
+(see below for capability database syntax).
+.Pp
+.Nm Cgetnum
+retrieves the value of the numeric capability
+.Fa cap
+from the capability record pointed to by
+.Fa buf .
+The numeric value is returned in the
+.Ft long
+pointed to by
+.Fa num .
+0 is returned on success, \-1 if the requested numeric capability couldn't
+be found.
+.Pp
+.Nm Cgetstr
+retrieves the value of the string capability
+.Fa cap
+from the capability record pointed to by
+.Fa buf .
+A pointer to a decoded,
+.Dv NUL
+terminated,
+.Xr malloc Ns \&'d
+copy of the string is returned in the
+.Ft char *
+pointed to by
+.Fa str .
+The number of characters in the decoded string not including the trailing
+.Dv NUL
+is returned on success, \-1 if the requested string capability couldn't
+be found, \-2 if a system error was encountered (storage allocation
+failure).
+.Pp
+.Nm Cgetustr
+is identical to 
+.Nm cgetstr 
+except that it does not expand special characters, but rather returns each
+character of the capability string literally.
+.Pp
+.Nm Cgetfirst ,
+.Nm cgetnext , 
+comprise a function group that provides for sequential
+access of the
+.Dv NULL
+pointer terminated array of file names,
+.Fa db_array .
+.Nm Cgetfirst 
+returns the first record in the database and resets the access
+to the first record.
+.Nm Cgetnext 
+returns the next record in the database with respect to the
+record returned by the previous
+.Nm cgetfirst
+or
+.Nm cgetnext 
+call.  If there is no such previous call, the first record in the database is
+returned.
+Each record is returned in a
+.Xr malloc Ns \&'d 
+copy pointed to by 
+.Fa buf .  
+.Ic Tc
+expansion is done (see
+.Ic tc= 
+comments below).
+Upon completion of the database 0 is returned,  1 is returned upon successful
+return of record with possibly more remaining (we haven't reached the end of 
+the database yet), 2 is returned if the record contains an unresolved
+.Nm tc 
+expansion, \-1 is returned if an system error occurred, and \-2
+is returned if a potential reference loop is detected (see 
+.Ic tc=
+comments below).
+Upon completion of database (0 return) the database is closed.
+.Pp
+.Nm Cgetclose 
+closes the sequential access and frees any memory and file descriptors 
+being used.  Note that it does not erase the buffer pushed by a call to 
+.Nm cgetset .
+.Sh CAPABILITY DATABASE SYNTAX
+Capability databases are normally
+.Tn ASCII
+and may be edited with standard
+text editors.  Blank lines and lines beginning with a `#' are comments
+and are ignored.  Lines ending with a `\|\e' indicate that the next line
+is a continuation of the current line; the `\|\e' and following newline
+are ignored.  Long lines are usually continued onto several physical
+lines by ending each line except the last with a `\|\e'.
+.Pp
+Capability databases consist of a series of records, one per logical
+line.  Each record contains a variable number of `:'-separated fields
+(capabilities).  Empty fields consisting entirely of white space
+characters (spaces and tabs) are ignored.
+.Pp
+The first capability of each record specifies its names, separated by `|'
+characters.  These names are used to reference records in the database.
+By convention, the last name is usually a comment and is not intended as
+a lookup tag.  For example, the
+.Em vt100
+record from the
+.Nm termcap
+database begins:
+.Pp
+.Dl "d0\||\|vt100\||\|vt100-am\||\|vt100am\||\|dec vt100:"
+.Pp
+giving four names that can be used to access the record.
+.Pp
+The remaining non-empty capabilities describe a set of (name, value)
+bindings, consisting of a names optionally followed by a typed values:
+.Bl -column "nameTvalue"
+.It name Ta "typeless [boolean] capability"
+.Em name No "is present [true]"
+.It name Ns Em \&T Ns value Ta capability
+.Pq Em name , \&T
+has value
+.Em value
+.It name@ Ta "no capability" Em name No exists
+.It name Ns Em T Ns \&@ Ta capability
+.Pq Em name , T
+does not exist
+.El
+.Pp
+Names consist of one or more characters.  Names may contain any character
+except `:', but it's usually best to restrict them to the printable
+characters and avoid use of graphics like `#', `=', `%', `@', etc.  Types
+are single characters used to separate capability names from their
+associated typed values.  Types may be any character except a `:'.
+Typically, graphics like `#', `=', `%', etc. are used.  Values may be any
+number of characters and may contain any character except `:'.
+.Sh CAPABILITY DATABASE SEMANTICS
+Capability records describe a set of (name, value) bindings.  Names may
+have multiple values bound to them.  Different values for a name are
+distinguished by their
+.Fa types .
+.Nm Cgetcap
+will return a pointer to a value of a name given the capability name and
+the type of the value.
+.Pp
+The types `#' and `=' are conventionally used to denote numeric and
+string typed values, but no restriction on those types is enforced.  The
+functions
+.Nm cgetnum
+and
+.Nm cgetstr
+can be used to implement the traditional syntax and semantics of `#'
+and `='.
+Typeless capabilities are typically used to denote boolean objects with
+presence or absence indicating truth and false values respectively.
+This interpretation is conveniently represented by:
+.Pp
+.Dl "(getcap(buf, name, ':') != NULL)"
+.Pp
+A special capability,
+.Ic tc= name ,
+is used to indicate that the record specified by
+.Fa name
+should be substituted for the
+.Ic tc
+capability.
+.Ic Tc
+capabilities may interpolate records which also contain
+.Ic tc
+capabilities and more than one
+.Ic tc
+capability may be used in a record.  A
+.Ic tc
+expansion scope (i.e., where the argument is searched for) contains the
+file in which the
+.Ic tc
+is declared and all subsequent files in the file array.
+.Pp
+When a database is searched for a capability record, the first matching
+record in the search is returned.  When a record is scanned for a
+capability, the first matching capability is returned; the capability
+.Ic :nameT@:
+will hide any following definition of a value of type
+.Em T
+for
+.Fa name ;
+and the capability
+.Ic :name@:
+will prevent any following values of
+.Fa name
+from being seen.
+.Pp
+These features combined with
+.Ic tc
+capabilities can be used to generate variations of other databases and
+records by either adding new capabilities, overriding definitions with new
+definitions, or hiding following definitions via `@' capabilities.
+.Sh EXAMPLES
+.Bd -unfilled -offset indent
+example\||\|an example of binding multiple values to names:\e
+	:foo%bar:foo^blah:foo@:\e
+	:abc%xyz:abc^frap:abc$@:\e
+	:tc=more:
+.Ed
+.Pp
+The capability foo has two values bound to it (bar of type `%' and blah of
+type `^') and any other value bindings are hidden.  The capability abc
+also has two values bound but only a value of type `$' is prevented from
+being defined in the capability record more.
+.Pp
+.Bd -unfilled -offset indent
+file1:
+ 	new\||\|new_record\||\|a modification of "old":\e
+		:fript=bar:who-cares@:tc=old:blah:tc=extensions:
+file2:
+	old\||\|old_record\||\|an old database record:\e
+		:fript=foo:who-cares:glork#200:
+.Ed
+.Pp
+The records are extracted by calling
+.Nm cgetent
+with file1 preceding file2.
+In the capability record new in file1, fript=bar overrides the definition
+of fript=foo interpolated from the capability record old in file2,
+who-cares@ prevents the definition of any who-cares definitions in old
+from being seen, glork#200 is inherited from old, and blah and anything
+defined by the record extensions is added to those definitions in old.
+Note that the position of the fript=bar and who-cares@ definitions before
+tc=old is important here.  If they were after, the definitions in old
+would take precedence.
+.Sh CGETNUM AND CGETSTR SYNTAX AND SEMANTICS
+Two types are predefined by
+.Nm cgetnum
+and
+.Nm cgetstr :
+.Bl -column "nameXnumber"
+.Sm off
+.It Em name No \&# Em number Ta numeric
+capability
+.Em name
+has value
+.Em number
+.It Em name No = Em string Ta "string capability"
+.Em name
+has value 
+.Em string
+.It Em name No \&#@ Ta "the numeric capability"
+.Em name
+does not exist
+.It Em name No \&=@ Ta "the string capability"
+.Em name
+does not exist
+.El
+.Pp
+Numeric capability values may be given in one of three numeric bases.
+If the number starts with either
+.Ql 0x
+or
+.Ql 0X
+it is interpreted as a hexadecimal number (both upper and lower case a-f
+may be used to denote the extended hexadecimal digits).
+Otherwise, if the number starts with a
+.Ql 0
+it is interpreted as an octal number.
+Otherwise the number is interpreted as a decimal number.
+.Pp
+String capability values may contain any character.  Non-printable
+.Dv ASCII
+codes, new lines, and colons may be conveniently represented by the use
+of escape sequences:
+.Bl -column "\e\|X,X\e\|X" "(ASCII octal nnn)"
+^X	('\fIX\fP' & 037)	control-\fIX\fP
+\e\|b, \e\|B	(ASCII 010)	backspace
+\e\|t, \e\|T	(ASCII 011)	tab
+\e\|n, \e\|N	(ASCII 012)	line feed (newline)
+\e\|f, \e\|F	(ASCII 014)	form feed
+\e\|r, \e\|R	(ASCII 015)	carriage return
+\e\|e, \e\|E	(ASCII 027)	escape
+\e\|c, \e\|C	(:)	colon
+\e\|\e	(\e\|)	back slash
+\e\|^	(^)	caret
+\e\|\fInnn\fP	(ASCII octal \fInnn\fP)
+.El
+.Pp
+A `\|\e' may be followed by up to three octal digits directly specifies
+the numeric code for a character.  The use of
+.Tn ASCII
+.Dv NUL Ns s ,
+while easily
+encoded, causes all sorts of problems and must be used with care since
+.Dv NUL Ns s
+are typically used to denote the end of strings; many applications
+use `\e\|200' to represent a
+.Dv NUL .
+.Sh DIAGNOSTICS

+.Sh BUGS
+Colons (`:') can't be used in names, types, or values.
+.Pp
+There are no checks for
+.Ic tc= name

+.Dt GETCWD 3
+.Os BSD 4.2
+.Sh NAME
+.Nm getcwd ,
+.Nm getwd
+.Nd get working directory pathname
+.Sh SYNOPSIS
+.Fd #include <unistd.h>
+.Ft char *
+.Fn getcwd "char *buf" "size_t size"
+.Ft char *
+.Fn getwd "char *buf"
+.Sh DESCRIPTION
+The
+.Fn getcwd
+function copies the absolute pathname of the current working directory
+into the memory referenced by
+.Fa buf
+and returns a pointer to
+.Fa buf .
+The
+.Fa size
+argument is the size, in bytes, of the array referenced by
+.Fa buf .
+.Pp
+If
+.Fa buf
+is
+.Dv NULL ,
+space is allocated as necessary to store the pathname.
+This space may later be
+.Xr free 3 Ns 'd.
+.Pp
+The function
+.Fn getwd
+is a compatibility routine which calls
+.Fn getcwd
+with its
+.Fa buf
+argument and a size of
+.Dv MAXPATHLEN
+(as defined in the include
+file
+.Aq Pa sys/param.h ) .
+Obviously,
+.Fa buf
+should be at least
+.Dv MAXPATHLEN
+bytes in length.
+.Pp
+These routines have traditionally been used by programs to save the
+name of a working directory for the purpose of returning to it.
+A much faster and less error-prone method of accomplishing this is to
+open the current directory
+.Pq Ql \&.
+and use the
+.Xr fchdir 2
+function to return.
+.Sh RETURN VALUES
+Upon successful completion, a pointer to the pathname is returned.
+Otherwise a
+.Dv NULL
+pointer is returned and the global variable
+.Va errno
+is set to indicate the error.
+In addition,
+.Fn getwd
+copies the error message associated with
+.Va errno
+into the memory referenced by
+.Fa buf .
+.Sh ERRORS
+The
+.Fn getcwd
+function
+will fail if:
+.Bl -tag -width Er
+.It Bq Er EACCESS
+Read or search permission was denied for a component of the pathname.
+.It Bq Er EINVAL
+The
+.Fa size
+argument is zero.
+.It Bq Er ENOENT
+A component of the pathname no longer exists.
+.It Bq Er ENOMEM
+Insufficient memory is available.
+.It Bq Er ERANGE
+The
+.Fa size
+argument is greater than zero but smaller than the length of the pathname
+plus 1.
+.El
+.Sh SEE ALSO
+.Xr chdir 2 ,
+.Xr fchdir 2 ,
+.Xr malloc 3 ,
+.Xr strerror 3
+.Sh STANDARDS
+The
+.Fn getcwd
+function
+conforms to
+.St -ansiC .
+The ability to specify a
+.Dv NULL
+pointer and have
+.Fn getcwd
+allocate memory as necessary is an extension.
+.Sh HISTORY
+The
+.Fn getwd
+function appeared in 
+.Bx 4.0 .
+.Sh BUGS
+The
+.Fn getwd
+function
+does not do sufficient error checking and is not able to return very
+long, but valid, paths.
+It is provided for compatibility.

+.Sh DESCRIPTION
+These functions operate on the group database file
+.Pa /etc/group
+which is described
+in
+.Xr group 5 .
+Each line of the database is defined by the structure
+.Ar group
+found in the include
+file
+.Aq Pa grp.h :
+.Bd -literal -offset indent
+struct group {
+	char	*gr_name;	/* group name */
+	char	*gr_passwd;	/* group password */
+	gid_t	gr_gid;		/* group id */
+	char	**gr_mem;	/* group members */
+};
+.Ed
+.Pp
+The functions
+.Fn getgrnam
+and
+.Fn getgrgid
+search the group database for the given group name pointed to by
+.Ar name
+or the group id pointed to by
+.Ar gid ,
+respectively, returning the first one encountered.  Identical group
+names or group gids may result in undefined behavior.
+.Pp
+The
+.Fn getgrent
+function
+sequentially reads the group database and is intended for programs
+that wish to step through the complete list of groups.
+.Pp
+All three routines will open the group file for reading, if necessary.
+.Pp
+The
+.Fn setgroupent
+function
+opens the file, or rewinds it if it is already open.  If
+.Fa stayopen
+is non-zero, file descriptors are left open, significantly speeding
+functions subsequent calls.  This functionality is unnecessary for
+.Fn getgrent
+as it doesn't close its file descriptors by default.  It should also
+be noted that it is dangerous for long-running programs to use this
+functionality as the group file may be updated.
+.Pp
+The
+.Fn setgrent
+function
+is equivalent to
+.Fn setgroupent
+with an argument of zero.
+.Pp
+The
+.Fn endgrent
+function
+closes any open files.
+.Sh RETURN VALUES
+The functions
+.Fn getgrent ,
+.Fn getgrnam ,
+and
+.Fn getgrgid ,
+return a pointer to the group entry if successful; if end-of-file
+is reached or an error occurs a null pointer is returned.
+The
+.Fn setgroupent
+function returns the value 1 if successful, otherwise the value
+0 is returned.
+The 
+.Fn endgrent
+and
+.Fn setgrent
+functions have no return value.
+.Sh FILES
+.Bl -tag -width /etc/group -compact

+.Sh HISTORY
+The functions
+.Fn endgrent ,
+.Fn getgrent ,
+.Fn getgrnam ,
+.Fn getgrgid ,
+and
+.Fn setgrent
+appeared in
+.At v7 .
+The functions
+.Fn setgrfile
+and
+.Fn setgroupent
+appeared in
+.Bx 4.3 Reno .
+.Sh COMPATIBILITY
+The historic function
+.Fn setgrfile ,
+which allowed the specification of alternate password databases, has
+been deprecated and is no longer available.
+.Sh BUGS
+The functions
+.Fn getgrent ,
+.Fn getgrnam ,
+.Fn getgrgid ,
+.Fn setgroupent
+and
+.Fn setgrent
+leave their results in an internal static object and return
+a pointer to that object. Subsequent calls to
+the same function
+will modify the same object.
+.Pp
+The functions
+.Fn getgrent ,
+.Fn endgrent ,
+.Fn setgroupent ,
+and
+.Fn setgrent
+are fairly useless in a networked environment and should be
+avoided, if possible.

+The
+.Fn getgrouplist
+function reads through the group file and calculates
+the group access list for the user specified in
+.Fa name .
+The
+.Fa basegid
+is automatically included in the groups list.
+Typically this value is given as
+the group number from the password file.

+The resulting group list is returned in the integer array pointed to by
+.Fa groups .
+The caller specifies the size of the 
+.Fa groups
+array in the integer pointed to by
+.Fa ngroups ;
+the actual number of groups found is returned in
+.Fa ngroups .
+.Sh RETURN VALUES
+The
+.Fn getgrouplist
+function
+returns \-1 if the size of the group list is too small to
+hold all the user's groups.
+Here, the group array will be filled with as many groups as will fit.

+.Os
+.Sh NAME
+.Nm getnetgrent ,
+.Nm innetgr ,
+.Nm setnetgrent ,
+.Nm endnetgrent
+.Nd netgroup database operations
+.Sh SYNOPSIS
+.Ft int
+.Fn getnetgrent "char **host, char **user, char **domain"
+.Ft int
+.Fn innetgr "const char *netgroup, const char *host, const char *user, const char *domain"
+.Ft void
+.Fn setnetgrent "const char *netgroup"
+.Ft void
+.Fn endnetgrent void
+.Sh DESCRIPTION
+These functions operate on the netgroup database file
+.Pa /etc/netgroup.db
+which is described
+in
+.Xr netgroup 5 .
+If that file does not exist, and the system supports 
+.Sy YP,
+then the
+.Sy netgroup 
+.Sy YP
+databases are used instead.
+The database defines a set of netgroups, each made up of one or more triples:
+.Bd -literal -offset indent
+(host, user, domain)
+.Ed
+.Pp
+that defines a combination of host, user and domain.
+Any of the three fields may be specified as ``wildcards'' that match any
+string.
+.Pp
+The function
+.Fn getnetgrent
+sets the three pointer arguments to the strings of the next member of the
+current netgroup.
+If any of the string pointers are
+.Sy (char *)0
+that field is considered a wildcard.
+.Pp
+The functions
+.Fn setnetgrent
+and
+.Fn endnetgrent
+set the current netgroup and terminate the current netgroup respectively.
+If
+.Fn setnetgrent
+is called with a different netgroup than the previous call, an implicit
+.Fn endnetgrent
+is implied.
+.Fn Setnetgrent
+also sets the offset to the first member of the netgroup.
+.Pp
+The function
+.Fn innetgr
+searches for a match of all fields within the specified group.
+If any of the
+.Sy host ,
+.Sy user ,
+or
+.Sy domain
+arguments are
+.Sy (char *)0
+those fields will match any string value in the netgroup member.
+.Sh RETURN VALUES
+The function
+.Fn getnetgrent
+returns 0 for ``no more netgroup members'' and 1 otherwise.
+The function
+.Fn innetgr
+returns 1 for a successful match and 0 otherwise.
+The functions
+.Fn setnetgrent
+and
+.Fn endnetgrent
+have no return value.
+.Sh FILES
+.Bl -tag -width /etc/netgroup -compact
+.It Pa /etc/netgroup
+netgroup database file
+.El
+.Sh SEE ALSO
+.Fn netgroup 5
+.Sh BUGS
+The function
+.Fn getnetgrent
+returns pointers to dynamically allocated data areas that are free'd when
+the function
+.Fn endnetgrent
+is called.

+.Sh DESCRIPTION
+These functions
+operate on the password database file
+which is described
+in
+.Xr passwd 5 .
+Each entry in the database is defined by the structure
+.Ar passwd
+found in the include
+file
+.Aq Pa pwd.h :
+.Bd -literal -offset indent
+struct passwd {
+	char	*pw_name;	/* user name */

+};
+.Ed
+.Pp
+The functions
+.Fn getpwnam
+and
+.Fn getpwuid
+search the password database for the given login name or user uid,
+respectively, always returning the first one encountered.
+.Pp
+The
+.Fn getpwent
+function
+sequentially reads the password database and is intended for programs
+that wish to process the complete list of users.
+.Pp
+The
+.Fn setpassent
+function
+accomplishes two purposes.
+First, it causes
+.Fn getpwent
+to ``rewind'' to the beginning of the database.
+Additionally, if
+.Fa stayopen
+is non-zero, file descriptors are left open, significantly speeding
+up subsequent accesses for all of the routines.
+(This latter functionality is unnecessary for
+.Fn getpwent
+as it doesn't close its file descriptors by default.)
+.Pp
+It is dangerous for long-running programs to keep the file descriptors
+open as the database will become out of date if it is updated while the
+program is running.
+.Pp
+The
+.Fn setpwent
+function
+is equivalent to
+.Fn setpassent
+with an argument of zero.
+.Pp
+The
+.Fn endpwent
+function
+closes any open files.
+.Pp
+These routines have been written to ``shadow'' the password file, e.g.
+allow only certain programs to have access to the encrypted password.
+If the process which calls them has an effective uid of 0, the encrypted
+password will be returned, otherwise, the password field of the returned
+structure will point to the string
+.Ql * .
+.Sh RETURN VALUES
+The functions
+.Fn getpwent ,
+.Fn getpwnam ,
+and
+.Fn getpwuid ,
+return a valid pointer to a passwd structure on success
+and a null pointer if end-of-file is reached or an error occurs.
+The
+.Fn setpassent
+function returns 0 on failure and 1 on success.
+The
+.Fn endpwent
+and 
+.Fn setpwent
+functions
+have no return value.

+The
+.Nm setpassent
+function appeared in
+.Bx 4.3 Reno .
+.Sh BUGS
+The functions
+.Fn getpwent ,
+.Fn getpwnam ,
+and
+.Fn getpwuid ,
+leave their results in an internal static object and return
+a pointer to that object. Subsequent calls to
+the same function
+will modify the same object.
+.Pp
+The routines
+.Fn getpwent ,
+.Fn endpwent ,
+.Fn setpassent ,
+and
+.Fn setpwent
+are fairly useless in a networked environment and should be
+avoided, if possible.
+.Sh COMPATIBILITY
+The historic function
+.Xr setpwfile 3 ,
+which allowed the specification of alternate password databases,
+has been deprecated and is no longer available.

+.Ft int
+.Fn getsubopt "char **optionp" "char * const *tokens" "char **valuep"
+.Sh DESCRIPTION
+The
+.Fn getsubopt
+parses a string containing tokens delimited by one or more tab, space or
+comma
+.Pq Ql \&,
+characters.
+It is intended for use in parsing groups of option arguments provided
+as part of a utility command line.
+.Pp
+The argument
+.Fa optionp
+is a pointer to a pointer to the string.
+The argument
+.Fa tokens
+is a pointer to a
+.Dv NULL Ns -terminated
+array of pointers to strings.
+.Pp
+The
+.Fn getsubopt
+function
+returns the zero-based offset of the pointer in the
+.Fa tokens
+array referencing a string which matches the first token
+in the string, or, \-1 if the string contains no tokens or
+.Fa tokens
+does not contain a matching string.
+.Pp
+If the token is of the form ``name=value'', the location referenced by
+.Fa valuep
+will be set to point to the start of the ``value'' portion of the token.
+.Pp
+On return from
+.Fn getsubopt ,
+.Fa optionp
+will be set to point to the start of the next token in the string,
+or the null at the end of the string if no more tokens are present.
+The external variable
+.Fa suboptarg
+will be set to point to the start of the current token, or
+.Dv NULL
+if no
+tokens were present.
+The argument
+.Fa valuep
+will be set to point to the ``value'' portion of the token, or
+.Dv NULL
+if no ``value'' portion was present.

+.It Dv TTY_LOCAL
+If the terminal port's driver supports it, cause the line
+to be treated as ``local.''
+.It Dv TTY_RTSCTS
+If the terminal port's driver supports it, use
+full-duplex RTS/CTS hardware flow control on the line
+by default.
+.It Dv TTY_SOFTCAR
+If the terminal port's driver supports it, ignore hardware
+carrier on the line.
+.El
+.It Fa ty_window
+The command to execute for a window system associated with the line.
+.It Fa ty_comment
+Any trailing comment field, with any leading hash marks (``#'') or
+whitespace removed.

+.Sh NAME
+.Nm glob ,
+.Nm globfree
+.Nd generate pathnames matching a pattern
+.Sh SYNOPSIS
+.Fd #include <glob.h>
+.Ft int
+.Fn glob "const char *pattern" "int flags" "const int (*errfunc)(const char *, int)" "glob_t *pglob"
+.Ft void 
+.Fn globfree "glob_t *pglob"
+.Sh DESCRIPTION
+The
+.Fn glob
+function
+is a pathname generator that implements the rules for file name pattern
+matching used by the shell.
+.Pp
+The include file
+.Pa glob.h
+defines the structure type
+.Fa glob_t ,
+which contains at least the following fields:
+.Bd -literal
+typedef struct {
+	int gl_pathc;		/* count of total paths so far */
+	int gl_matchc;		/* count of paths matching pattern */
+	int gl_offs;		/* reserved at beginning of gl_pathv */
+	int gl_flags;		/* returned flags */
+	char **gl_pathv;	/* list of paths matching pattern */
+} glob_t;
+.Ed
+.Pp
+The argument
+.Fa pattern
+is a pointer to a pathname pattern to be expanded.
+The
+.Fn glob
+argument
+matches all accessible pathnames against the pattern and creates
+a list of the pathnames that match.
+In order to have access to a pathname,
+.Fn glob
+requires search permission on every component of a path except the last
+and read permission on each directory of any filename component of
+.Fa pattern
+that contains any of the special characters
+.Ql * ,
+.Ql ?
+or
+.Ql [ .
+.Pp
+The
+.Fn glob
+argument
+stores the number of matched pathnames into the
+.Fa gl_pathc
+field, and a pointer to a list of pointers to pathnames into the
+.Fa gl_pathv
+field.
+The first pointer after the last pathname is
+.Dv NULL . 
+If the pattern does not match any pathnames, the returned number of
+matched paths is set to zero.
+.Pp
+It is the caller's responsibility to create the structure pointed to by
+.Fa pglob .
+The
+.Fn glob
+function allocates other space as needed, including the memory pointed
+to by
+.Fa gl_pathv .
+.Pp
+The argument
+.Fa flags
+is used to modify the behavior of
+.Fn glob .
+The value of
+.Fa flags
+is the bitwise inclusive
+.Tn OR
+of any of the following
+values defined in
+.Pa glob.h :
+.Bl -tag -width GLOB_ALTDIRFUNC
+.It Dv GLOB_APPEND
+Append pathnames generated to the ones from a previous call (or calls)
+to
+.Fn glob .
+The value of
+.Fa gl_pathc
+will be the total matches found by this call and the previous call(s).
+The pathnames are appended to, not merged with the pathnames returned by
+the previous call(s).
+Between calls, the caller must not change the setting of the
+.Dv GLOB_DOOFFS
+flag, nor change the value of
+.Fa gl_offs
+when
+.Dv GLOB_DOOFFS
+is set, nor (obviously) call
+.Fn globfree
+for
+.Fa pglob .
+.It Dv GLOB_DOOFFS
+Make use of the
+.Fa gl_offs
+field.
+If this flag is set,
+.Fa gl_offs
+is used to specify how many
+.Dv NULL
+pointers to prepend to the beginning
+of the
+.Fa gl_pathv
+field.
+In other words,
+.Fa gl_pathv
+will point to
+.Fa gl_offs
+.Dv NULL
+pointers,
+followed by
+.Fa gl_pathc
+pathname pointers, followed by a
+.Dv NULL
+pointer.
+.It Dv GLOB_ERR
+Causes
+.Fn glob
+to return when it encounters a directory that it cannot open or read.
+Ordinarily,
+.Fn glob
+continues to find matches.
+.It Dv GLOB_MARK
+Each pathname that is a directory that matches
+.Fa pattern
+has a slash
+appended.
+.It Dv GLOB_NOCHECK
+If
+.Fa pattern
+does not match any pathname, then
+.Fn glob
+returns a list
+consisting of only
+.Fa pattern ,
+with the number of total pathnames is set to 1, and the number of matched
+pathnames set to 0.
+If
+.Dv GLOB_QUOTE
+is set, its effect is present in the pattern returned.
+.It Dv GLOB_NOSORT
+By default, the pathnames are sorted in ascending
+.Tn ASCII
+order;
+this flag prevents that sorting (speeding up
+.Fn glob ) .
+.El
+.Pp
+The following values may also be included in
+.Fa flags ,
+however, they are non-standard extensions to
+.St -p1003.2 .
+.Bl -tag -width GLOB_ALTDIRFUNC
+.It Dv GLOB_ALTDIRFUNC
+The following additional fields in the pglob structure have been
+initialized with alternate functions for glob to use to open, read,
+and close directories and to get stat information on names found
+in those directories.
+.Bd -literal
+	void *(*gl_opendir)(const char * name);
+	struct dirent *(*gl_readdir)(void *);
+	void (*gl_closedir)(void *);
+	int (*gl_lstat)(const char *name, struct stat *st);
+	int (*gl_stat)(const char *name, struct stat *st);
+.Ed
+.Pp
+This extension is provided to allow programs such as
+.Xr restore 8
+to provide globbing from directories stored on tape.
+.It Dv GLOB_BRACE
+Pre-process the pattern string to expand 
+.Ql {pat,pat,...} 
+strings like 
+.Xr csh 1. The pattern 
+.Ql {}
+is left unexpanded for historical reasons
+.Xr (Csh 1 
+does the same thing to 
+ease typing
+of 
+.Xr find 1 
+patterns).
+.It Dv GLOB_MAGCHAR
+Set by the
+.Fn glob
+function if the pattern included globbing characters.
+See the description of the usage of the 
+.Fa gl_matchc
+structure member for more details.
+.It Dv GLOB_NOMAGIC
+Is the same as 
+.Dv GLOB_NOCHECK 
+but it only appends the
+.Fa pattern
+if it does not contain any of the special characters ``*'', ``?'' or ``[''.
+.Dv GLOB_NOMAGIC 
+is provided to simplify implementing the historic
+.Xr csh 1
+globbing behavior and should probably not be used anywhere else.
+.It Dv GLOB_QUOTE
+Use the backslash
+.Pq Ql \e
+character for quoting: every occurrence of
+a backslash followed by a character in the pattern is replaced by that
+character, avoiding any special interpretation of the character.
+.It Dv GLOB_TILDE
+Expand patterns that start with
+.Ql ~
+to user name home directories.
+.El
+.Pp
+If, during the search, a directory is encountered that cannot be opened
+or read and
+.Fa errfunc
+is
+.Pf non- Dv NULL , 
+.Fn glob
+calls
+.Fa (*errfunc)(path, errno) .
+This may be unintuitive: a pattern like
+.Ql */Makefile
+will try to
+.Xr stat 2
+.Ql foo/Makefile
+even if
+.Ql foo
+is not a directory, resulting in a
+call to
+.Fa errfunc .
+The error routine can suppress this action by testing for
+.Dv ENOENT
+and
+.Dv ENOTDIR ; 
+however, the
+.Dv GLOB_ERR
+flag will still cause an immediate
+return when this happens.
+.Pp
+If
+.Fa errfunc
+returns non-zero,
+.Fn glob
+stops the scan and returns
+.Dv GLOB_ABEND
+after setting
+.Fa gl_pathc
+and
+.Fa gl_pathv
+to reflect any paths already matched.
+This also happens if an error is encountered and
+.Dv GLOB_ERR
+is set in
+.Fa flags ,
+regardless of the return value of
+.Fa errfunc ,
+if called.
+If
+.Dv GLOB_ERR
+is not set and either
+.Fa errfunc
+is
+.Dv NULL
+or
+.Fa errfunc
+returns zero, the error is ignored.
+.Pp
+The
+.Fn globfree
+function frees any space associated with
+.Fa pglob
+from a previous call(s) to
+.Fn glob .
+.Sh RETURN VALUES
+On successful completion,
+.Fn glob
+returns zero.
+In addition the fields of
+.Fa pglob
+contain the values described below:
+.Bl -tag -width GLOB_NOCHECK
+.It Fa gl_pathc
+contains the total number of matched pathnames so far.
+This includes other matches from previous invocations of 
+.Fn glob
+if 
+.Dv GLOB_APPEND
+was specified.
+.It Fa gl_matchc
+contains the number of matched pathnames in the current invocation of
+.Fn glob .
+.It Fa gl_flags
+contains a copy of the 
+.Fa flags
+parameter with the bit
+.Dv GLOB_MAGCHAR
+set if
+.Fa pattern
+contained any of the special characters ``*'', ``?'' or ``['', cleared
+if not.
+.It Fa gl_pathv
+contains a pointer to a

+.Pp
+If
+.Fn glob
+terminates due to an error, it sets 
+.Va errno 
+and returns one of the following non-zero constants, which are defined 
+in the include file
+.Aq Pa glob.h :
+.Bl -tag -width GLOB_NOCHECK
+.It Dv GLOB_NOSPACE
+An attempt to allocate memory failed.
+.It Dv GLOB_ABEND
+The scan was stopped because an error was encountered and either

+glob_t g;
+
+g.gl_offs = 2;

+.Sh DESCRIPTION
+.Bf -symbolic
+This interface is obsoleted by setpriority(2).
+.Ef
+.Pp
+The
+.Fn nice
+function obtains the scheduling priority of the process
+from the system and sets it to the priority value specified in
+.Fa incr .
+The priority is a value in the range -20 to 20.
+The default priority is 0; lower priorities cause more favorable scheduling.
+Only the super-user may lower priorities.
+.Pp
+Children inherit the priority of their parent processes via
+.Xr fork 2 .

+.Sh NAME
+.Nm popen ,
+.Nm pclose
+.Nd process
+.Tn I/O
+.Sh SYNOPSIS
+.Fd #include <stdio.h>
+.Ft FILE *
+.Fn popen "const char *command" "const char *type"
+.Ft int
+.Fn pclose "FILE *stream"
+.Sh DESCRIPTION
+The
+.Fn popen
+function
+.Dq opens
+a process by creating a pipe,
+forking,
+and invoking the shell.
+Since a pipe is by definition unidirectional, the
+.Fa type
+argument may specify only reading or writing, not both;
+the resulting stream is correspondingly read-only or write-only.
+.Pp
+The
+.Fa command
+argument is a pointer to a null-terminated string
+containing a shell command line.
+This command is passed to
+.Pa /bin/sh
+using the
+.Fl c
+flag; interpretation, if any, is performed by the shell.
+The
+.Fa mode
+argument is a pointer to a null-terminated string
+which must be either
+.Ql r
+for reading
+or
+.Ql w
+for writing.
+.Pp
+The return value from
+.Fn popen
+is a normal standard
+.Tn I/O
+stream in all respects
+save that it must be closed with
+.Fn pclose
+rather than
+.Fn fclose .
+Writing to such a stream
+writes to the standard input of the command;
+the command's standard output is the same as that of the process that called
+.Fn popen ,
+unless this is altered by the command itself.
+Conversely, reading from a
+.Dq popened
+stream reads the command's standard output, and
+the command's standard input is the same as that of the process that called
+.Fn popen .
+.Pp
+Note that output
+.Fn popen
+streams are fully buffered by default.
+.Pp
+The
+.Fn pclose
+function waits for the associated process to terminate
+and returns the exit status of the command
+as returned by
+.Fn wait4 .
+.Sh RETURN VALUE
+The
+.Fn popen
+function returns
+.Dv NULL
+if the
+.Xr fork 2
+or
+.Xr pipe 2
+calls fail,
+or if it cannot allocate memory.
+.Pp
+The
+.Fn pclose
+function
+returns \-1 if
+.Fa stream
+is not associated with a
+.Dq popened
+command, if
+.Fa stream
+already
+.Dq pclosed ,
+or if
+.Xr wait4
+returns an error.
+.Sh ERRORS
+The
+.Fn popen
+function does not reliably set
+.Va errno .
+.Sh SEE ALSO
+.Xr fork 2 ,
+.Xr sh 1 ,
+.Xr pipe 2 ,
+.Xr wait4 2 ,
+.Xr fflush 3 ,
+.Xr fclose 3 ,
+.Xr fopen 3 ,
+.Xr stdio 3 ,
+.Xr system 3
+.Sh BUGS
+Since the standard input of a command opened for reading
+shares its seek offset with the process that called
+.Fn popen ,
+if the original process has done a buffered read,
+the command's input position may not be as expected.
+Similarly, the output from a command opened for writing
+may become intermingled with that of the original process.
+The latter can be avoided by calling
+.Xr fflush 3
+before
+.Fn popen .
+.Pp
+Failure to execute the shell
+is indistinguishable from the shell's failure to execute command,
+or an immediate exit of the command.
+The only hint is an exit status of 127.
+.Pp
+The
+.Fn popen
+argument
+always calls
+.Xr sh ,
+never calls
+.Xr csh .
+.Sh HISTORY
+A
+.Fn popen
+and a
+.Fn pclose
+function appeared in

+.Sh DESCRIPTION
+The
+.Fn scandir
+function
+reads the directory
+.Fa dirname
+and builds an array of pointers to directory
+entries using
+.Xr malloc 3 .
+It returns the number of entries in the array.
+A pointer to the array of directory entries is stored in the location
+referenced by
+.Fa namelist .
+.Pp
+The
+.Fa select
+parameter is a pointer to a user supplied subroutine which is called by
+.Fn scandir
+to select which entries are to be included in the array.
+The select routine is passed a
+pointer to a directory entry and should return a non-zero
+value if the directory entry is to be included in the array.
+If
+.Fa select
+is null, then all the directory entries will be included.

+The
+.Fa compar
+parameter is a pointer to a user supplied subroutine which is passed to
+.Xr qsort 3
+to sort the completed array.
+If this pointer is null, the array is not sorted.
+.Pp
+The
+.Fn alphasort
+function
+is a routine which can be used for the
+.Fa compar
+parameter to sort the array alphabetically.
+.Pp
+The memory allocated for the array can be deallocated with
+.Xr free 3 ,
+by freeing each pointer in the array and then the array itself.
+.Sh DIAGNOSTICS
+Returns \-1 if the directory cannot be opened for reading or if

+.Sh DESCRIPTION
+The
+.Fn sigsetjmp ,
+.Fn setjmp ,
+and
+.Fn _setjmp
+functions save their calling environment in
+.Fa env .
+Each of these functions returns 0.
+.Pp
+The corresponding
+.Fn longjmp
+functions restore the environment saved by their most recent respective
+invocations
+of the
+.Fn setjmp
+function.
+They then return so that program execution continues as if the corresponding
+invocation of the
+.Fn setjmp
+call had just returned  the value specified by
+.Fa val ,
+instead of 0.
+.Pp
+Pairs of calls may be intermixed, i.e. both
+.Fn sigsetjmp
+and
+.Fn siglongjmp
+and
+.Fn setjmp
+and
+.Fn longjmp
+combinations may be used in the same program, however, individual
+calls may not, e.g. the
+.Fa env
+argument to
+.Fn setjmp
+may not be passed to
+.Fn siglongjmp .
+.Pp
+The
+.Fn longjmp
+routines may not be called after the routine which called the
+.Fn setjmp
+routines returns.
+.Pp
+All accessible objects have values as of the time
+.Fn longjmp
+routine was called, except that the values of objects of automatic storage
+invocation duration that do not have the
+.Em volatile
+type and have been changed between the
+.Fn setjmp
+invocation and
+.Fn longjmp
+call are indeterminate.
+.Pp
+The
+.Fn setjmp Ns / Ns Fn longjmp
+pairs save and restore the signal mask while
+.Fn _setjmp Ns / Ns Fn _longjmp
+pairs save and restore only the register set and the stack.
+(See
+.Fn sigmask 2 . )
+.Pp
+The
+.Fn sigsetjmp Ns / Ns Fn siglongjmp
+function
+pairs save and restore the signal mask if the argument
+.Fa savemask
+is non-zero, otherwise only the register set and the stack are saved.
+.Sh ERRORS
+If the contents of the
+.Fa env
+are corrupted, or correspond to an environment that has already returned,
+the
+.Fn longjmp
+routine calls the routine
+.Fn longjmperror 3 .
+If
+.Fn longjmperror
+returns the program is aborted (see
+.Xr abort 2 ) .
+The default version of
+.Fn longjmperror
+prints the message
+.Dq Li longjmp botch
+to standard error and returns.
+User programs wishing to exit more gracefully should write their own
+versions of
+.Fn longjmperror .

+.Sh NAME
+.Nm getmode ,
+.Nm setmode
+.Nd modify mode bits
+.Sh SYNOPSIS
+.Ft mode_t
+.Fn getmode "const void *set" "mode_t mode"
+.Ft void
+.Fn setmode "const char *mode_str"
+.Sh DESCRIPTION
+The
+.Fn getmode
+function
+returns a copy of the file permission bits
+.Fa mode
+as altered by the values pointed to by
+.Fa set .
+While only the mode bits are altered, other parts of the file mode
+may be examined.
+.Pp
+The
+.Fn setmode
+function
+takes an absolute (octal) or symbolic value, as described in
+.Xr chmod 1 ,
+as an argument
+and returns a pointer to mode values to be supplied to
+.Fn getmode .
+Because some of the symbolic values are relative to the file
+creation mask,
+.Fn setmode
+may call
+.Xr umask 2 .
+If this occurs, the file creation mask will be restored before
+.Fn setmode
+returns.
+If the calling program changes the value of its file creation mask
+after calling
+.Fn setmode ,
+.Fn setmode
+must be called again if
+.Fn getmode
+is to modify future file modes correctly.
+.Pp
+If the mode passed to
+.Fn setmode
+is invalid,
+.Fn setmode
+returns
+.Dv NULL . 
+.Sh ERRORS
+The
+.Fn setmode
+function
+may fail and set errno for any of the errors specified for the library
+routine
+.Xr malloc 3 .
+.Sh SEE ALSO
+.Xr chmod 1 ,
+.Xr stat 2 ,
+.Xr umask 2 ,
+.Xr malloc 3
+.Sh HISTORY
+The
+.Fn getmode
+and
+.Fn setmode
+functions first appeared in 4.4BSD.

+.Os BSD 4.3
+.Sh NAME
+.Nm siginterrupt
+.Nd allow signals to interrupt system calls
+.Sh SYNOPSIS
+.Fd #include <signal.h>
+.Ft int
+.Fn siginterrupt "int sig" "int flag"
+.Sh DESCRIPTION
+The
+.Fn siginterrupt
+function
+is used to change the system call restart
+behavior when a system call is interrupted by the specified signal.
+If the flag is false (0), then system calls will be restarted if
+they are interrupted by the specified signal
+and no data has been transferred yet.
+System call restart is the default behavior on
+.Bx 4.2 .
+.Pp
+If the flag is true (1),
+then restarting of system calls is disabled.
+If a system call is interrupted by the specified signal
+and no data has been transferred,
+the system call will return \-1 with the global variable
+.Va errno
+set to
+.Dv EINTR . 
+Interrupted system calls that have started transferring
+data will return the amount of data actually transferred.
+System call interrupt is the signal behavior found on
+.Bx 4.1
+and
+.At V
+systems.
+.Pp
+Note that the new
+.Bx 4.2
+signal handling semantics are not
+altered in any other way.
+Most notably, signal handlers always remain installed until
+explicitly changed by a subsequent
+.Xr sigaction 2
+call, and the signal mask operates as documented in
+.Xr sigaction 2 .
+Programs may switch between restartable and interruptible
+system call operation as often as desired in the execution of a program.
+.Pp
+Issuing a
+.Fn siginterrupt 3
+call during the execution of a signal handler will cause
+the new action to take place on the next signal to be caught.
+.Sh NOTES
+This library routine uses an extension of the
+.Xr sigaction 2
+system call that is not available in
+.Bx 4.2 ,
+hence it should not be used if backward compatibility is needed.
+.Sh RETURN VALUES
+A 0 value indicates that the call succeeded.
+A \-1 value indicates that an invalid signal number has been supplied.
+.Sh SEE ALSO
+.Xr sigaction 2 ,
+.Xr sigblock 2 ,
+.Xr sigpause 2 ,
+.Xr sigsetmask 2 .
+.Sh HISTORY
+The
+.Fn siginterrupt
+function appeared in 
+.Bx 4.3 .

+.Sh DESCRIPTION
+This
+.Fn signal
+facility
+is a simplified interface to the more general
+.Xr sigaction 2
+facility.
+.Pp
+Signals allow the manipulation of a process from outside its
+domain as well as allowing the process to manipulate itself or
+copies of itself (children). There are two general types of signals:
+those that cause termination of a process and those that do not.
+Signals which cause termination of a program might result from
+an irrecoverable error or might be the result of a user at a terminal
+typing the `interrupt' character.
+Signals are used when a process is stopped because it wishes to access
+its control terminal while in the background (see
+.Xr tty 4 ) .
+Signals are optionally generated
+when a process resumes after being stopped,
+when the status of child processes changes,
+or when input is ready at the control terminal.
+Most signals result in the termination of the process receiving them
+if no action
+is taken; some signals instead cause the process receiving them
+to be stopped, or are simply discarded if the process has not
+requested otherwise.
+Except for the
+.Dv SIGKILL
+and
+.Dv SIGSTOP
+signals, the
+.Fn signal
+function allows for a signal to be caught, to be ignored, or to generate
+an interrupt.
+These signals are defined in the file
+.Aq Pa signal.h :

+.El
+.Pp
+The
+.Fa func
+procedure allows a user to choose the action upon receipt of a signal.
+To set the default action of the signal to occur as listed above,
+.Fa func
+should be
+.Dv SIG_DFL .
+A
+.Dv SIG_DFL
+resets the default action.
+To ignore the signal
+.Fa func
+should be
+.Dv SIG_IGN .
+This will cause subsequent instances of the signal to be ignored
+and pending instances to be discarded. If
+.Dv SIG_IGN
+is not used,
+further occurrences of the signal are
+automatically blocked and
+.Fa func
+is called.
+.Pp
+The handled signal is unblocked with the
+function returns and
+the process continues from where it left off when the signal occurred.
+.Bf -symbolic
+Unlike previous signal facilities, the handler
+func() remains installed after a signal has been delivered.
+.Ef
+.Pp
+For some system calls, if a signal is caught while the call is
+executing and the call is prematurely terminated,
+the call is automatically restarted.
+(The handler is installed using the
+.Dv SA_RESTART
+flag with
+.Xr sigaction 2 . )
+The affected system calls include
+.Xr read 2 ,
+.Xr write 2 ,
+.Xr sendto 2 ,
+.Xr recvfrom 2 ,
+.Xr sendmsg 2
+and
+.Xr recvmsg 2
+on a communications channel or a low speed device
+and during a
+.Xr ioctl 2
+or
+.Xr wait 2 .
+However, calls that have already committed are not restarted,
+but instead return a partial success (for example, a short read count).
+.Pp
+When a process which has installed signal handlers forks,
+the child process inherits the signals.
+All caught signals may be reset to their default action by a call
+to the
+.Xr execve 2
+function;
+ignored signals remain ignored.
+.Sh RETURN VALUES
+The previous action is returned on a successful call.
+Otherwise, \-1 is returned and  the global variable
+.Va errno
+is set to indicate the error.
+.Sh ERRORS
+.Xr Signal
+will fail and no action will take place if one of the
+following occur:
+.Bl -tag -width Er
+.It Bq Er EINVAL
+.Em Sig
+is not a valid signal number.
+.It Bq Er EINVAL
+An attempt is made to ignore or supply a handler for
+.Dv SIGKILL
+or
+.Ev SIGSTOP .

+.Dt SLEEP 3
+.Os
+.Sh NAME
+.Nm sleep
+.Nd suspend process execution for interval of seconds
+.Sh SYNOPSIS
+.Fd #include <unistd.h>
+.Ft unsigned int
+.Fn sleep "unsigned int seconds"
+.Sh DESCRIPTION
+The
+.Fn sleep
+function suspends execution of the calling process until either the
+number of seconds specified by
+.Fa seconds
+have elapsed or a signal is delivered to the calling process and its
+action is to invoke a signal-catching function or to terminate the
+process.  The suspension time may be longer than requested due to the
+scheduling of other activity by the system.
+.Pp
+If a timer is already running on the process its state is saved.
+If the value
+.Fa seconds
+is more than or equal to the remaining clock time for the saved timer,
+the sleep time is set to
+the remaining clock time.
+The state of the previous timer
+is restored after
+.Fa seconds
+has passed.
+.Pp
+This function is implemented using
+.Xr setitimer 2 ;
+it requires eight system calls each time it is invoked.
+A similar but less compatible function can be obtained with a single
+.Xr select 2 ;
+such a function would not restart after signals, but would not interfere
+with other uses of
+.Xr setitimer .
+.Sh RETURN VALUE
+If the 
+.Fn sleep
+function returns because the requested time has elapsed, the value
+returned will be zero.  If the 
+.Fn sleep
+function returns due to the delivery of a signal, the value returned
+will be the unslept amount (the request time minus the time actually
+slept) in seconds.
+.Sh SEE ALSO
+.Xr setitimer 2 ,
+.Xr sigaction 2 ,
+.Xr sigsuspend 2 ,
+.Xr alarm 3 ,
+.Xr pause 3 ,
+.Xr usleep 3
+.Sh STANDARDS
+The 
+.Fn sleep 
+function conforms to 
+.St -p1003.1-90 .
+.Sh HISTORY
+A
+.Fn sleep
+function appeared in
+.At v7 .

+.Sh RETURN VALUES
+If the call to
+.Nm sysconf
+is not successful, \-1 is returned and
+.Va errno
+is set appropriately.
+Otherwise, if the variable is associated with functionality that is not
+supported, \-1 is returned and
+.Va errno
+is not modified.
+Otherwise, the current variable value is returned.
+.Sh ERRORS
+The
+.Fn sysconf
+function may fail and set
+.Va errno
+for any of the errors specified for the library functions
+.Xr sysctl 3 .
+In addition, the following error may be reported:
+.Bl -tag -width Er
+.It Bq Er EINVAL
+The value of the
+.Fa name
+argument is invalid.
+.Sh SEE ALSO
+.Xr sysctl 3
+.Sh BUGS
+The value for _SC_STREAM_MAX is a minimum maximum, and required to be
+the same as ANSI C's FOPEN_MAX, so the returned value is a ridiculously
+small and misleading number.
+.Sh STANDARDS
+The
+.Fn sysconf
+function conforms to
+.St -p1003.1-88 .
+.Sh HISTORY
+The
+.Nm sysconf
+function first appeared in 4.4BSD.

+.Sh NAME
+.Nm sysctl
+.Nd get or set system information
+.Sh SYNOPSIS
+.Fd #include <sys/sysctl.h>
+.Ft int
+.Fn sysctl "int *name" "u_int namelen" "void *oldp" "size_t *oldlenp" "void *newp" "size_t newlen"
+.Sh DESCRIPTION
+The
+.Nm sysctl
+function retrieves system information and allows processes with
+appropriate privileges to set system information.
+The information available from
+.Nm sysctl
+consists of integers, strings, and tables.
+Information may be retrieved and set from the command interface
+using the 
+.Xr sysctl 8
+utility.
+.Pp
+Unless explicitly noted below,
+.Nm sysctl
+returns a consistent snapshot of the data requested.
+Consistency is obtained by locking the destination
+buffer into memory so that the data may be copied out without blocking.
+Calls to
+.Nm sysctl
+are serialized to avoid deadlock.
+.Pp
+The state is described using a ``Management Information Base'' (MIB)
+style name, listed in
+.Fa name ,
+which is a
+.Fa namelen
+length array of integers.
+.Pp
+The information is copied into the buffer specified by
+.Fa oldp .
+The size of the buffer is given by the location specified by
+.Fa oldlenp
+before the call,
+and that location gives the amount of data copied after a successful call.
+If the amount of data available is greater
+than the size of the buffer supplied,
+the call supplies as much data as fits in the buffer provided
+and returns with the error code ENOMEM.
+If the old value is not desired,
+.Fa oldp
+and
+.Fa oldlenp
+should be set to NULL.
+.Pp
+The size of the available data can be determined by calling 
+.Nm sysctl
+with a NULL parameter for
+.Fa oldp .
+The size of the available data will be returned in the location pointed to by
+.Fa oldlenp .
+For some operations, the amount of space may change often.
+For these operations,
+the system attempts to round up so that the returned size is
+large enough for a call to return the data shortly thereafter.
+.Pp
+To set a new value,
+.Fa newp
+is set to point to a buffer of length
+.Fa newlen
+from which the requested value is to be taken.
+If a new value is not to be set,
+.Fa newp
+should be set to NULL and
+.Fa newlen
+set to 0.
+.Pp
+The top level names are defined with a CTL_ prefix in
+.Pa <sys/sysctl.h> ,
+and are as follows.
+The next and subsequent levels down are found in the include files
+listed here, and described in separate sections below.
+.Pp

+For example, the following retrieves the maximum number of processes allowed
+in the system:
+.Bd -literal -offset indent -compact
+int mib[2], maxproc;
+size_t len;
+.sp
+mib[0] = CTL_KERN;
+mib[1] = KERN_MAXPROC;
+len = sizeof(maxproc);
+sysctl(mib, 2, &maxproc, &len, NULL, 0);
+.Ed
+.sp
+To retrieve the standard search path for the system utilities:
+.Bd -literal -offset indent -compact
+int mib[2];
+size_t len;
+char *p;
+.sp
+mib[0] = CTL_USER;
+mib[1] = USER_CS_PATH;
+sysctl(mib, 2, NULL, &len, NULL, 0);
+p = malloc(len);
+sysctl(mib, 2, p, &len, NULL, 0);
+.Ed
+.Sh CTL_DEBUG
+The debugging variables vary from system to system.
+A debugging variable may be added or deleted without need to recompile
+.Nm sysctl
+to know about it.
+Each time it runs,
+.Nm sysctl
+gets the list of debugging variables from the kernel and
+displays their current values.
+The system defines twenty 
+.Ns ( Va struct ctldebug )
+variables named 
+.Nm debug0
+through
+.Nm debug19 .
+They are declared as separate variables so that they can be
+individually initialized at the location of their associated variable.
+The loader prevents multiple use of the same variable by issuing errors
+if a variable is initialized in more than one place.
+For example, to export the variable
+.Nm dospecialcheck
+as a debugging variable, the following declaration would be used:
+.Bd -literal -offset indent -compact
+int dospecialcheck = 1;
+struct ctldebug debug5 = { "dospecialcheck", &dospecialcheck };

+.Sh SYNOPSIS
+.Fd #include <syslog.h>
+.Fd #include <varargs.h>
+.Ft void
+.Fn syslog "int priority" "const char *message" "..."
+.Ft void
+.Fn vsyslog "int priority" "const char *message" "va_list args"
+.Ft void
+.Fn openlog "const char *ident" "int logopt" "int facility"
+.Ft void
+.Fn closelog void
+.Ft int
+.Fn setlogmask "int maskpri"
+.Sh DESCRIPTION
+The
+.Fn syslog
+function
+writes
+.Fa message
+to the system message logger.
+The message is then written to the system console, log files,
+logged-in users, or forwarded to other machines as appropriate. (See
+.Xr syslogd 8 . )
+.Pp
+The message is identical to a
+.Xr printf 3
+format string, except that
+.Ql %m
+is replaced by the current error
+message. (As denoted by the global variable
+.Va errno ;
+see
+.Xr strerror 3 . )
+A trailing newline is added if none is present.
+.Pp
+The
+.Fn vsyslog
+function
+is an alternate form in which the arguments have already been captured
+using the variable-length argument facilities of
+.Xr varargs 3 .
+.Pp
+The message is tagged with
+.Fa priority .
+Priorities are encoded as a
+.Fa facility
+and a
+.Em level .
+The facility describes the part of the system
+generating the message.
+The level is selected from the following
+.Em ordered
+(high to low) list:
+.Bl -tag -width LOG_AUTHPRIV
+.It Dv LOG_EMERG
+A panic condition.
+This is normally broadcast to all users.
+.It Dv LOG_ALERT
+A condition that should be corrected immediately, such as a corrupted
+system database.
+.It Dv LOG_CRIT
+Critical conditions, e.g., hard device errors.
+.It Dv LOG_ERR
+Errors.
+.It Dv LOG_WARNING
+Warning messages.
+.It Dv LOG_NOTICE
+Conditions that are not error conditions,
+but should possibly be handled specially.
+.It Dv LOG_INFO
+Informational messages.
+.It Dv LOG_DEBUG
+Messages that contain information
+normally of use only when debugging a program.
+.El
+.Pp
+The
+.Fn openlog
+function
+provides for more specialized processing of the messages sent
+by
+.Fn syslog
+and
+.Fn vsyslog .
+The parameter
+.Fa ident
+is a string that will be prepended to every message.
+The
+.Fa logopt
+argument
+is a bit field specifying logging options, which is formed by
+.Tn OR Ns 'ing
+one or more of the following values:
+.Bl -tag -width LOG_AUTHPRIV
+.It Dv LOG_CONS
+If
+.Fn syslog
+cannot pass the message to
+.Xr syslogd
+it will attempt to write the message to the console
+.Pq Dq Pa /dev/console.
+.It Dv LOG_NDELAY 
+Open the connection to
+.Xr syslogd
+immediately.
+Normally the open is delayed until the first message is logged.
+Useful for programs that need to manage the order in which file
+descriptors are allocated.
+.It Dv LOG_PERROR
+Write the message to standard error output as well to the system log.
+.It Dv LOG_PID
+Log the process id with each message: useful for identifying
+instantiations of daemons.
+.El
+.Pp
+The
+.Fa facility
+parameter encodes a default facility to be assigned to all messages
+that do not have an explicit facility encoded:
+.Bl -tag -width LOG_AUTHPRIV
+.It Dv LOG_AUTH
+The authorization system:
+.Xr login 1 ,
+.Xr su 1 ,
+.Xr getty 8 ,
+etc.
+.It Dv LOG_AUTHPRIV
+The same as
+.Dv LOG_AUTH ,
+but logged to a file readable only by
+selected individuals.
+.It Dv LOG_CRON
+The cron daemon:
+.Xr cron 8 .
+.It Dv LOG_DAEMON
+System daemons, such as
+.Xr routed 8 ,
+that are not provided for explicitly by other facilities.
+.It Dv LOG_FTP
+The file transfer protocol daemon:
+.Xr ftpd 8 .
+.It Dv LOG_KERN
+Messages generated by the kernel.
+These cannot be generated by any user processes.
+.It Dv LOG_LPR
+The line printer spooling system:
+.Xr lpr 1 ,
+.Xr lpc 8 ,
+.Xr lpd 8 ,
+etc.
+.It Dv LOG_MAIL
+The mail system.
+.It Dv LOG_NEWS
+The network news system.
+.It Dv LOG_SYSLOG
+Messages generated internally by
+.Xr syslogd 8 .
+.It Dv LOG_USER
+Messages generated by random user processes.
+This is the default facility identifier if none is specified.
+.It Dv LOG_UUCP
+The uucp system.
+.It Dv LOG_LOCAL0
+Reserved for local use.
+Similarly for
+.Dv LOG_LOCAL1
+through
+.Dv LOG_LOCAL7 .
+.El 
+.Pp
+The
+.Fn closelog
+function
+can be used to close the log file.
+.Pp
+The
+.Fn setlogmask
+function
+sets the log priority mask to
+.Fa maskpri
+and returns the previous mask.
+Calls to
+.Fn syslog
+with a priority not set in
+.Fa maskpri
+are rejected.
+The mask for an individual priority
+.Fa pri
+is calculated by the macro
+.Fn LOG_MASK pri ;
+the mask for all priorities up to and including
+.Fa toppri
+is given by the macro
+.Fn LOG_UPTO toppri ; .
+The default allows all priorities to be logged.
+.Sh RETURN VALUES
+The routines
+.Fn closelog ,
+.Fn openlog ,
+.Fn syslog
+and
+.Fn vsyslog
+return no value.
+.Pp
+The routine
+.Fn setlogmask
+always returns the previous log mask level.
+.Sh EXAMPLES
+.Bd -literal -offset indent -compact
+syslog(LOG_ALERT, "who: internal error 23");
+
+openlog("ftpd", LOG_PID | LOG_NDELAY, LOG_FTP);

+.Fd #include <unistd.h>
+.Ft char *
+.Fn ttyname "int fd"
+.Ft int
+.Fn isatty "int fd"
+.Ft int
+.Fn ttyslot 
+.Sh DESCRIPTION
+These functions operate on the system file descriptors for terminal
+type devices. These descriptors are not related to the standard
+.Tn I/O
+.Dv FILE
+typedef, but refer to the special device files found in
+.Pa /dev
+and named
+.Pa /dev/tty Ns Em xx
+and for which an entry exists
+in the initialization file
+.Pa /etc/ttys.
+(See
+.Xr ttys 5 . )
+.Pp
+The
+.Fn isatty
+function
+determines if the file descriptor
+.Fa fd
+refers to a valid
+terminal type device.
+.Pp
+The
+.Fn ttyname
+function
+gets the related device name of
+a file descriptor for which
+.Fn isatty
+is true
+.Pp
+The
+.Fn ttyslot
+function
+fetches the current process' control terminal number from the
+.Xr ttys 5
+file entry.
+.Sh RETURN VALUES
+The
+.Fn ttyname
+function
+returns the null terminated name if the device is found and
+.Fn isatty
+is true; otherwise 
+a
+.Dv NULL
+pointer is returned.
+.Pp
+The
+.Fn ttyslot
+function
+returns the unit number of the device file if found; otherwise
+the value zero is returned.

+function leaves its result in an internal static object and returns
+a pointer to that object. Subsequent calls to
+.Fn ttyname
+will modify the same object.

+.Fa interval
+microseconds after the timer expires (e.g. after
+.Fa value
+microseconds have passed).
+.Sh RETURN VALUES
+When the signal has successfully been caught,
+.Fn alarm
+returns the amount of time left on the clock.
+The maximum number of
+.Ar microseconds

+.Sh NAME
+.Nm unvis ,
+.Nm strunvis
+.Nd decode a visual representation of characters
+.Sh SYNOPSIS
+.Fd #include <vis.h>
+.Ft int 
+.Fn unvis "u_char *cp" "u_char c" "int *astate" "int flag"
+.Ft int 
+.Fn strunvis "char *dst" "char *src"
+.Sh DESCRIPTION
+The
+.Fn unvis
+and
+.Fn strunvis
+functions
+are used to decode a visual representation of characters, as produced
+by the
+.Xr vis 3
+function, back into
+the original form.  Unvis is called with successive characters in
+.Ar c 
+until a valid
+sequence is recognized, at which time the decoded character is
+available at the character pointed to by
+.Ar cp .
+Strunvis decodes the
+characters pointed to by
+.Ar src
+into the buffer pointed to by
+.Ar dst .
+.Pp
+The
+.Fn strunvis
+function
+simply copies
+.Ar src
+to
+.Ar dst ,
+decoding any escape sequences along the way,
+and returns the number of characters placed into
+.Ar dst ,
+or \-1 if an
+invalid escape sequence was detected.  The size of
+.Ar dst
+should be
+equal to the size of
+.Ar src
+(that is, no expansion takes place during
+decoding).
+.Pp
+The
+.Fn unvis
+function
+implements a state machine that can be used to decode an arbitrary
+stream of bytes.  All state associated with the bytes being decoded
+is stored outside the
+.Fn unvis
+function (that is, a pointer to the state is passed in), so
+calls decoding different streams can be freely intermixed.  To
+start decoding a stream of bytes, first initialize an integer
+to zero.  Call
+.Fn unvis
+with each successive byte, along with a pointer
+to this integer, and a pointer to a destination character.
+The
+.Xr unvis
+function
+has several return codes that must be handled properly.  They are:
+.Bl -tag -width UNVIS_VALIDPUSH
+.It Li \&0 (zero)
+Another character is necessary; nothing has been recognized yet.
+.It Dv  UNVIS_VALID	
+A valid character has been recognized and is available at the location
+pointed to by cp.
+.It Dv  UNVIS_VALIDPUSH
+A valid character has been recognized and is available at the location
+pointed to by cp; however, the character currently passed in should
+be passed in again.
+.It Dv  UNVIS_NOCHAR
+A valid sequence was detected, but no character was produced.  This
+return code is necessary to indicate a logical break between characters.
+.It Dv  UNVIS_SYNBAD
+An invalid escape sequence was detected, or the decoder is in an
+unknown state.  The decoder is placed into the starting state.
+.El
+.Pp
+When all bytes in the stream have been processed, call
+.Fn unvis
+one more time with flag set to
+.Dv UNVIS_END
+to extract any remaining character (the character passed in is ignored).
+.Pp
+The following code fragment illustrates a proper use of
+.Fn unvis .
+.Bd -literal -offset indent
+int state = 0;
+char out;
+
+while ((ch = getchar()) != EOF) {
+again:
+	switch(unvis(&out, ch, &state, 0)) {

+	case UNVIS_NOCHAR:
+		break;
+	case UNVIS_VALID:
+		(void) putchar(out);
+		break;
+	case UNVIS_VALIDPUSH:
+		(void) putchar(out);
+		goto again;
+	case UNVIS_SYNBAD:
+		(void)fprintf(stderr, "bad sequence!\n");
+	exit(1);
+	}
+}
+if (unvis(&out, (char)0, &state, UNVIS_END) == UNVIS_VALID)

+.Ft void
+.Fn usleep "u_int microseconds"
+.Sh DESCRIPTION
+The
+.Fn usleep
+function
+suspends execution of the calling process
+for
+.Fa microseconds
+of time.
+System activity or time spent in processing the
+call may lengthen the sleep slightly.
+.Pp
+If a timer is already running on the process its state is saved.
+If the value
+.Fa microseconds
+is more than or equal to the remaining clock time for the saved timer,
+the sleep time is set to
+the remaining clock time.
+The state of the previous timer
+is restored after
+.Fa microseconds
+has passed.
+.Pp
+This routine is implemented using 
+.Xr setitimer 2 ;
+it requires eight system calls each time it is invoked.
+A similar but less compatible function can be obtained with a single
+.Xr select 2 ;
+such a function would not restart after signals, but would not interfere
+with other uses of
+.Xr setitimer .

+.Sh DESCRIPTION
+.Bf -symbolic
+This interface is obsoleted by utimes(2) .
+.Ef
+.Pp
+The
+.Fn utime
+function sets the access and modification times of the named file.
+.Pp
+If
+.Fa timep
+is
+.Dv NULL ,
+the access and modification times are set to the current time.
+The calling process must be the owner of the file or have permission to 
+write the file.
+.Pp
+If 
+.Fa timep
+is 
+.Pf non- Dv NULL ,
+.Fa time 
+is assumed to be a pointer to a utimbuf structure, as defined in 
+.Aq Pa utime.h :
+.Bd -literal -offset indent
+struct utimbuf {
+	time_t actime;          /* Access time */
+	time_t modtime;         /* Modification time */
+} ;
+.Ed
+.Pp
+The access time is set to the value of the actime member, and the modification
+time is set to the value of the modtime member.  The times are measured in
+seconds since 0 hours, 0 minutes, 0 seconds, January 1, 1970, Coordinated 
+Universal Time.
+The calling process must be the owner of the file or be the super-user.
+.Pp
+In either case, the inode-change-time of the file is set to the current 
+time.
+.Sh RETURN VALUES
+Upon successful completion, a value of 0 is returned.
+Otherwise, a value of -1 is returned and
+.Va errno
+is set to indicate the error.
+.Sh ERRORS
+.Fn Utime
+will fail if:
+.Bl -tag -width Er
+.It Bq Er EACCES
+Search permission is denied for a component of the path prefix;

+.It Bq Er EINVAL
+The pathname contains a character with the high-order bit set.
+.It Bq Er EIO
+An I/O error occurred while reading or writing the affected inode.
+.It Bq Er ELOOP
+Too many symbolic links were encountered in translating the pathname.
+.It Bq Er ENAMETOOLONG
+A component of a pathname exceeded 255 characters,
+or an entire path name exceeded 1023 characters.
+.It Bq Er ENOENT
+The named file does not exist.
+.It Bq Er ENOTDIR
+A component of the path prefix is not a directory.
+.It Bq Er EPERM

+.Sh NAME
+.Nm vis
+.Nd visually encode characters
+.Sh SYNOPSIS
+.Fd #include <vis.h>
+.Ft char *
+.Fn vis "char *dst" "char c" "int flag" "char nextc"
+.Ft int 
+.Fn strvis "char *dst" "char *src" "int flag"
+.Ft int 
+.Fn strvisx "char *dst" "char *src" "int len" "int flag"
+.Sh DESCRIPTION
+The
+.Fn vis
+function
+copies into
+.Fa dst
+a string which represents the character
+.Fa c .
+If
+.Fa c
+needs no encoding, it is copied in unaltered.  The string is
+null terminated, and a pointer to the end of the string is
+returned.  The maximum length of any encoding is four
+characters (not including the trailing
+.Dv NUL ) ; 
+thus, when
+encoding a set of characters into a buffer, the size of the buffer should
+be four times the number of characters encoded, plus one for the trailing
+.Dv NUL . 
+The flag parameter is used for altering the default range of
+characters considered for encoding and for altering the visual
+representation.
+The additional character,
+.Fa nextc ,
+is only used when selecting the
+.Dv VIS_CSTYLE
+encoding format (explained below).
+.Pp
+The
+.Fn strvis
+and
+.Fn strvisx
+functions copy into
+.Fa dst
+a visual representation of
+the string
+.Fa src .
+The
+.Fn strvis
+function encodes characters from
+.Fa src
+up to the
+first
+.Dv NUL . 
+The
+.Fn strvisx
+function encodes exactly
+.Fa len
+characters from
+.Fa src
+(this
+is useful for encoding a block of data that may contain
+.Dv NUL Ns 's).
+Both forms
+.Dv NUL
+terminate
+.Fa dst .
+The size of
+.Fa dst
+must be four times the number
+of characters encoded from
+.Fa src
+(plus one for the
+.Dv NUL ) . 
+Both
+forms return the number of characters in dst (not including
+the trailing
+.Dv NUL ) . 
+.Pp
+The encoding is a unique, invertible representation comprised entirely of
+graphic characters; it can be decoded back into the original form using 
+the
+.Xr unvis 3
+or
+.Xr strunvis 3
+functions.
+.Pp
+There are two parameters that can be controlled: the range of
+characters that are encoded, and the type
+of representation used.  
+By default, all non-graphic characters.
+except space, tab, and newline are encoded.
+(See
+.Xr isgraph 3 . )
+The following flags
+alter this:
+.Bl -tag -width VIS_WHITEX
+.It Dv VIS_SP
+Also encode space.
+.It Dv VIS_TAB		
+Also encode tab.
+.It Dv VIS_NL
+Also encode newline.
+.It Dv VIS_WHITE	
+Synonym for
+.Dv VIS_SP
+\&|
+.Dv VIS_TAB
+\&|
+.Dv VIS_NL .
+.It Dv VIS_SAFE	
+Only encode "unsafe" characters.  Unsafe means control
+characters which may cause common terminals to perform
+unexpected functions.  Currently this form allows space,
+tab, newline, backspace, bell, and return - in addition
+to all graphic characters - unencoded. 
+.El
+.Pp
+There are three forms of encoding.
+All forms use the backslash character
+.Ql \e
+to introduce a special
+sequence; two backslashes are used to represent a real backslash.
+These are the visual formats:
+.Bl -tag -width VIS_CSTYLE
+.It (default)
+Use an
+.Ql M
+to represent meta characters (characters with the 8th
+bit set), and use caret
+.Ql ^
+to represent control characters see
+.Pf ( Xr iscntrl 3 ) .
+The following formats are used:
+.Bl -tag -width xxxxx
+.It Dv \e^C
+Represents the control character
+.Ql C .
+Spans characters
+.Ql \e000
+through
+.Ql \e037 ,
+and
+.Ql \e177
+(as
+.Ql \e^? ) .
+.It Dv \eM-C
+Represents character
+.Ql C
+with the 8th bit set.
+Spans characters
+.Ql \e241
+through
+.Ql \e376 .
+.It Dv \eM^C
+Represents control character
+.Ql C
+with the 8th bit set.
+Spans characters
+.Ql \e200
+through
+.Ql \e237 ,
+and
+.Ql \e377
+(as
+.Ql \eM^? ) .
+.It Dv \e040
+Represents
+.Tn ASCII
+space.
+.It Dv \e240
+Represents Meta-space.
+.El
+.Pp
+.It Dv VIS_CSTYLE
+Use C-style backslash sequences to represent standard non-printable
+characters.
+The following sequences are used to represent the indicated characters:
+.Bd -unfilled -offset indent
+.Li \ea Tn  - BEL No (007)
+.Li \eb Tn  - BS No (010)
+.Li \ef Tn  - NP No (014)

+When using this format, the nextc parameter is looked at to determine
+if a
+.Dv NUL
+character can be encoded as
+.Ql \e0
+instead of
+.Ql \e000 .
+If
+.Fa nextc
+is an octal digit, the latter representation is used to
+avoid ambiguity.
+.It Dv VIS_OCTAL
+Use a three digit octal sequence.  The form is
+.Ql \eddd
+where
+.Em d
+represents an octal digit.
+.El
+.Pp
+There is one additional flag,
+.Dv VIS_NOSLASH ,
+which inhibits the
+doubling of backslashes and the backslash before the default
+format (that is, control characters are represented by
+.Ql ^C
+and
+meta characters as
+.Ql M-C ) .
+With this flag set, the encoding is
+ambiguous and non-invertible.

+.Sh SYNOPSIS
+.Fn moncontrol "int mode"
+.Fn monstartup "u_long *lowpc" "u_long *highpc"
+.Sh DESCRIPTION
+An executable program compiled using the
+.Fl pg
+option to
+.Xr cc 1
+automatically includes calls to collect statistics for the
+.Xr gprof 1
+call-graph execution profiler.
+In typical operation, profiling begins at program startup
+and ends when the program calls exit.
+When the program exits, the profiling data are written to the file
+.Em gmon.out ,
+then
+.Xr gprof 1
+can be used to examine the results.
+.Pp
+.Fn moncontrol
+selectively controls profiling within a program.
+When the program starts, profiling begins.
+To stop the collection of histogram ticks and call counts use
+.Fn moncontrol 0 ;
+to resume the collection of histogram ticks and call counts use
+.Fn moncontrol 1 .
+This feature allows the cost of particular operations to be measured.
+Note that an output file will be produced on program exit
+regardless of the state of 
+.Fn moncontrol .
+.Pp
+Programs that are not loaded with
+.Fl pg
+may selectively collect profiling statistics by calling
+.Fn monstartup
+with the range of addresses to be profiled.
+.Fa lowpc
+and
+.Fa highpc
+specify the address range that is to be sampled;
+the lowest address sampled is that of
+.Fa lowpc
+and the highest is just below
+.Fa highpc .
+Only functions in that range that have been compiled with the 
+.Fl pg
+option to
+.Xr cc 1
+will appear in the call graph part of the output;
+however, all functions in that address range will
+have their execution time measured.
+Profiling begins on return from
+.Fn monstartup .

+.Fn ether_line "char *l" "struct ether_addr *e" "char *hostname"
+.Sh DESCRIPTION
+Ethernet addresses are represented by the 
+following structure:
+.Bd -literal -offset indent
+struct ether_addr {
+        u_char  ether_addr_octet[6];
+};
+.Ed
+.Pp
+The
+.Fn ether_ntoa
+function converts this structure into an ASCII string of the form
+``xx:xx:xx:xx:xx:xx'', consisting of 6 hexadecimal numbers separated
+by colons.  It returns a pointer to a static buffer that is reused for
+each call.
+The
+.Fn ether_aton
+converts an ASCII string of the same form and to a structure
+containing the 6 octets of the address.  It returns a pointer to a
+static structure that is reused for each call.
+.Pp
+The
+.Fn ether_ntohost
+and
+.Fn ether_hostton
+functions interrogate the data base mapping host names to Ethernet
+addresses,
+.Pa /etc/ethers .
+The
+.Fn ether_ntohost
+function looks up the given Ethernet address and writes the associated
+host name into the character buffer passed.
+The
+.Fn ether_hostton
+function looks up the given host name and writes the associated
+Ethernet address into the structure passed.  Both functions return
+zero if they find the requested host name or address, and -1 if not.
+Each call reads
+.Pa /etc/ethers 
+from the beginning; if a + appears alone on a line in the file, then
+.Fn ether_hostton
+will consult the
+.Pa ethers.byname
+YP map, and
+.Fn ether_ntohost
+will consult the
+.Pa ethers.byaddr
+YP map.
+.Pp
+The
+.Fn ether_line
+function parses a line from the
+.Pa /etc/ethers
+file and fills in the passed ``struct ether_addr'' and character
+buffer with the Ethernet address and host name on the line.  It
+returns zero if the line was successfully parsed and -1 if not.
+.Sh FILES
+.Bl -tag -width /etc/ethers -compact
+.It Pa /etc/ethers

+.Xr ethers 5
+.Sh HISTORY
+The
+.Fn ether_ntoa ,
+.Fn ether_aton ,
+.Fn ether_ntohost ,
+.Fn ether_hostton ,
+and
+.Fn ether_line
+functions were adopted from SunOS and appeared in
+NetBSD 0.9b.
+.Sh BUGS
+The data space used by these functions is static; if future use
+requires the data, it should be copied before any subsequent calls to
+these functions overwrite it.  There is no way to restrict how many
+character will be written into the host name buffer passed.  A very
+long line in
+.Pa /etc/ethers
+could overflow your buffer.

+.Sh DESCRIPTION
+The
+.Fn gethostbyname
+and
+.Fn gethostbyaddr
+functions
+each return a pointer to an object with the
+following structure describing an internet host
+referenced by name or by address, respectively.
+This structure contains either the information obtained from the name server,
+.Xr named 8 ,
+broken-out fields from a line in 
+.Pa /etc/hosts ,
+or database entries supplied by the
+.Xr yp 8
+system .
+If the local name server is not running these routines do a lookup in
+.Pa /etc/hosts .
+.Bd -literal
+struct	hostent {
+	char	*h_name;	/* official name of host */
+	char	**h_aliases;	/* alias list */
+	int	h_addrtype;	/* host address type */
+	int	h_length;	/* length of address */
+	char	**h_addr_list;	/* list of addresses from name server */
+};
+#define	h_addr  h_addr_list[0]	/* address, for backward compatibility */
+.Ed
+.Pp
+The members of this structure are:
+.Bl -tag -width h_addr_list
+.It Fa h_name
+Official name of the host.
+.It Fa h_aliases
+A zero terminated array of alternate names for the host.
+.It Fa h_addrtype
+The type of address being returned; currently always
+.Dv AF_INET .
+.It Fa h_length
+The length, in bytes, of the address.
+.It Fa h_addr_list
+A zero terminated array of network addresses for the host.
+Host addresses are returned in network byte order.
+.It Fa h_addr
+The first address in
+.Fa h_addr_list ;
+this is for backward compatibility.
+.Pp
+When using the nameserver,
+.Fn gethostbyname
+will search for the named host in the current domain and its parents
+unless the name ends in a dot.
+If the name contains no dot, and if the environment variable
+.Dq Ev HOSTALIASES
+contains the name of an alias file, the alias file will first be searched
+for an alias matching the input name.
+See
+.Xr hostname 7
+for the domain search procedure and the alias file format.
+.Pp
+The
+.Fn sethostent
+function
+may be used to request the use of a connected
+.Tn TCP
+socket for queries.
+If the
+.Fa stayopen
+flag is non-zero,
+this sets the option to send all queries to the name server using
+.Tn TCP
+and to retain the connection after each call to 
+.Fn gethostbyname
+or
+.Fn gethostbyaddr .
+Otherwise, queries are performed using
+.Tn UDP
+datagrams.
+.Pp
+The
+.Fn endhostent
+function
+closes the
+.Tn TCP
+connection.
+.Sh FILES
+.Bl -tag -width /etc/hosts -compact
+.It Pa /etc/hosts
+.El
+.Sh DIAGNOSTICS
+Error return status from 
+.Fn gethostbyname
+and
+.Fn gethostbyaddr
+is indicated by return of a null pointer.
+The external integer
+.Va h_errno
+may then be checked to see whether this is a temporary failure
+or an invalid or unknown host.
+The routine
+.Fn herror
+can be used to print an error message describing the failure.
+If its argument
+.Fa string
+is
+.Pf non Dv -NULL ,
+it is printed, followed by a colon and a space.
+The error message is printed with a trailing newline.
+.Pp
+The variable
+.Va h_errno
+can have the following values:
+.Bl -tag -width HOST_NOT_FOUND
+.It Dv HOST_NOT_FOUND
+No such host is known.
+.It Dv TRY_AGAIN
+This is usually a temporary error
+and means that the local server did not receive
+a response from an authoritative server.
+A retry at some later time may succeed.
+.It Dv NO_RECOVERY
+Some unexpected server failure was encountered.
+This is a non-recoverable error.
+.It Dv NO_DATA
+The requested name is valid but does not have an IP address; 
+this is not a temporary error.  
+This means that the name is known to the name server but there is no address
+associated with this name.
+Another type of request to the name server using this domain name
+will result in an answer;
+for example, a mail-forwarder may be registered for this domain.
+.El
+.Sh SEE ALSO
+.Xr resolver 3 ,
+.Xr hosts 5 ,
+.Xr hostname 7 ,
+.Xr named 8
+.Sh CAVEAT
+The
+.Fn gethostent
+function
+is defined, and
+.Fn sethostent
+and
+.Fn endhostent
+are redefined,
+when
+.Xr libc 3
+is built to use only the routines to lookup in
+.Pa /etc/hosts
+and not the name server.
+.Pp
+The
+.Fn gethostent
+function
+reads the next line of
+.Pa /etc/hosts ,
+opening the file if necessary.
+.Pp
+The
+.Fn sethostent
+function
+opens and/or rewinds the file
+.Pa /etc/hosts .
+If the
+.Fa stayopen
+argument is non-zero,
+the file will not be closed after each call to
+.Fn gethostbyname
+or
+.Fn gethostbyaddr .
+.Pp
+The
+.Fn endhostent
+function
+closes the file.
+.Sh HISTORY
+The
+.Fn herror
+function appeared in 
+.Bx 4.3 .
+The
+.Fn endhostent ,
+.Fn gethostbyaddr ,
+.Fn gethostbyname ,
+.Fn gethostent ,
+and
+.Fn sethostent
+functions appeared in
+.Bx 4.2 .
+.Sh BUGS
+These functions use static data storage;
+if the data is needed for future use, it should be
+copied before any subsequent calls overwrite it.
+Only the Internet
+address format is currently understood.

+.Fd #include <netdb.h>
+.Ft struct netent *
+.Fn getnetent 
+.Ft struct netent *
+.Fn getnetbyname "char *name"
+.Ft struct netent *
+.Fn getnetbyaddr "long net" "int type"
+.Fn setnetent "int stayopen"
+.Fn endnetent 
+.Sh DESCRIPTION
+The
+.Fn getnetent ,
+.Fn getnetbyname ,
+and
+.Fn getnetbyaddr
+functions
+each return a pointer to an object with the
+following structure
+containing the broken-out
+fields of a line in the network data base,
+.Pa /etc/networks .
+.Bd -literal -offset indent
+struct	netent {
+	char		*n_name;	/* official name of net */
+	char		**n_aliases;	/* alias list */
+	int		n_addrtype;	/* net number type */
+	unsigned long	n_net;		/* net number */
+};
+.Ed
+.Pp
+The members of this structure are:
+.Bl -tag -width n_addrtype
+.It Fa n_name
+The official name of the network.
+.It Fa n_aliases
+A zero terminated list of alternate names for the network.
+.It Fa n_addrtype
+The type of the network number returned; currently only AF_INET.
+.It Fa n_net
+The network number.  Network numbers are returned in machine byte
+order.
+.El
+.Pp
+The
+.Fn getnetent
+function
+reads the next line of the file, opening the file if necessary.
+.Pp
+The
+.Fn setnetent
+function
+opens and rewinds the file.  If the
+.Fa stayopen
+flag is non-zero,
+the net data base will not be closed after each call to 
+.Fn getnetbyname
+or
+.Fn getnetbyaddr .
+.Pp
+The
+.Fn endnetent
+function
+closes the file.
+.Pp
+The
+.Fn getnetbyname
+function
+and
+.Fn getnetbyaddr
+sequentially search from the beginning
+of the file until a matching
+net name or
+net address and type is found,
+or until
+.Dv EOF
+is encountered.
+Network numbers are supplied in host order.
+.Sh FILES
+.Bl -tag -width /etc/networks -compact
+.It Pa /etc/networks
+.El
+.Sh DIAGNOSTICS
+Null pointer
+(0) returned on
+.Dv EOF
+or error.
+.Sh SEE ALSO
+.Xr networks 5
+.Sh HISTORY
+The
+.Fn getnetent ,
+.Fn getnetbyaddr ,
+.Fn getnetbyname ,
+.Fn setnetent ,
+and
+.Fn endnetent
+functions appeared in 
+.Bx 4.2 .
+.Sh BUGS
+The data space used by
+these functions is static; if future use requires the data, it should be
+copied before any subsequent calls to these functions overwrite it.
+Only Internet network
+numbers are currently understood.
+Expecting network numbers to fit
+in no more than 32 bits is probably
+naive.

+.Ft unsigned long 
+.Fn inet_netof "struct in_addr in"
+.Sh DESCRIPTION
+The routines
+.Fn inet_aton ,
+.Fn inet_addr
+and
+.Fn inet_network
+interpret character strings representing
+numbers expressed in the Internet standard
+.Ql \&.
+notation.
+The
+.Fn inet_aton
+routine interprets the specified character string as an Internet address,
+placing the address into the structure provided.
+It returns 1 if the string was successfully interpreted,
+or 0 if the string is invalid.
+The
+.Fn inet_addr
+and
+.Fn inet_network
+functions return numbers suitable for use
+as Internet addresses and Internet network
+numbers, respectively.
+The routine
+.Fn inet_ntoa
+takes an Internet address and returns an
+.Tn ASCII
+string representing the address in
+.Ql \&.
+notation.  The routine
+.Fn inet_makeaddr
+takes an Internet network number and a local
+network address and constructs an Internet address
+from it.  The routines
+.Fn inet_netof
+and
+.Fn inet_lnaof
+break apart Internet host addresses, returning
+the network number and local network address part,
+respectively.
+.Pp
+All Internet addresses are returned in network
+order (bytes ordered from left to right).
+All network numbers and local address parts are
+returned as machine format integer values.
+.Sh INTERNET ADDRESSES
+Values specified using the
+.Ql \&.
+notation take one
+of the following forms:
+.Bd -literal -offset indent
+a.b.c.d
+a.b.c
+a.b
+a
+.Ed
+.Pp
+When four parts are specified, each is interpreted
+as a byte of data and assigned, from left to right,
+to the four bytes of an Internet address.  Note
+that when an Internet address is viewed as a 32-bit
+integer quantity on the
+.Tn VAX
+the bytes referred to
+above appear as
+.Dq Li d.c.b.a .
+That is,
+.Tn VAX
+bytes are
+ordered from right to left.
+.Pp
+When a three part address is specified, the last
+part is interpreted as a 16-bit quantity and placed
+in the right-most two bytes of the network address.
+This makes the three part address format convenient
+for specifying Class B network addresses as
+.Dq Li 128.net.host .
+.Pp
+When a two part address is supplied, the last part
+is interpreted as a 24-bit quantity and placed in
+the right most three bytes of the network address.
+This makes the two part address format convenient
+for specifying Class A network addresses as
+.Dq Li net.host .
+.Pp
+When only one part is given, the value is stored
+directly in the network address without any byte
+rearrangement.
+.Pp
+All numbers supplied as
+.Dq parts
+in a
+.Ql  \&.
+notation
+may be decimal, octal, or hexadecimal, as specified
+in the C language (i.e., a leading 0x or 0X implies
+hexadecimal; otherwise, a leading 0 implies octal;
+otherwise, the number is interpreted as decimal).
+.Sh DIAGNOSTICS
+The constant
+.Dv INADDR_NONE
+is returned by
+.Fn inet_addr
+and
+.Fn inet_network
+for malformed requests.
+.Sh SEE ALSO
+.Xr gethostbyname 3 ,
+.Xr getnetent 3 ,
+.Xr hosts 5 ,
+.Xr networks 5 ,
+.Sh HISTORY
+These
+functions appeared in 
+.Bx 4.2 .
+.Sh BUGS
+The value
+.Dv INADDR_NONE
+(0xffffffff) is a valid broadcast address, but
+.Fn inet_addr
+cannot return that value without indicating failure.
+The newer
+.Fn inet_aton
+function does not share this problem.
+The problem of host byte ordering versus network byte ordering is
+confusing.
+The string returned by
+.Fn inet_ntoa
+resides in a static memory area.
+.Pp
+Inet_addr should return a
+.Fa struct in_addr .

+.Dd June 4, 1993
+.Dt ISO_ADDR 3
+.Os
+.Sh NAME
+.Nm iso_addr ,
+.Nm iso_ntoa
+.Nd "elementary network address conversion routines for Open System Interconnection
+.Sh SYNOPSIS
+.Fd #include <sys/types.h>
+.Fd #include <netiso/iso.h>
+.Ft struct iso_addr *
+.Fn iso_addr "char *cp"
+.Ft char *
+.Fn iso_ntoa "struct iso_addr *isoa"
+.Sh DESCRIPTION
+The routine
+.Fn iso_addr
+interprets character strings representing
+.Tn OSI
+addresses, returning binary information suitable
+for use in system calls.
+The routine
+.Fn iso_ntoa
+takes
+.Tn OSI
+addresses and returns
+.Tn ASCII
+strings representing NSAPs (network service
+access points) in a
+notation inverse to that accepted by 
+.Fn iso_addr .
+.Pp
+Unfortunately, no universal standard exists for representing
+.Tn OSI
+network addresses.
+.Pp
+The format employed by
+.Fn iso_addr
+is a sequence of hexadecimal
+.Dq digits
+(optionally separated by periods),
+of the form:
+.Bd -filled -offset indent
+<hex digits>.<hex digits>.<hex digits>
+.Ed
+.Pp
+Each pair of hexadecimal digits represents a byte
+with the leading digit indicating the higher-ordered bits.
+A period following an even number of bytes has no
+effect (but may be used to increase legibility).
+A period following an odd number of bytes has the
+effect of causing the byte of address being translated
+to have its higher order bits filled with zeros.
+.Sh RETURN VALUES
+.Fn iso_ntoa
+always returns a null terminated string.
+.Fn iso_addr
+always returns a pointer to a struct iso_addr.
+(See
+.Sx BUGS . )
+.Sh SEE ALSO
+.Xr iso 4
+.Sh HISTORY
+The
+.Fn iso_addr
+and
+.Fn iso_ntoa
+functions appeared in 
+.Bx 4.3 Reno .
+.Sh BUGS
+The returned values
+reside in a static memory area.
+.Pp
+The function
+.Fn iso_addr
+should diagnose improperly formed input, and there should be an unambiguous
+way to recognize this.

+.Sh NAME
+.Nm link_addr ,
+.Nm link_ntoa
+.Nd elementary address specification routines for link level access
+.Sh SYNOPSIS
+.Fd #include <sys/types.h>
+.Fd #include <sys/socket.h>
+.Fd #include <net/if_dl.h>
+.Ft void
+.Fn link_addr "const char *addr" "struct sockaddr_dl *sdl"
+.Ft char *
+.Fn link_ntoa "const struct sockaddr_dl *sdl"
+.Sh DESCRIPTION
+The routine
+.Fn link_addr
+interprets character strings representing
+link-level addresses, returning binary information suitable
+for use in system calls.
+The routine
+.Fn link_ntoa
+takes
+a link-level
+address and returns an
+.Tn ASCII
+string representing some of the information present,
+including the link level address itself, and the interface name
+or number, if present.
+This facility is experimental and is
+still subject to change.
+.Pp
+For
+.Fn link_addr ,
+the string
+.Fa addr
+may contain
+an optional network interface identifier of the form
+.Dq "name unit-number" ,
+suitable for the first argument to
+.Xr ifconfig 4 ,
+followed in all cases by a colon and
+an interface address in the form of
+groups of hexadecimal digits
+separated by periods.
+Each group represents a byte of address;
+address bytes are filled left to right from
+low order bytes through high order bytes.
+.Pp
+.\" A regular expression may make this format clearer:
+.\" .Bd -literal -offset indent
+.\" ([a-z]+[0-9]+:)?[0-9a-f]+(\e.[0-9a-f]+)*
+.\" .Ed
+.\" .Pp
+Thus
+.Li le0:8.0.9.13.d.30
+represents an ethernet address
+to be transmitted on the first Lance ethernet interface.
+.Sh RETURN VALUES
+.Fn link_ntoa
+always returns a null terminated string.
+.Fn link_addr
+has no return value.
+(See
+.Sx BUGS . )
+.Sh SEE ALSO
+.Xr iso 4 ,
+.Sh HISTORY
+The
+.Fn link_addr
+and
+.Fn link_ntoa
+functions appeared in 
+.Bx 4.3 Reno  .
+.Sh BUGS
+The returned values for link_ntoa
+reside in a static memory area.
+.Pp
+The function
+.Fn link_addr
+should diagnose improperly formed input, and there should be an unambiguous
+way to recognize this.
+.Pp
+If the
+.Va sdl_len
+field of the link socket address
+.Fa sdl
+is 0,
+.Fn link_ntoa
+will not insert a colon before the interface address bytes.
+If this translated address is given to
+.Fn link_addr
+without inserting an initial colon,
+the latter will not interpret it correctly.

+The routine

+interprets character strings representing

+addresses, returning binary information suitable
+for use in system calls.
+The routine
+.Fn ns_ntoa
+takes
+.Tn XNS

+strings representing the address in a
+notation in common use in the Xerox Development Environment:
+.Bd -filled -offset indent
+<network number>.<host number>.<port number>
+.Ed
+.Pp
+Trailing zero fields are suppressed, and each number is printed in hexadecimal,
+in a format suitable for input to 
+.Fn ns_addr .
+Any fields lacking super-decimal digits will have a
+trailing
+.Ql H
+appended.
+.Pp
+Unfortunately, no universal standard exists for representing
+.Tn XNS
+addresses.
+An effort has been made to insure that
+.Fn ns_addr
+be compatible with most formats in common use.
+It will first separate an address into 1 to 3 fields using a single delimiter
+chosen from
+period
+.Ql \&. ,
+colon
+.Ql \&:
+or pound-sign
+.Ql \&# .
+Each field is then examined for byte separators (colon or period).
+If there are byte separators, each subfield separated is taken to be
+a small hexadecimal number, and the entirety is taken as a network-byte-ordered
+quantity to be zero extended in the high-network-order bytes.
+Next, the field is inspected for hyphens, in which case
+the field is assumed to be a number in decimal notation
+with hyphens separating the millenia.
+Next, the field is assumed to be a number:
+It is interpreted
+as hexadecimal if there is a leading
+.Ql 0x
+(as in C),
+a trailing
+.Ql H
+(as in Mesa), or there are any super-decimal digits present.
+It is interpreted as octal is there is a leading
+.Ql 0
+and there are no super-octal digits.
+Otherwise, it is converted as a decimal number.

+.Sh NAME
+.Nm rcmd ,
+.Nm rresvport ,
+.Nm iruserok ,
+.Nm ruserok
+.Nd routines for returning a stream to a remote command
+.Sh SYNOPSIS
+.Fd #include <unistd.h>
+.Ft int
+.Fn rcmd "char **ahost" "int inport" "const char *locuser" "const char *remuser" "const char *cmd" "int *fd2p"
+.Ft int
+.Fn rresvport "int *port"
+.Ft int
+.Fn iruserok "u_long raddr" "int superuser" "const char *ruser" "const char *luser"
+.Ft int
+.Fn ruserok "const char *rhost" "int superuser" "const char *ruser" "const char *luser"
+.Sh DESCRIPTION
+The
+.Fn rcmd
+function
+is used by the super-user to execute a command on
+a remote machine using an authentication scheme based
+on reserved port numbers.
+The
+.Fn rresvport
+function
+returns a descriptor to a socket
+with an address in the privileged port space.
+The
+.Fn iruserok
+and
+.Fn ruserok
+functions are used by servers
+to authenticate clients requesting service with
+.Fn rcmd .
+All four functions are present in the same file and are used
+by the
+.Xr rshd 8
+server (among others).
+.Pp
+The
+.Fn rcmd
+function
+looks up the host
+.Fa *ahost
+using
+.Xr gethostbyname 3 ,
+returning \-1 if the host does not exist.
+Otherwise
+.Fa *ahost
+is set to the standard name of the host
+and a connection is established to a server
+residing at the well-known Internet port
+.Fa inport .
+.Pp
+If the connection succeeds,
+a socket in the Internet domain of type
+.Dv SOCK_STREAM
+is returned to the caller, and given to the remote
+command as 
+.Em stdin
+and
+.Em stdout .
+If
+.Fa fd2p
+is non-zero, then an auxiliary channel to a control
+process will be set up, and a descriptor for it will be placed
+in
+.Fa *fd2p .
+The control process will return diagnostic
+output from the command (unit 2) on this channel, and will also
+accept bytes on this channel as being
+.Tn UNIX
+signal numbers, to be
+forwarded to the process group of the command.
+If
+.Fa fd2p
+is 0, then the 
+.Em stderr
+(unit 2 of the remote
+command) will be made the same as the 
+.Em stdout
+and no
+provision is made for sending arbitrary signals to the remote process,
+although you may be able to get its attention by using out-of-band data.
+.Pp
+The protocol is described in detail in
+.Xr rshd 8 .
+.Pp
+The
+.Fn rresvport
+function is used to obtain a socket with a privileged
+address bound to it.  This socket is suitable for use
+by 
+.Fn rcmd
+and several other functions.  Privileged Internet ports are those
+in the range 0 to 1023.  Only the super-user
+is allowed to bind an address of this sort to a socket.
+.Pp
+The
+.Fn iruserok
+and
+.Fn ruserok
+functions take a remote host's IP address or name, respectively,
+two user names and a flag indicating whether the local user's
+name is that of the super-user.
+Then, if the user is
+.Em NOT
+the super-user, it checks the
+.Pa /etc/hosts.equiv
+file.
+If that lookup is not done, or is unsuccessful, the
+.Pa .rhosts
+in the local user's home directory is checked to see if the request for
+service is allowed.
+.Pp
+If this file does not exist, is not a regular file, is owned by anyone
+other than the user or the super-user, or is writeable by anyone other
+than the owner, the check automatically fails.
+Zero is returned if the machine name is listed in the
+.Dq Pa hosts.equiv
+file, or the host and remote user name are found in the
+.Dq Pa .rhosts
+file; otherwise
+.Fn iruserok
+and
+.Fn ruserok
+return \-1.
+If the local domain (as obtained from
+.Xr gethostname 2 )
+is the same as the remote domain, only the machine name need be specified.
+.Pp
+If the IP address of the remote host is known,
+.Fn iruserok
+should be used in preference to
+.Fn ruserok ,
+as it does not require trusting the DNS server for the remote host's domain.
+.Sh DIAGNOSTICS
+The
+.Fn rcmd
+function
+returns a valid socket descriptor on success.
+It returns \-1 on error and prints a diagnostic message on the standard error.
+.Pp
+The
+.Fn rresvport
+function
+returns a valid, bound socket descriptor on success.
+It returns \-1 on error with the global value
+.Va errno
+set according to the reason for failure.
+The error code
+.Dv EAGAIN
+is overloaded to mean ``All network ports in use.''

+.Sh DESCRIPTION
+These routines are used for making, sending and interpreting
+query and reply messages with Internet domain name servers.
+.Pp
+Global configuration and state information that is used by the
+resolver routines is kept in the structure
+.Em _res .
+Most of the values have reasonable defaults and can be ignored.
+Options
+stored in
+.Em _res.options
+are defined in
+.Pa resolv.h
+and are as follows.
+Options are stored as a simple bit mask containing the bitwise ``or''
+of the options enabled.
+.Bl -tag -width RES_DEFNAMES
+.It Dv RES_INIT
+True if the initial name server address and default domain name are
+initialized (i.e.,
+.Fn res_init
+has been called).
+.It Dv RES_DEBUG
+Print debugging messages.
+.It Dv RES_AAONLY
+Accept authoritative answers only.
+With this option,
+.Fn res_send
+should continue until it finds an authoritative answer or finds an error.
+Currently this is not implemented.
+.It Dv RES_USEVC
+Use
+.Tn TCP
+connections for queries instead of
+.Tn UDP
+datagrams.
+.It Dv RES_STAYOPEN
+Used with
+.Dv RES_USEVC
+to keep the
+.Tn TCP
+connection open between
+queries.
+This is useful only in programs that regularly do many queries.
+.Tn UDP
+should be the normal mode used.
+.It Dv RES_IGNTC
+Unused currently (ignore truncation errors, i.e., don't retry with
+.Tn TCP ) .
+.It Dv RES_RECURSE
+Set the recursion-desired bit in queries.
+This is the default.
+.Pf ( Fn res_send
+does not do iterative queries and expects the name server
+to handle recursion.)
+.It Dv RES_DEFNAMES
+If set,
+.Fn res_search
+will append the default domain name to single-component names
+(those that do not contain a dot).
+This option is enabled by default.
+.It Dv RES_DNSRCH
+If this option is set,
+.Fn res_search
+will search for host names in the current domain and in parent domains; see
+.Xr hostname 7 .
+This is used by the standard host lookup routine
+.Xr gethostbyname 3 .
+This option is enabled by default.
+.El
+.Pp
+The
+.Fn res_init
+routine
+reads the configuration file (if any; see
+.Xr resolv.conf 5 )
+to get the default domain name,
+search list and
+the Internet address of the local name server(s).
+If no server is configured, the host running
+the resolver is tried.
+The current domain name is defined by the hostname
+if not specified in the configuration file;
+it can be overridden by the environment variable
+.Ev LOCALDOMAIN .
+This environment variable may contain several blank-separated
+tokens if you wish to override the
+.Fa search list
+on a per-process basis.
+This is similar to the
+.Fa search
+command in the configuration file.
+Another environment variable
+.Ev RES_OPTIONS
+can be set to override certain internal resolver options which
+are otherwise set by changing fields in the
+.Fa _res
+structure or are inherited from the configuration file's
+.Fa options
+command.
+The syntax of the
+.Ev RES_OPTIONS
+environment variable is explained in
+.Xr resolv.conf 5 .
+Initialization normally occurs on the first call
+to one of the following routines.
+.Pp
+The
+.Fn res_query
+function provides an interface to the server query mechanism.
+It constructs a query, sends it to the local server,
+awaits a response, and makes preliminary checks on the reply.
+The query requests information of the specified
+.Fa type
+and
+.Fa class
+for the specified fully-qualified domain name
+.Fa dname .
+The reply message is left in the
+.Fa answer
+buffer with length
+.Fa anslen
+supplied by the caller.
+.Pp
+The
+.Fn res_search
+routine makes a query and awaits a response like
+.Fn res_query ,
+but in addition, it implements the default and search rules
+controlled by the
+.Dv RES_DEFNAMES
+and
+.Dv RES_DNSRCH
+options.
+It returns the first successful reply.
+.Pp
+The remaining routines are lower-level routines used by
+.Fn res_query .
+The
+.Fn res_mkquery
+function
+constructs a standard query message and places it in
+.Fa buf .
+It returns the size of the query, or \-1 if the query is
+larger than
+.Fa buflen .
+The query type
+.Fa op
+is usually
+.Dv QUERY ,
+but can be any of the query types defined in
+.Aq Pa arpa/nameser.h .
+The domain name for the query is given by
+.Fa dname .
+.Fa Newrr
+is currently unused but is intended for making update messages.
+.Pp
+The
+.Fn res_send
+routine
+sends a pre-formatted query and returns an answer.
+It will call
+.Fn res_init
+if
+.Dv RES_INIT
+is not set, send the query to the local name server, and
+handle timeouts and retries.
+The length of the reply message is returned, or
+\-1 if there were errors.
+.Pp
+The
+.Fn dn_comp
+function
+compresses the domain name
+.Fa exp_dn
+and stores it in
+.Fa comp_dn .
+The size of the compressed name is returned or \-1 if there were errors.
+The size of the array pointed to by
+.Fa comp_dn
+is given by
+.Fa length .
+The compression uses
+an array of pointers
+.Fa dnptrs
+to previously-compressed names in the current message.
+The first pointer points to
+to the beginning of the message and the list ends with
+.Dv NULL .
+The limit to the array is specified by
+.Fa lastdnptr .
+A side effect of
+.Fn dn_comp
+is to update the list of pointers for
+labels inserted into the message
+as the name is compressed.
+If
+.Em dnptr
+is
+.Dv NULL, names are not compressed.
+If
+.Fa lastdnptr
+is
+.Dv NULL ,
+the list of labels is not updated.
+.Pp
+The
+.Fn dn_expand
+entry
+expands the compressed domain name
+.Fa comp_dn
+to a full domain name
+The compressed name is contained in a query or reply message;
+.Fa msg
+is a pointer to the beginning of the message.
+The uncompressed name is placed in the buffer indicated by
+.Fa exp_dn
+which is of size
+.Fa length .
+The size of compressed name is returned or \-1 if there was an error.

+ * Multiply two quads.
+ *
+ * Our algorithm is based on the following.  Split incoming quad values
+ * u and v (where u,v >= 0) into
+ *
+ *	u = 2^n u1  *  u0	(n = number of bits in `u_long', usu. 32)
+ *
+ * and 
+ *
+ *	v = 2^n v1  *  v0
+ *
+ * Then
+ *
+ *	uv = 2^2n u1 v1  +  2^n u1 v0  +  2^n v1 u0  +  u0 v0
+ *	   = 2^2n u1 v1  +     2^n (u1 v0 + v1 u0)   +  u0 v0
+ *
+ * Now add 2^n u1 v1 to the first term and subtract it from the middle,
+ * and add 2^n u0 v0 to the last term and subtract it from the middle.
+ * This gives:
+ *
+ *	uv = (2^2n + 2^n) (u1 v1)  +
+ *	         (2^n)    (u1 v0 - u1 v1 + u0 v1 - u0 v0)  +
+ *	       (2^n + 1)  (u0 v0)
+ *
+ * Factoring the middle a bit gives us:
+ *
+ *	uv = (2^2n + 2^n) (u1 v1)  +			[u1v1 = high]
+ *		 (2^n)    (u1 - u0) (v0 - v1)  +	[(u1-u0)... = mid]
+ *	       (2^n + 1)  (u0 v0)			[u0v0 = low]
+ *
+ * The terms (u1 v1), (u1 - u0) (v0 - v1), and (u0 v0) can all be done
+ * in just half the precision of the original.  (Note that either or both
+ * of (u1 - u0) or (v0 - v1) may be negative.)
+ *
+ * This algorithm is from Knuth vol. 2 (2nd ed), section 4.3.3, p. 278.
+ *
+ * Since C does not give us a `long * long = quad' operator, we split
+ * our input quads into two longs, then split the two longs into two
+ * shorts.  We can then calculate `short * short = long' in native
+ * arithmetic.
+ *
+ * Our product should, strictly speaking, be a `long quad', with 128
+ * bits, but we are going to discard the upper 64.  In other words,
+ * we are not interested in uv, but rather in (uv mod 2^2n).  This
+ * makes some of the terms above vanish, and we get:
+ *
+ *	(2^n)(high) + (2^n)(mid) + (2^n + 1)(low)
+ *
+ * or
+ *
+ *	(2^n)(high + mid + low) + low
+ *
+ * Furthermore, `high' and `mid' can be computed mod 2^n, as any factor
+ * of 2^n in either one will also vanish.  Only `low' need be computed
+ * mod 2^2n, and only because of the final term above.

+# @(#)WHATSNEW	8.3 (Berkeley) 3/18/94
+
+New in alpha3.4:  The complex bug alluded to below has been fixed (in a
+slightly kludgey temporary way that may hurt efficiency a bit; this is
+another "get it out the door for 4.4" release).  The tests at the end of
+the tests file have accordingly been uncommented.  The primary sign of
+the bug was that something like a?b matching ab matched b rather than ab.
+(The bug was essentially specific to this exact situation, else it would
+have shown up earlier.)
+
+New in alpha3.3:  The definition of word boundaries has been altered
+slightly, to more closely match the usual programming notion that "_"
+is an alphabetic.  Stuff used for pre-ANSI systems is now in a subdir,
+and the makefile no longer alludes to it in mysterious ways.  The
+makefile has generally been cleaned up some.  Fixes have been made
+(again!) so that the regression test will run without -DREDEBUG, at
+the cost of weaker checking.  A workaround for a bug in some folks'
+<assert.h> has been added.  And some more things have been added to
+tests, including a couple right at the end which are commented out
+because the code currently flunks them (complex bug; fix coming).
+Plus the usual minor cleanup.
+
+New in alpha3.2:  Assorted bits of cleanup and portability improvement
+(the development base is now a BSDI system using GCC instead of an ancient
+Sun system, and the newer compiler exposed some glitches).  Fix for a
+serious bug that affected REs using many [] (including REG_ICASE REs
+because of the way they are implemented), *sometimes*, depending on
+memory-allocation patterns.  The header-file prototypes no longer name
+the parameters, avoiding possible name conflicts.  The possibility that
+some clot has defined CHAR_MIN as (say) `-128' instead of `(-128)' is
+now handled gracefully.  "uchar" is no longer used as an internal type
+name (too many people have the same idea).  Still the same old lousy
+performance, alas.
+
+New in alpha3.1:  Basically nothing, this release is just a bookkeeping
+convenience.  Stay tuned.
+
+New in alpha3.0:  Performance is no better, alas, but some fixes have been
+made and some functionality has been added.  (This is basically the "get
+it out the door in time for 4.4" release.)  One bug fix:  regfree() didn't
+free the main internal structure (how embarrassing).  It is now possible
+to put NULs in either the RE or the target string, using (resp.) a new
+REG_PEND flag and the old REG_STARTEND flag.  The REG_NOSPEC flag to
+regcomp() makes all characters ordinary, so you can match a literal
+string easily (this will become more useful when performance improves!).
+There are now primitives to match beginnings and ends of words, although
+the syntax is disgusting and so is the implementation.  The REG_ATOI
+debugging interface has changed a bit.  And there has been considerable
+internal cleanup of various kinds.
+
+New in alpha2.3:  Split change list out of README, and moved flags notes
+into Makefile.  Macro-ized the name of regex(7) in regex(3), since it has
+to change for 4.4BSD.  Cleanup work in engine.c, and some new regression
+tests to catch tricky cases thereof.
+
+New in alpha2.2:  Out-of-date manpages updated.  Regerror() acquires two
+small extensions -- REG_ITOA and REG_ATOI -- which avoid debugging kludges
+in my own test program and might be useful to others for similar purposes.
+The regression test will now compile (and run) without REDEBUG.  The
+BRE \$ bug is fixed.  Most uses of "uchar" are gone; it's all chars now.
+Char/uchar parameters are now written int/unsigned, to avoid possible
+portability problems with unpromoted parameters.  Some unsigned casts have
+been introduced to minimize portability problems with shifting into sign
+bits.
+
+New in alpha2.1:  Lots of little stuff, cleanup and fixes.  The one big
+thing is that regex.h is now generated, using mkh, rather than being
+supplied in the distribution; due to circularities in dependencies,
+you have to build regex.h explicitly by "make h".  The two known bugs
+have been fixed (and the regression test now checks for them), as has a
+problem with assertions not being suppressed in the absence of REDEBUG.
+No performance work yet.
+
+New in alpha2:  Backslash-anything is an ordinary character, not an
+error (except, of course, for the handful of backslashed metacharacters
+in BREs), which should reduce script breakage.  The regression test
+checks *where* null strings are supposed to match, and has generally
+been tightened up somewhat.  Small bug fixes in parameter passing (not
+harmful, but technically errors) and some other areas.  Debugging
+invoked by defining REDEBUG rather than not defining NDEBUG.
+
+New in alpha+3:  full prototyping for internal routines, using a little
+helper program, mkh, which extracts prototypes given in stylized comments.
+More minor cleanup.  Buglet fix:  it's CHAR_BIT, not CHAR_BITS.  Simple
+pre-screening of input when a literal string is known to be part of the
+RE; this does wonders for performance.
+
+New in alpha+2:  minor bits of cleanup.  Notably, the number "32" for the
+word width isn't hardwired into regexec.c any more, the public header
+file prototypes the functions if __STDC__ is defined, and some small typos
+in the manpages have been fixed.
+
+New in alpha+1:  improvements to the manual pages, and an important
+extension, the REG_STARTEND option to regexec().

+.TH RE_FORMAT 7 "March 20, 1994"
+.SH NAME
+re_format \- POSIX 1003.2 regular expressions
+.SH DESCRIPTION
+Regular expressions (``RE''s),
+as defined in POSIX 1003.2, come in two forms:
+modern REs (roughly those of
+.IR egrep ;
+1003.2 calls these ``extended'' REs)
+and obsolete REs (roughly those of
+.IR ed ;
+1003.2 ``basic'' REs).
+Obsolete REs mostly exist for backward compatibility in some old programs;
+they will be discussed at the end.
+1003.2 leaves some aspects of RE syntax and semantics open;
+`\(dg' marks decisions on these aspects that
+may not be fully portable to other 1003.2 implementations.
+.PP
+A (modern) RE is one\(dg or more non-empty\(dg \fIbranches\fR,
+separated by `|'.
+It matches anything that matches one of the branches.
+.PP
+A branch is one\(dg or more \fIpieces\fR, concatenated.
+It matches a match for the first, followed by a match for the second, etc.
+.PP
+A piece is an \fIatom\fR possibly followed
+by a single\(dg `*', `+', `?', or \fIbound\fR.
+An atom followed by `*' matches a sequence of 0 or more matches of the atom.
+An atom followed by `+' matches a sequence of 1 or more matches of the atom.
+An atom followed by `?' matches a sequence of 0 or 1 matches of the atom.
+.PP
+A \fIbound\fR is `{' followed by an unsigned decimal integer,
+possibly followed by `,'
+possibly followed by another unsigned decimal integer,
+always followed by `}'.
+The integers must lie between 0 and RE_DUP_MAX (255\(dg) inclusive,
+and if there are two of them, the first may not exceed the second.
+An atom followed by a bound containing one integer \fIi\fR
+and no comma matches
+a sequence of exactly \fIi\fR matches of the atom.
+An atom followed by a bound
+containing one integer \fIi\fR and a comma matches
+a sequence of \fIi\fR or more matches of the atom.
+An atom followed by a bound
+containing two integers \fIi\fR and \fIj\fR matches
+a sequence of \fIi\fR through \fIj\fR (inclusive) matches of the atom.
+.PP
+An atom is a regular expression enclosed in `()' (matching a match for the
+regular expression),
+an empty set of `()' (matching the null string)\(dg,
+a \fIbracket expression\fR (see below), `.'
+(matching any single character), `^' (matching the null string at the
+beginning of a line), `$' (matching the null string at the
+end of a line), a `\e' followed by one of the characters
+`^.[$()|*+?{\e'
+(matching that character taken as an ordinary character),
+a `\e' followed by any other character\(dg
+(matching that character taken as an ordinary character,
+as if the `\e' had not been present\(dg),
+or a single character with no other significance (matching that character).
+A `{' followed by a character other than a digit is an ordinary
+character, not the beginning of a bound\(dg.
+It is illegal to end an RE with `\e'.
+.PP
+A \fIbracket expression\fR is a list of characters enclosed in `[]'.
+It normally matches any single character from the list (but see below).
+If the list begins with `^',
+it matches any single character
+(but see below) \fInot\fR from the rest of the list.
+If two characters in the list are separated by `\-', this is shorthand
+for the full \fIrange\fR of characters between those two (inclusive) in the
+collating sequence,
+e.g. `[0-9]' in ASCII matches any decimal digit.
+It is illegal\(dg for two ranges to share an
+endpoint, e.g. `a-c-e'.
+Ranges are very collating-sequence-dependent,
+and portable programs should avoid relying on them.
+.PP
+To include a literal `]' in the list, make it the first character
+(following a possible `^').
+To include a literal `\-', make it the first or last character,
+or the second endpoint of a range.
+To use a literal `\-' as the first endpoint of a range,
+enclose it in `[.' and `.]' to make it a collating element (see below).
+With the exception of these and some combinations using `[' (see next
+paragraphs), all other special characters, including `\e', lose their
+special significance within a bracket expression.
+.PP
+Within a bracket expression, a collating element (a character,
+a multi-character sequence that collates as if it were a single character,
+or a collating-sequence name for either)
+enclosed in `[.' and `.]' stands for the
+sequence of characters of that collating element.
+The sequence is a single element of the bracket expression's list.
+A bracket expression containing a multi-character collating element 
+can thus match more than one character,
+e.g. if the collating sequence includes a `ch' collating element,
+then the RE `[[.ch.]]*c' matches the first five characters
+of `chchcc'.
+.PP
+Within a bracket expression, a collating element enclosed in `[=' and
+`=]' is an equivalence class, standing for the sequences of characters
+of all collating elements equivalent to that one, including itself.
+(If there are no other equivalent collating elements,
+the treatment is as if the enclosing delimiters were `[.' and `.]'.)
+For example, if o and \o'o^' are the members of an equivalence class,
+then `[[=o=]]', `[[=\o'o^'=]]', and `[o\o'o^']' are all synonymous.
+An equivalence class may not\(dg be an endpoint
+of a range.
+.PP
+Within a bracket expression, the name of a \fIcharacter class\fR enclosed
+in `[:' and `:]' stands for the list of all characters belonging to that
+class.
+Standard character class names are:
+.PP
+.RS
+.nf
+.ta 3c 6c 9c
+alnum	digit	punct
+alpha	graph	space
+blank	lower	upper
+cntrl	print	xdigit
+.fi
+.RE
+.PP
+These stand for the character classes defined in
+.IR ctype (3).
+A locale may provide others.
+A character class may not be used as an endpoint of a range.
+.PP
+There are two special cases\(dg of bracket expressions:
+the bracket expressions `[[:<:]]' and `[[:>:]]' match the null string at
+the beginning and end of a word respectively.
+A word is defined as a sequence of
+word characters
+which is neither preceded nor followed by
+word characters.
+A word character is an
+.I alnum
+character (as defined by
+.IR ctype (3))
+or an underscore.
+This is an extension,
+compatible with but not specified by POSIX 1003.2,
+and should be used with
+caution in software intended to be portable to other systems.
+.PP
+In the event that an RE could match more than one substring of a given
+string,
+the RE matches the one starting earliest in the string.
+If the RE could match more than one substring starting at that point,
+it matches the longest.
+Subexpressions also match the longest possible substrings, subject to
+the constraint that the whole match be as long as possible,
+with subexpressions starting earlier in the RE taking priority over
+ones starting later.
+Note that higher-level subexpressions thus take priority over
+their lower-level component subexpressions.
+.PP
+Match lengths are measured in characters, not collating elements.
+A null string is considered longer than no match at all.
+For example,
+`bb*' matches the three middle characters of `abbbc',
+`(wee|week)(knights|nights)' matches all ten characters of `weeknights',
+when `(.*).*' is matched against `abc' the parenthesized subexpression
+matches all three characters, and
+when `(a*)*' is matched against `bc' both the whole RE and the parenthesized
+subexpression match the null string.
+.PP
+If case-independent matching is specified,
+the effect is much as if all case distinctions had vanished from the
+alphabet.
+When an alphabetic that exists in multiple cases appears as an
+ordinary character outside a bracket expression, it is effectively
+transformed into a bracket expression containing both cases,
+e.g. `x' becomes `[xX]'.
+When it appears inside a bracket expression, all case counterparts
+of it are added to the bracket expression, so that (e.g.) `[x]'
+becomes `[xX]' and `[^x]' becomes `[^xX]'.
+.PP
+No particular limit is imposed on the length of REs\(dg.
+Programs intended to be portable should not employ REs longer
+than 256 bytes,
+as an implementation can refuse to accept such REs and remain
+POSIX-compliant.
+.PP
+Obsolete (``basic'') regular expressions differ in several respects.
+`|', `+', and `?' are ordinary characters and there is no equivalent
+for their functionality.
+The delimiters for bounds are `\e{' and `\e}',
+with `{' and `}' by themselves ordinary characters.
+The parentheses for nested subexpressions are `\e(' and `\e)',
+with `(' and `)' by themselves ordinary characters.
+`^' is an ordinary character except at the beginning of the
+RE or\(dg the beginning of a parenthesized subexpression,
+`$' is an ordinary character except at the end of the
+RE or\(dg the end of a parenthesized subexpression,
+and `*' is an ordinary character if it appears at the beginning of the
+RE or the beginning of a parenthesized subexpression
+(after a possible leading `^').
+Finally, there is one new type of atom, a \fIback reference\fR:
+`\e' followed by a non-zero decimal digit \fId\fR
+matches the same sequence of characters
+matched by the \fId\fRth parenthesized subexpression
+(numbering subexpressions by the positions of their opening parentheses,
+left to right),
+so that (e.g.) `\e([bc]\e)\e1' matches `bb' or `cc' but not `bc'.
+.SH SEE ALSO
+regex(3)
+.PP
+POSIX 1003.2, section 2.8 (Regular Expression Notation).
+.SH BUGS
+Having two kinds of REs is a botch.
+.PP
+The current 1003.2 spec says that `)' is an ordinary character in
+the absence of an unmatched `(';
+this was an unintentional result of a wording error,
+and change is likely.
+Avoid relying on it.
+.PP
+Back references are a dreadful botch,
+posing major problems for efficient implementations.
+They are also somewhat vaguely defined
+(does
+`a\e(\e(b\e)*\e2\e)*d' match `abbbd'?).
+Avoid using them.
+.PP
+1003.2's specification of case-independent matching is vague.
+The ``one case implies all cases'' definition given above
+is current consensus among implementors as to the right interpretation.
+.PP
+The syntax for word boundaries is incredibly ugly.

+.SH DESCRIPTION
+These routines implement POSIX 1003.2 regular expressions (``RE''s);
+see
+.ZR .
+.I Regcomp
+compiles an RE written as a string into an internal form,
+.I regexec
+matches that internal form against a string and reports results,
+.I regerror
+transforms error codes from either into human-readable messages,
+and
+.I regfree
+frees any dynamically-allocated storage used by the internal form
+of an RE.
+.PP
+The header
+.I <regex.h>
+declares two structure types,
+.I regex_t
+and
+.IR regmatch_t ,
+the former for compiled internal forms and the latter for match reporting.
+It also declares the four functions,
+a type
+.IR regoff_t ,
+and a number of constants with names starting with ``REG_''.
+.PP
+.I Regcomp
+compiles the regular expression contained in the
+.I pattern
+string,
+subject to the flags in
+.IR cflags ,
+and places the results in the
+.I regex_t
+structure pointed to by
+.IR preg .
+.I Cflags
+is the bitwise OR of zero or more of the following flags:
+.IP REG_EXTENDED \w'REG_EXTENDED'u+2n
+Compile modern (``extended'') REs,
+rather than the obsolete (``basic'') REs that
+are the default.
+.IP REG_BASIC
+This is a synonym for 0,
+provided as a counterpart to REG_EXTENDED to improve readability.
+.IP REG_NOSPEC
+Compile with recognition of all special characters turned off.
+All characters are thus considered ordinary,
+so the ``RE'' is a literal string.
+This is an extension,
+compatible with but not specified by POSIX 1003.2,
+and should be used with
+caution in software intended to be portable to other systems.
+REG_EXTENDED and REG_NOSPEC may not be used
+in the same call to
+.IR regcomp .
+.IP REG_ICASE
+Compile for matching that ignores upper/lower case distinctions.
+See
+.ZR .
+.IP REG_NOSUB
+Compile for matching that need only report success or failure,
+not what was matched.
+.IP REG_NEWLINE
+Compile for newline-sensitive matching.
+By default, newline is a completely ordinary character with no special
+meaning in either REs or strings.
+With this flag,
+`[^' bracket expressions and `.' never match newline,
+a `^' anchor matches the null string after any newline in the string
+in addition to its normal function,
+and the `$' anchor matches the null string before any newline in the
+string in addition to its normal function.
+.IP REG_PEND
+The regular expression ends,
+not at the first NUL,
+but just before the character pointed to by the
+.I re_endp
+member of the structure pointed to by
+.IR preg .
+The
+.I re_endp
+member is of type
+.IR const\ char\ * .
+This flag permits inclusion of NULs in the RE;
+they are considered ordinary characters.
+This is an extension,
+compatible with but not specified by POSIX 1003.2,
+and should be used with
+caution in software intended to be portable to other systems.
+.PP
+When successful,
+.I regcomp
+returns 0 and fills in the structure pointed to by
+.IR preg .
+One member of that structure
+(other than
+.IR re_endp )
+is publicized:
+.IR re_nsub ,
+of type
+.IR size_t ,
+contains the number of parenthesized subexpressions within the RE
+(except that the value of this member is undefined if the
+REG_NOSUB flag was used).
+If
+.I regcomp
+fails, it returns a non-zero error code;
+see DIAGNOSTICS.
+.PP
+.I Regexec
+matches the compiled RE pointed to by
+.I preg
+against the
+.IR string ,
+subject to the flags in
+.IR eflags ,
+and reports results using
+.IR nmatch ,
+.IR pmatch ,
+and the returned value.
+The RE must have been compiled by a previous invocation of
+.IR regcomp .
+The compiled form is not altered during execution of
+.IR regexec ,
+so a single compiled RE can be used simultaneously by multiple threads.
+.PP
+By default,
+the NUL-terminated string pointed to by
+.I string
+is considered to be the text of an entire line, minus any terminating
+newline.
+The
+.I eflags
+argument is the bitwise OR of zero or more of the following flags:
+.IP REG_NOTBOL \w'REG_STARTEND'u+2n
+The first character of
+the string
+is not the beginning of a line, so the `^' anchor should not match before it.
+This does not affect the behavior of newlines under REG_NEWLINE.
+.IP REG_NOTEOL
+The NUL terminating
+the string
+does not end a line, so the `$' anchor should not match before it.
+This does not affect the behavior of newlines under REG_NEWLINE.
+.IP REG_STARTEND
+The string is considered to start at
+\fIstring\fR\ + \fIpmatch\fR[0].\fIrm_so\fR
+and to have a terminating NUL located at
+\fIstring\fR\ + \fIpmatch\fR[0].\fIrm_eo\fR
+(there need not actually be a NUL at that location),
+regardless of the value of
+.IR nmatch .
+See below for the definition of
+.IR pmatch
+and
+.IR nmatch .
+This is an extension,
+compatible with but not specified by POSIX 1003.2,
+and should be used with
+caution in software intended to be portable to other systems.
+Note that a non-zero \fIrm_so\fR does not imply REG_NOTBOL;
+REG_STARTEND affects only the location of the string,
+not how it is matched.
+.PP
+See
+.ZR
+for a discussion of what is matched in situations where an RE or a
+portion thereof could match any of several substrings of
+.IR string .
+.PP
+Normally,
+.I regexec
+returns 0 for success and the non-zero code REG_NOMATCH for failure.
+Other non-zero error codes may be returned in exceptional situations;
+see DIAGNOSTICS.
+.PP
+If REG_NOSUB was specified in the compilation of the RE,
+or if
+.I nmatch
+is 0,
+.I regexec
+ignores the
+.I pmatch
+argument (but see below for the case where REG_STARTEND is specified).
+Otherwise,
+.I pmatch
+points to an array of
+.I nmatch
+structures of type
+.IR regmatch_t .
+Such a structure has at least the members
+.I rm_so
+and
+.IR rm_eo ,
+both of type
+.I regoff_t
+(a signed arithmetic type at least as large as an
+.I off_t
+and a
+.IR ssize_t ),
+containing respectively the offset of the first character of a substring
+and the offset of the first character after the end of the substring.
+Offsets are measured from the beginning of the
+.I string
+argument given to
+.IR regexec .
+An empty substring is denoted by equal offsets,
+both indicating the character following the empty substring.
+.PP
+The 0th member of the
+.I pmatch
+array is filled in to indicate what substring of
+.I string
+was matched by the entire RE.
+Remaining members report what substring was matched by parenthesized
+subexpressions within the RE;
+member
+.I i
+reports subexpression
+.IR i ,
+with subexpressions counted (starting at 1) by the order of their opening
+parentheses in the RE, left to right.
+Unused entries in the array\(emcorresponding either to subexpressions that
+did not participate in the match at all, or to subexpressions that do not
+exist in the RE (that is, \fIi\fR\ > \fIpreg\fR\->\fIre_nsub\fR)\(emhave both
+.I rm_so
+and
+.I rm_eo
+set to \-1.
+If a subexpression participated in the match several times,
+the reported substring is the last one it matched.
+(Note, as an example in particular, that when the RE `(b*)+' matches `bbb',
+the parenthesized subexpression matches each of the three `b's and then
+an infinite number of empty strings following the last `b',
+so the reported substring is one of the empties.)
+.PP
+If REG_STARTEND is specified,
+.I pmatch
+must point to at least one
+.I regmatch_t
+(even if
+.I nmatch
+is 0 or REG_NOSUB was specified),
+to hold the input offsets for REG_STARTEND.
+Use for output is still entirely controlled by
+.IR nmatch ;
+if
+.I nmatch
+is 0 or REG_NOSUB was specified,
+the value of
+.IR pmatch [0]
+will not be changed by a successful
+.IR regexec .
+.PP
+.I Regerror
+maps a non-zero
+.I errcode
+from either
+.I regcomp
+or
+.I regexec
+to a human-readable, printable message.
+If
+.I preg
+is non-NULL,
+the error code should have arisen from use of
+the
+.I regex_t
+pointed to by
+.IR preg ,
+and if the error code came from
+.IR regcomp ,
+it should have been the result from the most recent
+.I regcomp
+using that
+.IR regex_t .
+.RI ( Regerror
+may be able to supply a more detailed message using information
+from the
+.IR regex_t .)
+.I Regerror
+places the NUL-terminated message into the buffer pointed to by
+.IR errbuf ,
+limiting the length (including the NUL) to at most
+.I errbuf_size
+bytes.
+If the whole message won't fit,
+as much of it as will fit before the terminating NUL is supplied.
+In any case,
+the returned value is the size of buffer needed to hold the whole
+message (including terminating NUL).
+If
+.I errbuf_size
+is 0,
+.I errbuf
+is ignored but the return value is still correct.
+.PP
+If the
+.I errcode
+given to
+.I regerror
+is first ORed with REG_ITOA,
+the ``message'' that results is the printable name of the error code,
+e.g. ``REG_NOMATCH'',
+rather than an explanation thereof.
+If
+.I errcode
+is REG_ATOI,
+then
+.I preg
+shall be non-NULL and the
+.I re_endp
+member of the structure it points to
+must point to the printable name of an error code;
+in this case, the result in
+.I errbuf
+is the decimal digits of
+the numeric value of the error code
+(0 if the name is not recognized).
+REG_ITOA and REG_ATOI are intended primarily as debugging facilities;
+they are extensions,
+compatible with but not specified by POSIX 1003.2,
+and should be used with
+caution in software intended to be portable to other systems.
+Be warned also that they are considered experimental and changes are possible.
+.PP
+.I Regfree
+frees any dynamically-allocated storage associated with the compiled RE
+pointed to by
+.IR preg .
+The remaining
+.I regex_t
+is no longer a valid compiled RE
+and the effect of supplying it to
+.I regexec
+or
+.I regerror
+is undefined.
+.PP
+None of these functions references global variables except for tables
+of constants;
+all are safe for use from multiple threads if the arguments are safe.
+.SH IMPLEMENTATION CHOICES
+There are a number of decisions that 1003.2 leaves up to the implementor,
+either by explicitly saying ``undefined'' or by virtue of them being
+forbidden by the RE grammar.
+This implementation treats them as follows.
+.PP
+See
+.ZR
+for a discussion of the definition of case-independent matching.
+.PP
+There is no particular limit on the length of REs,
+except insofar as memory is limited.
+Memory usage is approximately linear in RE size, and largely insensitive
+to RE complexity, except for bounded repetitions.
+See BUGS for one short RE using them
+that will run almost any system out of memory.
+.PP
+A backslashed character other than one specifically given a magic meaning
+by 1003.2 (such magic meanings occur only in obsolete [``basic''] REs)
+is taken as an ordinary character.
+.PP
+Any unmatched [ is a REG_EBRACK error.
+.PP
+Equivalence classes cannot begin or end bracket-expression ranges.
+The endpoint of one range cannot begin another.
+.PP
+RE_DUP_MAX, the limit on repetition counts in bounded repetitions, is 255.
+.PP
+A repetition operator (?, *, +, or bounds) cannot follow another
+repetition operator.
+A repetition operator cannot begin an expression or subexpression
+or follow `^' or `|'.
+.PP
+`|' cannot appear first or last in a (sub)expression or after another `|',
+i.e. an operand of `|' cannot be an empty subexpression.
+An empty parenthesized subexpression, `()', is legal and matches an
+empty (sub)string.
+An empty string is not a legal RE.
+.PP
+A `{' followed by a digit is considered the beginning of bounds for a
+bounded repetition, which must then follow the syntax for bounds.
+A `{' \fInot\fR followed by a digit is considered an ordinary character.
+.PP
+`^' and `$' beginning and ending subexpressions in obsolete (``basic'')
+REs are anchors, not ordinary characters.
+.SH SEE ALSO
+grep(1), re_format(7)
+.PP
+POSIX 1003.2, sections 2.8 (Regular Expression Notation)
+and
+B.5 (C Binding for Regular Expression Matching).
+.SH DIAGNOSTICS

+.I regcomp
+and

+.SH HISTORY
+Originally written by Henry Spencer.
+Altered for inclusion in the 4.4BSD distribution.
+.SH BUGS
+This is an alpha release with known defects.
+Please report problems.
+.PP
+There is one known functionality bug.
+The implementation of internationalization is incomplete:
+the locale is always assumed to be the default one of 1003.2,
+and only the collating elements etc. of that locale are available.
+.PP
+The back-reference code is subtle and doubts linger about its correctness
+in complex cases.
+.PP
+.I Regexec
+performance is poor.
+This will improve with later releases.
+.I Nmatch
+exceeding 0 is expensive;
+.I nmatch
+exceeding 1 is worse.
+.I Regexec
+is largely insensitive to RE complexity \fIexcept\fR that back
+references are massively expensive.
+RE length does matter; in particular, there is a strong speed bonus
+for keeping RE length under about 30 characters,
+with most special characters counting roughly double.
+.PP
+.I Regcomp
+implements bounded repetitions by macro expansion,
+which is costly in time and space if counts are large
+or bounded repetitions are nested.
+An RE like, say,
+`((((a{1,100}){1,100}){1,100}){1,100}){1,100}'
+will (eventually) run almost any existing machine out of swap space.
+.PP
+There are suspected problems with response to obscure error conditions.
+Notably,
+certain kinds of internal overflow,
+produced only by truly enormous REs or by multiply nested bounded repetitions,
+are probably not handled well.
+.PP
+Due to a mistake in 1003.2, things like `a)b' are legal REs because `)' is
+a special character only in the presence of a previous unmatched `('.
+This can't be fixed until the spec is fixed.
+.PP
+The standard's definition of back references is vague.
+For example, does
+`a\e(\e(b\e)*\e2\e)*d' match `abbbd'?
+Until the standard is clarified,
+behavior in such cases should not be relied on.
+.PP
+The implementation of word-boundary matching is a bit of a kludge,
+and bugs may lurk in combinations of word-boundary matching and anchoring.

+RPCSRC 4.0 7/11/89
+
+This distribution contains Sun Microsystem's implementation of the
+RPC and XDR protocols and is compatible with 4.2BSD and 4.3BSD.  Also
+included is complete documentation, utilities, RPC service
+specification files, and demonstration services in the format used by
+the RPC protocol compiler (rpcgen).  See WHAT'S NEW below for
+details.
+
+NOTE ABOUT SECURE RPC:
+
+This release of RPCSRC contains most of the code needed to implement
+Secure RPC (see "DES Authentication" in the RPC Protocol Specification,
+doc/rpc.rfc.ms).  Due to legal considerations, we are unable to
+distribute an implementation of DES, the Data Encryption Standard, which
+Secure RPC requires.  For this reason, all of the files, documentation, and
+programs associated with Secure RPC have been placed into a separate
+directory, secure_rpc.  The RPC library contained in the main body of this
+release *DOES NOT* support Secure RPC.  See secure_rpc/README for more
+details.  (A DES library was posted in Volume 18 of comp.sources.unix.)
+
+If you wish to report bugs found in this release, send mail to:
+
+Portable ONC/NFS
+Sun Microsystems, Inc
+MS 12-33
+2550 Garcia Avenue
+Mountain View, CA  94043
+
+or send Email to nfsnet@sun.com (the Internet) or sun!nfsnet (Usenet).
+
+ROADMAP
+
+The directory hierarchy is as follows:
+
+    demo/       Various demonstration services
+    demo/dir        Remote directory lister
+    demo/msg        Remote console message delivery service
+    demo/sort       Remote sort service
+
+    doc/        Documentation for RPC, XDR and NFS in "-ms" format.
+
+    etc/        Utilities (rpcinfo and portmap).  portmap must be
+                started by root before any other RPC network services are
+                used.  SEE BELOW FOR BUGFIX TO 4.3BSD COMPILER.
+
+    man/        Manual pages for RPC library, rpcgen, and utilities.
+
+    rpc/        The RPC and XDR library.  SEE BELOW
+                FOR BUGFIX TO 4.2BSD COMPILER.
+
+    rpcgen/     The RPC Language compiler (for .x files)
+
+    rpcsvc/     Service definition files for various services and the
+                server and client code for the Remote Status service.
+
+    secure_rpc/ The files in this directory are used to build a version of
+                the RPC library with DES Authentication.  See the README
+                file in that directory for more details.
+
+BUILD INSTRUCTIONS
+
+Makefiles can be found in all directories except for man.  The
+Makefile in the top directory will cause these others to be invoked
+(except for in the doc, man and demo directories), in turn building the
+entire release.
+
+WARNING!  THE DEFAULT INSTALLATION PROCEDURES WILL INSTALL FILES
+IN /usr/include, /usr/lib, /usr/bin and /etc.
+
+The master RPC include file, rpc/rpc.h, is used by all programs and
+routines that use RPC.  It includes other RPC and system include files
+needed by the RPC system.  PLEASE NOTE: If your system has NFS, it
+may have been based on Sun's NFS Source.  The include files installed
+by this package may duplicate include files you will find on your NFS
+system.  The RPCSRC 4.0 include files are upwardly compatible to all
+NFS Source include files as of the date of this distribution (not
+including any new definitions or declarations added by your system
+vendor).  HOWEVER: Please read the comments towards the end of
+rpc/rpc.h regarding rpc/netdb.h.  You may need to uncomment the
+inclusion of that file if the structures it defines are already
+defined by your system's include files.
+
+After making any compiler fixes that are needed (see below), at
+the top directory, type:
+
+    make install
+
+For all installations, the Makefile macro DESTDIR is prepended to the
+installation path.  It is defined to be null in the Makefiles, so
+installations are relative to root.  (You will probably need root
+privileges for installing the files under the default path.)  To
+install the files under some other tree (e.g., /usr/local), use the
+command:
+
+    make install DESTDIR=/usr/local
+
+This will place the include files in /usr/local/usr/include, the RPC
+library in /usr/local/usr/lib, rpcgen in /usr/local/usr/bin, and the
+utilities in /usr/local/etc.  You'll have to edit the Makefiles or
+install the files by hand if you want to do anything other than this
+kind of relocation of the installation tree.
+
+The RPC library will be built and installed first.  By default it is
+installed in /usr/lib as "librpclib.a".  The directory
+/usr/include/rpc will also be created, and several header files will
+be installed there.  ALL RPC SERVICES INCLUDE THESE HEADER FILES.
+
+The programs in etc/ link in routines from librpclib.a.  If you change
+where it is installed, be sure to edit etc/'s Makefile to reflect this.
+These programs are installed in /etc.  PORTMAP MUST BE RUNNING ON
+YOUR SYSTEM BEFORE YOU START ANY OTHER RPC SERVICE.
+
+rpcgen is installed in /usr/bin.  This program is required to build
+the demonstration services in demo and the rstat client and server in
+rpcsvc/.
+
+The rpcsvc/ directory will install its files in the directory
+/usr/include/rpcsvc.  The Remote Status service (rstat_svc) will be
+compiled and installed in /etc.  If you wish to make this service
+available, you should either start this service when needed or have
+it started at boot time by invoking it in your /etc/rc.local script.
+(Be sure that portmap is started first!)  Sun has modified its
+version of inetd to automatically start RPC services.  (Use "make
+LIB=" when building rstat on a Sun Workstation.)  The Remote Status
+client (rstat) will be installed in /usr/bin.  This program queries
+the rstat_svc on a remote host and prints a system status summary
+similar to the one printed by "uptime".
+
+The documentation is not built during the "make install" command.
+Typing "make" in the doc directory will cause all of the manuals to
+be formatted using nroff into a single file.  We have had a report
+that certain "troff" equivalents have trouble processing the full
+manual.  If you have trouble, try building the manuals individually
+(see the Makefile).
+
+The demonstration services in the demo directory are not built by the
+top-level "make install" command.  To build these, cd to the demo
+directory and enter "make".  The three services will be built.
+RPCGEN MUST BE INSTALLED in a path that make can find.  To run the
+services, start the portmap program as root and invoke the service
+(you probably will want to put it in the background).  rpcinfo can be
+used to check that the service succeeded in getting registered with
+portmap, and to ping the service (see rpcinfo's man page).  You can
+then use the corresponding client program to exercise the service.
+To build these services on a Sun workstation, you must prevent the
+Makefile from trying to link the RPC library (as these routines are
+already a part of Sun's libc).  Use: "make LIB=".
+
+BUGFIX FOR 4.3BSD COMPILER
+
+The use of a 'void *' declaration for one of the arguments in
+the reply_proc() procedure in etc/rpcinfo.c will trigger a bug
+in the 4.3BSD compiler.  The bug is fixed by the following change to
+the compiler file mip/manifest.h:
+
+*** manifest.h.r1.1	Thu Apr 30 13:52:25 1987
+--- manifest.h.r1.2	Mon Nov 23 18:58:17 1987
+***************
+*** 21,27 ****
+  /*
+   * Bogus type values
+   */

+  #define TVOID	FTN		/* function returning UNDEF (for void) */
+  
+  /*

+   */
+! #define TNULL	INCREF(MOETY)	/* pointer to MOETY -- impossible type */
+  #define TVOID	FTN		/* function returning UNDEF (for void) */
+  
+  /*
+
+If you cannot fix your compiler, change the declaration in reply_proc()
+from 'void *' to 'char *'.
+
+BUGFIX FOR 4.2BSD COMPILER
+
+Unpatched 4.2BSD compilers complain about valid C.  You can make old
+compilers happy by changing some voids to ints.  However, the fix to
+the 4.2 VAX compiler is as follows (to mip/trees.c):
+

+
+WHAT'S NEW IN THIS RELEASE: RPCSRC 4.0
+
+The previous release was RPCSRC 3.9.  As with all previous releases,
+this release is based directly on files from Sun Microsystem's
+implementation.
+
+Upgrade from RPCSRC 3.9
+
+1)  RPCSRC 4.0 upgrades RPCSRC 3.9.  Improvements from SunOS 4.0 have
+    been integrated into this release.
+
+Secure RPC (in the secure_rpc/ directory)
+
+2)  DES Authentication routines and programs are provided.
+3)  A new manual, "Secure NFS" is provided, which describes Secure RPC
+    and Secure NFS.
+4)  Skeleton routines and manual pages are provided which describe the
+    DES encryption procedures required by Secure RPC.  HOWEVER, NO DES
+    ROUTINE IS PROVIDED.
+
+New Functionality
+
+5)  rpcinfo can now be used to de-register services from the portmapper
+    which may have terminated abnormally.
+6)  A new client, rstat, is provided which queries the rstat_svc and
+    prints a status line similar to the one displayed by "uptime".

+.Nm getrpcport
+.Nd get RPC port number
+.Sh SYNOPSIS
+.Ft int
+.Fn getrpcport "char *host" "int prognum" "int versnum" "int proto"
+.Sh DESCRIPTION
+.Fn getrpcport
+returns the port number for version
+.Fa versnum
+of the RPC program
+.Fa prognum
+running on
+.Fa host
+and using protocol
+.Fa proto .
+It returns 0 if it cannot contact the portmapper, or if
+.Fa prognum
+is not registered.  If
+.Fa prognum
+is registered but not with version
+.Fa versnum ,
+it will still return a port number (for some version of the program)
+indicating that the program is indeed registered.
+The version mismatch will be detected upon the first call to the service.

+.SH NAME
+rpc \- library routines for remote procedure calls
+.SH SYNOPSIS AND DESCRIPTION
+These routines allow C programs to make procedure
+calls on other machines across the network.
+First, the client calls a procedure to send a
+data packet to the server.
+Upon receipt of the packet, the server calls a dispatch routine
+to perform the requested service, and then sends back a
+reply.
+Finally, the procedure call returns to the client.
+.LP
+Routines that are used for Secure RPC (DES authentication) are described in
+.BR rpc_secure (3N).
+Secure RPC can be used only if DES encryption is available.

+Call the remote procedure associated with

+.I procnum
+on the machine,
+.IR host .
+The parameter
+.I in
+is the address of the procedure's argument(s), and
+.I out
+is the address of where to place the result(s);
+.I inproc
+is used to encode the procedure's parameters, and
+.I outproc
+is used to decode the procedure's results.
+This routine returns zero if it succeeds, or the value of
+.B "enum clnt_stat"
+cast to an integer if it fails.
+The routine
+.B clnt_perrno(\|)
+is handy for translating failure statuses into messages.

+Warning: calling remote procedures with this routine

+.SH NAME
+xdr \- library routines for external data representation
+.SH SYNOPSIS AND DESCRIPTION
+.LP
+These routines allow C programmers to describe
+arbitrary data structures in a machine-independent fashion.
+Data for remote procedure calls are transmitted using these
+routines.
+.LP
+.ft B

+xdr_array(xdrs, arrp, sizep, maxsize, elsize, elproc)
+\s-1XDR\s0 *xdrs;
+char **arrp;
+u_int *sizep, maxsize, elsize;
+xdrproc_t elproc;
+.fi
+.ft R
+.IP
+A filter primitive that translates between variable-length
+arrays
+and their corresponding external representations. The
+parameter
+.I arrp
+is the address of the pointer to the array, while
+.I sizep
+is the address of the element count of the array;
+this element count cannot exceed
+.IR maxsize .
+The parameter
+.I elsize
+is the
+.I sizeof
+each of the array's elements, and
+.I elproc
+is an
+.SM XDR
+filter that translates between
+the array elements' C form, and their external
+representation.
+This routine returns one if it succeeds, zero otherwise.

+.ft B
+.nf
+.sp .5
+xdr_bool(xdrs, bp)
+\s-1XDR\s0 *xdrs;
+bool_t *bp;
+.fi
+.ft R
+.IP
+A filter primitive that translates between booleans (C
+integers)
+and their external representations. When encoding data, this
+filter produces values of either one or zero.
+This routine returns one if it succeeds, zero otherwise.
+.br
+.if t .ne 10

+\s-1XDR\s0 *xdrs;
+char **sp;
+u_int *sizep, maxsize;
+.fi
+.ft R
+.IP
+A filter primitive that translates between counted byte
+strings and their external representations.
+The parameter
+.I sp
+is the address of the string pointer. The length of the
+string is located at address
+.IR sizep ;
+strings cannot be longer than
+.IR maxsize .
+This routine returns one if it succeeds, zero otherwise.

+.ft B
+.nf
+.sp .5
+xdr_char(xdrs, cp)
+\s-1XDR\s0 *xdrs;
+char *cp;
+.fi
+.ft R
+.IP
+A filter primitive that translates between C characters
+and their external representations.
+This routine returns one if it succeeds, zero otherwise.
+Note: encoded characters are not packed, and occupy 4 bytes
+each. For arrays of characters, it is worthwhile to
+consider
+.BR xdr_bytes(\|) ,
+.B xdr_opaque(\|)
+or
+.BR xdr_string(\|) .

+void
+xdr_destroy(xdrs)
+\s-1XDR\s0 *xdrs;
+.fi
+.ft R
+.IP
+A macro that invokes the destroy routine associated with the
+.SM XDR
+stream,
+.IR xdrs .
+Destruction usually involves freeing private data structures
+associated with the stream.  Using
+.I xdrs
+after invoking
+.B xdr_destroy(\|)
+is undefined.

+void
+xdr_free(proc, objp)
+xdrproc_t proc;

+.fi
+.ft R
+.IP
+Generic freeing routine. The first argument is the
+.SM XDR
+routine for the object being freed. The second argument
+is a pointer to the object itself. Note: the pointer passed
+to this routine is
+.I not
+freed, but what it points to
+.I is
+freed (recursively).

+u_int
+xdr_getpos(xdrs)
+\s-1XDR\s0 *xdrs;
+.fi
+.ft R
+.IP
+A macro that invokes the get-position routine
+associated with the
+.SM XDR
+stream,
+.IR xdrs .
+The routine returns an unsigned integer,
+which indicates the position of the
+.SM XDR
+byte stream.
+A desirable feature of
+.SM XDR
+streams is that simple arithmetic works with this number,
+although the
+.SM XDR
+stream instances need not guarantee this.

+.fi
+.ft R
+.IP
+A macro that invokes the in-line routine associated with the
+.SM XDR
+stream,
+.IR xdrs .
+The routine returns a pointer
+to a contiguous piece of the stream's buffer;
+.I len
+is the byte length of the desired buffer.
+Note: pointer is cast to
+.BR "long *" .
+.IP
+Warning:
+.B xdr_inline(\|)
+may return
+.SM NULL
+(0)
+if it cannot allocate a contiguous piece of a buffer.
+Therefore the behavior may vary among stream instances;
+it exists for the sake of efficiency.

+.fi
+.ft R
+.IP
+This routine initializes the

+stream object pointed to by

+The stream's data is written to a buffer of size
+.IR sendsize ;
+a value of zero indicates the system should use a suitable
+default. The stream's data is read from a buffer of size
+.IR recvsize ;
+it too can be set to a suitable default by passing a zero
+value.
+When a stream's output buffer is full,
+.I writeit
+is called.  Similarly, when a stream's input buffer is empty,
+.I readit
+is called.  The behavior of these two routines is similar to
+the
+system calls
+.B read
+and
+.BR write ,
+except that
+.I handle
+is passed to the former routines as the first parameter.
+Note: the

+.Sh NAME
+.Nm fgetln
+.Nd get a line from a stream
+.Sh SYNOPSIS
+.Fd #include <stdio.h>
+.Ft char *
+.Fn fgetln "FILE *stream" "size_t *len"
+.Sh DESCRIPTION
+The
+.Fn fgetln
+function
+returns a pointer to the next line from the stream referenced by
+.Fa stream .
+This line is
+.Em not
+a C string as it does not end with a terminating
+.Dv NUL
+character.
+The length of the line, including the final newline,
+is stored in the memory location to which
+.Fa len
+points.
+(Note, however, that if the line is the last
+in a file that does not end in a newline,
+the returned text will not contain a newline.)
+.Sh RETURN VALUES
+Upon successful completion a pointer is returned;
+this pointer becomes invalid after the next
+.Tn I/O
+operation on
+.Fa stream
+(whether successful or not)
+or as soon as the stream is closed.
+Otherwise,
+.Dv NULL
+is returned.
+The
+.Fn fgetln
+function
+does not distinguish between end-of-file and error; the routines
+.Xr feof 3
+and
+.Xr ferror 3
+must be used
+to determine which occurred.
+If an error occurs, the global variable
+.Va errno
+is set to indicate the error.
+The end-of-file condition is remembered, even on a terminal, and all
+subsequent attempts to read will return
+.Dv NULL
+until the condition is
+cleared with
+.Xr clearerr 3 .
+.Pp
+The text to which the returned pointer points may be modified,
+provided that no changes are made beyond the returned size.
+These changes are lost as soon as the pointer becomes invalid.
+.Sh ERRORS
+.Bl -tag -width [EBADF]
+.It Bq Er EBADF
+The argument
+.Fa stream
+is not a stream open for reading.
+.El
+.Pp
+The
+.Fn fgetln
+function
+may also fail and set
+.Va errno
+for any of the errors specified for the routines
+.Xr fflush 3 ,
+.Xr malloc 3 ,
+.Xr read 2 ,
+.Xr stat 2 ,
+or
+.Xr realloc 3 .
+.Sh SEE ALSO
+.Xr ferror 3 ,
+.Xr fgets 3 ,
+.Xr fopen 3 ,
+.Xr putc 3
+.Sh HISTORY
+The
+.Fn fgetln
+function first appeared in 4.4BSD.

+.Fn fgets "char *str" "size_t size" "FILE *stream"
+.Ft char *
+.Fn gets "char *str"
+.Sh DESCRIPTION
+The
+.Fn fgets
+function
+reads at most one less than the number of characters specified by
+.Xr size
+from the given
+.Fa stream
+and stores them in the string
+.Fa str .
+Reading stops when a newline character is found,
+at end-of-file or error.
+The newline, if any, is retained.
+In any case a
+.Ql \e0
+character is appended to end the string.
+.Pp
+The
+.Fn gets
+function
+is equivalent to
+.Fn fgets
+with an infinite
+.Xr size
+and a
+.Fa stream
+of
+.Em stdin ,
+except that the newline character (if any) is not stored in the string.
+It is the caller's responsibility to ensure that the input line,
+if any, is sufficiently short to fit in the string.
+.Sh RETURN VALUES
+.Pp
+Upon successful completion,
+.Fn fgets
+and 
+.Fn gets
+return
+a pointer to the string.
+If end-of-file or an error occurs before any characters are read, 
+they return
+.Dv NULL.
+The
+.Fn fgets
+and
+functions
+.Fn gets
+do not distinguish between end-of-file and error, and callers must use
+.Xr feof 3
+and
+.Xr ferror 3
+to determine which occurred.
+.Sh ERRORS
+.Bl -tag -width Er
+.It Bq Er EBADF
+The given
+.Fa stream
+is not a readable stream.

+.Pp
+The function
+.Fn fgets
+may also fail and set

+.Xr fgetln 3
+.Sh STANDARDS
+The functions
+.Fn fgets
+and
+.Fn gets
+conform to
+.St -ansiC .
+.Sh BUGS
+Since it is usually impossible to ensure that the next input line
+is less than some arbitrary length, and because overflowing the
+input buffer is almost invariably a security violation, programs
+should
+.Em NEVER
+use
+.Fn gets .
+The
+.Fn gets
+function
+exists purely to conform to
+.St -ansiC .

+.Sh NAME
+.Nm fopen ,
+.Nm fdopen ,
+.Nm freopen
+.Nd stream open functions
+.Sh SYNOPSIS
+.Fd #include <stdio.h>
+.Ft FILE *
+.Fn fopen "char *path" "char *mode"
+.Ft FILE *
+.Fn fdopen "int fildes" "char *mode"
+.Ft FILE *
+.Fn freopen "char *path" "char *mode" "FILE *stream"
+.Sh DESCRIPTION
+The
+.Fn fopen
+function
+opens the file whose name is the string pointed to by
+.Fa path
+and associates a stream with it.
+.Pp
+The argument
+.Fa mode
+points to a string beginning with one of the following
+sequences (Additional characters may follow these sequences.):
+.Bl -tag -width indent
+.It Dq Li r
+Open text file for reading.
+The stream is positioned at the beginning of the file.
+.It Dq Li r+
+Open for reading and writing.
+The stream is positioned at the beginning of the file.
+.It Dq Li w
+Truncate file to zero length or create text file for writing.
+The stream is positioned at the beginning of the file.
+.No It Dq Li w+
+Open for reading and writing.
+The file is created if it does not exist, otherwise it is truncated.
+The stream is positioned at the beginning of the file.
+.It Dq Li a
+Open for writing.
+The file is created if it does not exist.
+The stream is positioned at the end of the file.
+.It Dq Li a+
+Open for reading and writing.
+The file is created if it does not exist.
+The stream is positioned at the end of the file.
+.El
+.Pp
+The
+.Fa mode
+string can also include the letter ``b'' either as a third character or
+as a character between the characters in any of the two-character strings
+described above.
+This is strictly for compatibility with
+.St -ansiC
+and has no effect; the ``b'' is ignored.
+.Pp
+Any created files will have mode
+.Pf \\*q Dv S_IRUSR
+\&|
+.Dv S_IWUSR
+\&|
+.Dv S_IRGRP
+\&|
+.Dv S_IWGRP
+\&|
+.Dv S_IROTH
+\&|
+.Dv S_IWOTH Ns \\*q
+.Pq Li 0666 ,
+as modified by the process'
+umask value (see
+.Xr umask 2 ) .
+.Pp
+Reads and writes may be intermixed on read/write streams in any order,
+and do not require an intermediate seek as in previous versions of
+.Em stdio .
+This is not portable to other systems, however;
+.Tn ANSI C
+requires that
+a file positioning function intervene between output and input, unless
+an input operation encounters end-of-file.
+.Pp
+The
+.Fn fdopen
+function associates a stream with the existing file descriptor,
+.Fa fildes .
+The
+.Fa mode
+of the stream must be compatible with the mode of the file descriptor.
+.Pp
+The
+.Fn freopen
+function
+opens the file whose name is the string pointed to by
+.Fa path
+and associates the stream pointed to by
+.Fa stream
+with it.
+The original stream (if it exists) is closed.
+The
+.Fa mode
+argument is used just as in the
+.Xr fopen
+function.
+The primary use of the
+.Fn freopen
+function
+is to change the file associated with a
+standard text stream
+.Pf ( Em stderr ,
+.Em stdin ,
+or
+.Em stdout ) .
+.Sh RETURN VALUES
+Upon successful completion
+.Fn fopen ,
+.Fn fdopen
+and
+.Fn freopen
+return a
+.Tn FILE
+pointer.
+Otherwise,
+.Dv NULL
+is returned and the global variable
+.Va errno
+is set to indicate the error.
+.Sh ERRORS
+.Bl -tag -width Er
+.It Bq Er EINVAL
+The
+.Fa mode
+provided to
+.Fn fopen ,
+.Fn fdopen ,
+or
+.Fn freopen
+was invalid.
+.El
+.Pp
+The
+.Fn fopen ,
+.Fn fdopen
+and
+.Fn freopen
+functions
+may also fail and set
+.Va errno
+for any of the errors specified for the routine
+.Xr malloc 3 .
+.Pp
+The
+.Fn fopen
+function
+may also fail and set
+.Va errno
+for any of the errors specified for the routine
+.Xr open 2 .
+.Pp
+The
+.Fn fdopen
+function
+may also fail and set
+.Va errno
+for any of the errors specified for the routine
+.Xr fcntl 2 .
+.Pp
+The
+.Fn freopen
+function
+may also fail and set
+.Va errno
+for any of the errors specified for the routines
+.Xr open 2 ,
+.Xr fclose 3
+and
+.Xr fflush 3 .
+.Sh SEE ALSO
+.Xr open 2 ,
+.Xr fclose 3 ,
+.Xr fseek 3 ,
+.Xr funopen 3
+.Sh STANDARDS
+The
+.Fn fopen
+and
+.Fn freopen
+functions
+conform to
+.St -ansiC .
+The
+.Fn fdopen
+function
+conforms to
+.St -p1003.1-88 .

+.Sh NAME
+.Nm fgetpos ,
+.Nm fseek ,
+.Nm fsetpos ,
+.Nm ftell ,
+.Nm rewind
+.Nd reposition a stream
+.Sh SYNOPSIS
+.Fd #include <stdio.h>
+.Ft int
+.Fn fseek "FILE *stream" "long offset" "int whence"
+.Ft long
+.Fn ftell "FILE *stream"
+.Ft void
+.Fn rewind "FILE *stream"
+.Ft int
+.Fn fgetpos "FILE *stream" "fpos_t *pos"
+.Ft int
+.Fn fsetpos "FILE *stream" "fpos_t *pos"
+.Sh DESCRIPTION
+The
+.Fn fseek
+function sets the file position indicator for the stream pointed
+to by
+.Fa stream .
+The new position, measured in bytes, is obtained by adding
+.Fa offset
+bytes to the position specified by
+.Fa whence .
+If 
+.Fa whence
+is set to
+.Dv SEEK_SET ,
+.Dv SEEK_CUR ,
+or
+.Dv SEEK_END ,
+the offset is relative to the
+start of the file, the current position indicator, or end-of-file,
+respectively.
+A successful call to the
+.Fn fseek
+function clears the end-of-file indicator for the stream and undoes
+any effects of the
+.Xr ungetc 3
+function on the same stream.
+.Pp
+The
+.Fn ftell
+function
+obtains the current value of the file position indicator for the
+stream pointed to by
+.Fa stream .
+.Pp
+The
+.Fn rewind
+function sets the file position indicator for the stream pointed
+to by
+.Fa stream
+to the beginning of the file.
+It is equivalent to:
+.Pp
+.Dl (void)fseek(stream, 0L, SEEK_SET)
+.Pp
+except that the error indicator for the stream is also cleared
+(see
+.Xr clearerr 3 ) .
+.Pp
+The
+.Fn fgetpos
+and
+.Fn fsetpos
+functions
+are alternate interfaces equivalent to
+.Fn ftell
+and
+.Fn fseek
+(with whence set to
+.Dv SEEK_SET
+), setting and storing the current value of
+the file offset into or from the object referenced by 
+.Fa pos .
+On some
+.Pq non- Ns Tn UNIX
+systems an
+.Dq Fa fpos_t
+object may be a complex object
+and these routines may be the only way to portably reposition a text stream.
+.Sh RETURN VALUES
+The
+.Fn rewind
+function
+returns no value.
+Upon successful completion,
+.Fn fgetpos ,
+.Fn fseek ,
+.Fn fsetpos
+return 0,
+and
+.Fn ftell
+returns the current offset.
+Otherwise, 
+.Fn fseek
+returns \-1 and 
+the others
+return a nonzero value and the global variable 
+.Va errno
+is set to indicate the error.
+.Sh ERRORS
+.Bl -tag -width Er
+.It Bq Er EBADF
+The
+.Fa stream
+specified
+is not a seekable stream.
+.It Bq Er EINVAL
+The
+.Fa whence
+argument to 
+.Fn fseek
+was not
+.Dv SEEK_SET ,
+.Dv SEEK_END ,
+or
+.Dv SEEK_CUR .
+.El
+.Pp
+The function
+.Fn fgetpos ,
+.Fn fseek ,
+.Fn fsetpos ,
+and 
+.Fn ftell
+may also fail and set
+.Va errno
+for any of the errors specified for the routines
+.Xr fflush 3 ,
+.Xr fstat 2 ,
+.Xr lseek 2 ,
+and 
+.Xr malloc 3 .
+.Sh SEE ALSO
+.Xr lseek 2
+.Sh STANDARDS
+The
+.Fn fgetpos ,
+.Fn fsetpos ,
+.Fn fseek ,
+.Fn ftell ,
+and
+.Fn rewind
+functions
+conform to
+.St -ansiC .

+.Dt FUNOPEN 3
+.Os
+.Sh NAME
+.Nm funopen ,
+.Nm fropen ,
+.Nm fwopen
+.Nd open a stream
+.Sh SYNOPSIS
+.Fd #include <stdio.h>
+.Ft FILE *
+.Fn funopen "void  *cookie" "int  (*readfn)(void *, char *, int)" "int (writefn*)(void *, const char *, int)" "fpos_t (seekfn*)(void *, fpos_t, int)" "int (closefn*)(void *)"
+.Ft FILE *
+.Fn fropen "void  *cookie" "int  (*readfn)(void *, char *, int)"
+.Ft FILE *
+.Fn fwopen "void  *cookie" "int  (*writefn)(void *, char *, int)"
+.Sh DESCRIPTION
+The
+.Fn funopen
+function
+associates a stream with up to four
+.Dq Tn I/O No functions .
+Either 
+.Fa readfn
+or
+.Fa writefn
+must be specified;
+the others can be given as an appropriately-typed
+.Dv NULL
+pointer.
+These
+.Tn I/O
+functions will be used to read, write, seek and
+close the new stream.
+.Pp
+In general, omitting a function means that any attempt to perform the
+associated operation on the resulting stream will fail.
+If the close function is omitted, closing the stream will flush 
+any buffered output and then succeed.
+.Pp
+The calling conventions of
+.Fa readfn ,
+.Fa writefn ,
+.Fa seekfn
+and
+.Fa closefn
+must match those, respectively, of
+.Xr read 2 ,
+.Xr write 2 ,
+.Xr seek 2 ,
+and
+.Xr close 2
+with the single exception that they are passed the
+.Fa cookie
+argument specified to 
+.Fn funopen
+in place of the traditional file descriptor argument.
+.Pp
+Read and write
+.Tn I/O
+functions are allowed to change the underlying buffer
+on fully buffered or line buffered streams by calling
+.Xr setvbuf 3 .
+They are also not required to completely fill or empty the buffer.
+They are not, however, allowed to change streams from unbuffered to buffered
+or to change the state of the line buffering flag.
+They must also be prepared to have read or write calls occur on buffers other
+than the one most recently specified.
+.Pp
+All user
+.Tn I/O
+functions can report an error by returning \-1.
+Additionally, all of the functions should set the external variable
+.Va errno
+appropriately if an error occurs.
+.Pp
+An error on 
+.Fn closefn
+does not keep the stream open.
+.Pp
+As a convenience, the include file
+.Aq Pa stdio.h
+defines the macros
+.Fn fropen
+and
+.Fn fwopen
+as calls to
+.Fn funopen
+with only a read or write function specified.
+.Sh RETURN VALUES
+Upon successful completion, 
+.Fn funopen
+returns a
+.Dv FILE
+pointer.
+Otherwise,
+.Dv NULL
+is returned and the global variable
+.Va errno
+is set to indicate the error.
+.Sh ERRORS
+.Bl -tag -width Er
+.It Bq Er EINVAL
+The
+.Fn funopen
+function
+was called without either a read or write function.
+The
+.Fn funopen
+function
+may also fail and set
+.Va errno
+for any of the errors
+specified for the routine
+.Xr malloc 3 .
+.El
+.Sh SEE ALSO
+.Xr fcntl 2 ,
+.Xr open 2 ,
+.Xr fclose 3 ,
+.Xr fopen 3 ,
+.Xr fseek 3 ,
+.Xr setbuf 3
+.Sh HISTORY
+The
+.Fn funopen
+functions first appeared in 4.4BSD.
+.Sh BUGS
+The
+.Fn funopen
+function
+may not be portable to systems other than
+.Bx .

+.Dt GETC 3
+.Os
+.Sh NAME
+.Nm fgetc ,
+.Nm getc ,
+.Nm getchar ,
+.Nm getw
+.Nd get next character or word from input stream
+.Sh SYNOPSIS
+.Fd #include <stdio.h>
+.Ft int
+.Fn fgetc "FILE *stream"
+.Ft int
+.Fn getc "FILE *stream"
+.Ft int
+.Fn getchar 
+.Ft int
+.Fn getw "FILE *stream"
+.Sh DESCRIPTION
+The
+.Fn fgetc
+function
+obtains the next input character (if present) from the stream pointed at by
+.Fa stream ,
+or the next character pushed back on the stream via
+.Xr ungetc .
+.Pp
+The
+.Fn getc
+function
+acts essentially identically to
+.Fn fgetc ,
+but is a macro that expands in-line.
+.Pp
+The
+.Fn getchar
+function
+is equivalent to:
+getc with the argument stdin.
+.Pp
+The
+.Fn getw
+function
+obtains the next
+.Em int
+(if present)
+from the stream pointed at by
+.Fa stream .
+.Sh RETURN VALUES
+If successful, these routines return the next requested object
+from the
+.Fa stream .
+If the stream is at end-of-file or a read error occurs,
+the routines return
+.Dv EOF .
+The routines
+.Xr feof 3
+and
+.Xr ferror 3
+must be used to distinguish between end-of-file and error.
+If an error occurs, the global variable
+.Va errno
+is set to indicate the error.
+The end-of-file condition is remembered, even on a terminal, and all
+subsequent attempts to read will return
+.Dv EOF
+until the condition is cleared with
+.Xr clearerr .
+.Sh SEE ALSO
+.Xr ferror 3 ,
+.Xr fread 3 ,
+.Xr fopen 3 ,
+.Xr putc 3 ,
+.Xr ungetc 3
+.Sh STANDARDS
+The
+.Fn fgetc ,
+.Fn getc
+and
+.Fn getchar
+functions
+conform to
+.St -ansiC .
+.Sh BUGS
+Since
+.Dv EOF
+is a valid integer value,
+.Xr feof
+and
+.Xr ferror
+must be used to check for failure after calling
+.Fn getw .
+The size and byte order of an
+.Em int
+varies from one machine to another, and
+.Fn getw
+is not recommended for portable applications.

+.Nd make temporary file name (unique)
+.Sh SYNOPSIS
+.Fd #include <unistd.h>
+.Ft char *
+.Fn mktemp "char *template"
+.Ft int
+.Fn mkstemp "char *template"
+.Sh DESCRIPTION
+The
+.Fn mktemp
+function
+takes the given file name template and overwrites a portion of it
+to create a file name.
+This file name is unique and suitable for use
+by the application.
+The template may be any file name with some number of
+.Ql X Ns s
+appended
+to it, for example
+.Pa /tmp/temp.XXXX .
+The trailing
+.Ql X Ns s
+are replaced with the current process number and/or a
+unique letter combination.
+The number of unique file names
+.Fn mktemp
+can return depends on the number of
+.Ql X Ns s
+provided; six
+.Ql X Ns s
+will
+result in
+.Fn mktemp
+testing roughly 26 ** 6 combinations.
+.Pp
+The
+.Fn mkstemp
+function
+makes the same replacement to the template and creates the template file,
+mode 0600, returning a file descriptor opened for reading and writing.
+This avoids the race between testing for a file's existence and opening it
+for use.
+.Sh RETURN VALUES
+The
+.Fn mktemp
+function
+returns a pointer to the template on success and
+.Dv NULL
+on failure.
+The
+.Fn mkstemp
+function
+returns \-1 if no suitable file could be created.
+If either call fails an error code is placed in the global variable
+.Va errno .
+.Sh ERRORS
+The
+.Fn mktemp
+and
+.Fn mkstemp
+functions
+may set
+.Va errno
+to one of the following values:
+.Bl -tag -width Er
+.It Bq Er ENOTDIR
+The pathname portion of the template is not an existing directory.
+.El
+.Pp
+The
+.Fn mktemp

+which are copied unchanged to the output stream;
+and conversion specifications, each of which results
+in fetching zero or more subsequent arguments.
+Each conversion specification is introduced by

+.Cm % .
+The arguments must correspond properly (after type promotion)
+with the conversion specifier.
+After the
+.Cm % ,
+the following appear in sequence:
+.Bl -bullet
+.It
+Zero or more of the following flags:
+.Bl -hyphen
+.It
+A
+.Cm #
+character
+specifying that the value should be converted to an ``alternate form''.
+For 
+.Cm c ,
+.Cm d ,
+.Cm i ,
+.Cm n ,
+.Cm p ,
+.Cm s ,
+and
+.Cm u ,
+conversions, this option has no effect.
+For 
+.Cm o
+conversions, the precision of the number is increased to force the first
+character of the output string to a zero (except if a zero value is printed
+with an explicit precision of zero).
+For
+.Cm x
+and
+.Cm X
+conversions, a non-zero result has the string
+.Ql 0x
+(or

+for
+.Cm X
+conversions) prepended to it.
+For
+.Cm e ,
+.Cm E ,
+.Cm f ,
+.Cm g ,
+and
+.Cm G ,
+conversions, the result will always contain a decimal point, even if no
+digits follow it (normally, a decimal point appears in the results of
+those conversions only if a digit follows).
+For
+.Cm g
+and
+.Cm G
+conversions, trailing zeros are not removed from the result as they
+would otherwise be.
+.It
+A zero
+.Sq Cm \&0
+character specifying zero padding.
+For all conversions except
+.Cm n ,
+the converted value is padded on the left with zeros rather than blanks.
+If a precision is given with a numeric conversion
+.Pf ( Mc d ,
+.Cm i ,
+.Cm o ,
+.Cm u ,
+.Cm i ,
+.Cm x ,
+and

+the
+.Sq Cm \&0

+.It
+A negative field width flag
+.Sq Cm \-
+indicates the converted value is to be left adjusted on the field boundary.
+Except for
+.Cm n
+conversions, the converted value is padded on the right with blanks,
+rather than on the left with blanks or zeros.
+A
+.Sq Cm \-
+overrides a
+.Sq Cm \&0
+if both are given.

+A space, specifying that a blank should be left before a positive number
+produced by a signed conversion
+.Pf ( Cm d ,
+.Cm e ,
+.Cm E ,
+.Cm f ,
+.Cm g ,
+.Cm G ,
+or
+.Cm i ) .
+.It
+A
+.Sq Cm +
+character specifying that a sign always be placed before a
+number produced by a signed conversion.
+A
+.Sq Cm +
+overrides a space if both are used.
+.El
+.It
+An optional decimal digit string specifying a minimum field width.
+If the converted value has fewer characters than the field width, it will
+be padded with spaces on the left (or right, if the left-adjustment
+flag has been given) to fill out
+the field width.
+.It
+An optional precision, in the form of a period
+.Sq Cm \&.
+followed by an
+optional digit string.  If the digit string is omitted, the precision
+is taken as zero.  This gives the minimum number of digits to appear for
+.Cm d ,
+.Cm i ,
+.Cm o ,
+.Cm u ,
+.Cm x ,
+and
+.Cm X
+conversions, the number of digits to appear after the decimal-point for
+.Cm e ,
+.Cm E ,
+and
+.Cm f
+conversions, the maximum number of significant digits for
+.Cm g
+and
+.Cm G
+conversions, or the maximum number of characters to be printed from a
+string for
+.Cm s
+conversions.
+.It
+The optional character
+.Cm h ,
+specifying that a following
+.Cm d ,
+.Cm i ,
+.Cm o ,
+.Cm u ,
+.Cm x ,
+or
+.Cm X
+conversion corresponds to a
+.Em short int
+or
+.Em unsigned short int
+argument, or that a following
+.Cm n
+conversion corresponds to a pointer to a
+.Em short int
+argument.
+.It
+The optional character
+.Cm l
+(ell) specifying that a following
+.Cm d ,
+.Cm i ,
+.Cm o ,
+.Cm u ,
+.Cm x ,
+or
+.Cm X
+conversion applies to a pointer to a
+.Em long int
+or
+.Em unsigned long int
+argument, or that a following
+.Cm n
+conversion corresponds to a pointer to a
+.Em long int
+argument.
+.It
+The optional character
+.Cm q ,
+specifying that a following
+.Cm d ,
+.Cm i ,
+.Cm o ,
+.Cm u ,
+.Cm x ,
+or
+.Cm X
+conversion corresponds to a
+.Em quad int
+or
+.Em unsigned quad int
+argument, or that a following
+.Cm n
+conversion corresponds to a pointer to a
+.Em quad int
+argument.
+.It
+The character
+.Cm L
+specifying that a following
+.Cm e ,
+.Cm E ,
+.Cm f ,
+.Cm g ,
+or
+.Cm G
+conversion corresponds to a
+.Em long double
+argument (but note that long double values are not currently supported
+by the
+.Tn VAX
+and
+.Tn Tahoe
+compilers).
+.It
+A character that specifies the type of conversion to be applied.
+.El
+.Pp
+A field width or precision, or both, may be indicated by
+an asterisk
+.Ql *
+instead of a
+digit string.
+In this case, an
+.Em int
+argument supplies the field width or precision.
+A negative field width is treated as a left adjustment flag followed by a
+positive field width; a negative precision is treated as though it were
+missing.
+.Pp
+The conversion specifiers and their meanings are:
+.Bl -tag -width "diouxX"
+.It Cm diouxX
+The
+.Em int
+(or appropriate variant) argument is converted to signed decimal
+.Pf ( Cm d
+and
+.Cm i ) ,
+unsigned octal
+.Pq Cm o ,
+unsigned decimal
+.Pq Cm u ,
+or unsigned hexadecimal
+.Pf ( Cm x
+and
+.Cm X )
+notation.  The letters
+.Cm abcdef
+are used for
+.Cm x
+conversions; the letters
+.Cm ABCDEF
+are used for
+.Cm X
+conversions.
+The precision, if any, gives the minimum number of digits that must
+appear; if the converted value requires fewer digits, it is padded on
+the left with zeros.
+.It Cm DOU
+The
+.Em long int
+argument is converted to signed decimal, unsigned octal, or unsigned
+decimal, as if the format had been
+.Cm ld ,
+.Cm lo ,
+or
+.Cm lu
+respectively.
+These conversion characters are deprecated, and will eventually disappear.
+.It Cm eE
+The
+.Em double
+argument is rounded and converted in the style
+.Sm off
+.Pf [\-]d Cm \&. No ddd Cm e No \\*(Pmdd
+.Sm on
+where there is one digit before the
+decimal-point character
+and the number of digits after it is equal to the precision;
+if the precision is missing,
+it is taken as 6; if the precision is
+zero, no decimal-point character appears.
+An
+.Cm E
+conversion uses the letter
+.Cm E
+(rather than
+.Cm e )
+to introduce the exponent.
+The exponent always contains at least two digits; if the value is zero,
+the exponent is 00.
+.It Cm f
+The
+.Em double
+argument is rounded and converted to decimal notation in the style
+.Sm off
+.Pf [-]ddd Cm \&. No ddd ,
+.Sm on
+where the number of digits after the decimal-point character
+is equal to the precision specification.
+If the precision is missing, it is taken as 6; if the precision is
+explicitly zero, no decimal-point character appears.
+If a decimal point appears, at least one digit appears before it.
+.It Cm g
+The
+.Em double
+argument is converted in style
+.Cm f
+or
+.Cm e
+(or
+.Cm E
+for
+.Cm G
+conversions).
+The precision specifies the number of significant digits.
+If the precision is missing, 6 digits are given; if the precision is zero,
+it is treated as 1.
+Style
+.Cm e
+is used if the exponent from its conversion is less than -4 or greater than
+or equal to the precision.
+Trailing zeros are removed from the fractional part of the result; a
+decimal point appears only if it is followed by at least one digit.
+.It Cm c
+The
+.Em int
+argument is converted to an
+.Em unsigned char ,
+and the resulting character is written.
+.It Cm s
+The
+.Dq Em char *
+argument is expected to be a pointer to an array of character type (pointer
+to a string).
+Characters from the array are written up to (but not including)
+a terminating
+.Dv NUL
+character;
+if a precision is specified, no more than the number specified are
+written.
+If a precision is given, no null character
+need be present; if the precision is not specified, or is greater than
+the size of the array, the array must contain a terminating
+.Dv NUL
+character.
+.It Cm p
+The
+.Dq Em void *
+pointer argument is printed in hexadecimal (as if by
+.Ql %#x
+or
+.Ql %#lx ) .
+.It Cm n
+The number of characters written so far is stored into the
+integer indicated by the
+.Dq Em int *
+(or variant) pointer argument.
+No argument is converted.
+.It Cm %
+A
+.Ql %
+is written. No argument is converted. The complete conversion specification
+is
+.Ql %% .
+.El
+.Pp
+In no case does a non-existent or small field width cause truncation of
+a field; if the result of a conversion is wider than the field width, the
+field is expanded to contain the conversion result.
+.Pp
+.Sh EXAMPLES
+.br
+To print a date and time in the form `Sunday, July 3, 10:02',
+where
+.Em weekday
+and
+.Em month
+are pointers to strings:

+#include <math.h>
+#include <stdio.h>
+fprintf(stdout, "pi = %.5f\en", 4 * atan(1.0));
+.Ed

+.Sh HISTORY
+The functions
+.Fn snprintf
+and
+.Fn vsnprintf
+are new to this release.
+.Sh BUGS
+The conversion formats
+.Cm \&%D ,
+.Cm \&%O ,
+and
+.Cm %U
+are not standard and
+are provided only for backward compatibility.
+The effect of padding the
+.Cm %p
+format with zeros (either by the
+.Sq Cm 0
+flag or by specifying a precision), and the benign effect (i.e., none)
+of the
+.Sq Cm #
+flag on
+.Cm %n
+and
+.Cm %p
+conversions, as well as other
+nonsensical combinations such as
+.Cm %Ld ,
+are not standard; such combinations
+should be avoided.
+.Pp
+Because
+.Fn sprintf
+and
+.Fn vsprintf
+assume an infinitely long string,
+callers must be careful not to overflow the actual space;
+this is often impossible to assure.
+For safety, programmers should use the
+.Fn snprintf
+interface instead.
+Unfortunately, this interface is not portable.

+.Fn putw "int w" "FILE *stream"
+.Sh DESCRIPTION
+The
+.Fn fputc
+function
+writes the character
+.Fa c
+(converted to an ``unsigned char'')
+to the output stream pointed to by
+.Fa stream .
+.Pp
+.Fn Putc
+acts essentially identically to
+.Fn fputc ,
+but is a macro that expands in-line. It may evaluate
+.Fa stream
+more than once, so arguments given to
+.Fn putc
+should not be expressions with potential side effects.
+.Pp
+.Fn Putchar
+is identical to
+.Fn putc
+with an output stream of
+.Em stdout .
+.Pp
+The
+.Fn putw
+function
+writes the specified
+.Em int
+to the named output
+.Fa stream .
+.Sh RETURN VALUES
+The functions,
+.Fn fputc ,
+.Fn putc
+and
+.Fn putchar
+return the character written.
+If an error occurs, the value
+.Dv EOF
+is returned.
+The
+.Fn putw
+function
+returns 0 on success;
+.Dv EOF
+is returned if
+a write error occurs,
+or if an attempt is made to write a read-only stream.
+.Sh SEE ALSO
+.Xr ferror 3 ,
+.Xr fopen 3 ,
+.Xr getc 3 ,

+.Sh STANDARDS
+The functions
+.Fn fputc ,
+.Fn putc ,

+A function
+.Fn putw
+function appeared in
+.At v6 .
+.Sh BUGS
+The size and byte order of an
+.Em int
+varies from one machine to another, and
+.Fn putw
+is not recommended for portable applications.

+.Sh DESCRIPTION
+The
+.Fn scanf
+family of functions scans input according to a
+.Fa format
+as described below.
+This format may contain
+.Em conversion specifiers ;
+the results from such conversions, if any,
+are stored through the
+.Em pointer
+arguments.
+The
+.Fn scanf
+function
+reads input from the standard input stream
+.Em stdin ,
+.Fn fscanf
+reads input from the stream pointer
+.Fa stream ,
+and
+.Fn sscanf
+reads its input from the character string pointed to by
+.Fa str .
+The
+.Fn vfscanf
+function
+is analogous to
+.Xr vfprintf 3
+and reads input from the stream pointer
+.Fa stream
+using a variable argument list of pointers (see
+.Xr stdarg 3 ) .
+The
+.Fn vscanf
+function scans a variable argument list from the standard input and
+the
+.Fn vsscanf
+function scans it from a string;
+these are analogous to
+the
+.Fn vprintf
+and
+.Fn vsprintf
+functions respectively.
+Each successive
+.Em pointer
+argument must correspond properly with
+each successive conversion specifier
+(but see `suppression' below).
+All conversions are introduced by the
+.Cm %
+(percent sign) character.
+The
+.Fa format
+string
+may also contain other characters.
+White space (such as blanks, tabs, or newlines) in the
+.Fa format
+string match any amount of white space, including none, in the input.
+Everything else
+matches only itself.
+Scanning stops
+when an input character does not match such a format character.
+Scanning also stops
+when an input conversion cannot be made (see below).
+.Sh CONVERSIONS
+Following the
+.Cm %
+character introducing a conversion
+there may be a number of
+.Em flag
+characters, as follows:
+.Bl -tag -width indent
+.It Cm *
+Suppresses assignment.
+The conversion that follows occurs as usual, but no pointer is used;
+the result of the conversion is simply discarded.
+.It Cm h
+Indicates that the conversion will be one of
+.Cm dioux
+or
+.Cm n
+and the next pointer is a pointer to a
+.Em short  int
+(rather than
+.Em int ) .
+.It Cm l
+Indicates either that the conversion will be one of
+.Cm dioux
+or
+.Cm n
+and the next pointer is a pointer to a
+.Em long  int
+(rather than
+.Em int ) ,
+or that the conversion will be one of
+.Cm efg
+and the next pointer is a pointer to
+.Em double
+(rather than
+.Em float ) .
+.It Cm q
+Indicates that the conversion will be one of
+.Cm dioux
+or
+.Cm n
+and the next pointer is a pointer to a
+.Em quad_t
+(rather than
+.Em int ) .
+.It Cm L
+Indicates that the conversion will be
+.Cm efg
+and the next pointer is a pointer to
+.Em long double .
+.El
+.Pp
+In addition to these flags,
+there may be an optional maximum field width,
+expressed as a decimal integer,
+between the
+.Cm %
+and the conversion.
+If no width is given,
+a default of `infinity' is used (with one exception, below);
+otherwise at most this many characters are scanned
+in processing the conversion.
+Before conversion begins,
+most conversions skip white space;
+this white space is not counted against the field width.
+.Pp
+The following conversions are available:
+.Bl -tag -width XXXX
+.It Cm %
+Matches a literal `%'.
+That is, `%\&%' in the format string
+matches a single input `%' character.
+No conversion is done, and assignment does not occur.
+.It Cm d
+Matches an optionally signed decimal integer;
+the next pointer must be a pointer to
+.Em int .
+.It Cm D
+Equivalent to
+.Cm ld ;
+this exists only for backwards compatibility.
+.It Cm i
+Matches an optionally signed integer;
+the next pointer must be a pointer to
+.Em int .
+The integer is read in base 16 if it begins
+with
+.Ql 0x
+or
+.Ql 0X ,
+in base 8 if it begins with
+.Ql 0 ,
+and in base 10 otherwise.
+Only characters that correspond to the base are used.
+.It Cm o
+Matches an octal integer;
+the next pointer must be a pointer to
+.Em unsigned int .
+.It Cm O
+Equivalent to
+.Cm lo ;
+this exists for backwards compatibility.
+.It Cm u
+Matches an optionally signed decimal integer;
+the next pointer must be a pointer to
+.Em unsigned int .
+.It Cm x
+Matches an optionally signed hexadecimal integer;
+the next pointer must be a pointer to
+.Em unsigned int .
+.It Cm X
+Equivalent to
+.Cm x .
+.It Cm f
+Matches an optionally signed floating-point number;
+the next pointer must be a pointer to
+.Em float .
+.It Cm e
+Equivalent to
+.Cm f .
+.It Cm g
+Equivalent to
+.Cm f .
+.It Cm E
+Equivalent to
+.Cm f .
+.It Cm G
+Equivalent to
+.Cm f .
+.It Cm s
+Matches a sequence of non-white-space characters;
+the next pointer must be a pointer to
+.Em char ,
+and the array must be large enough to accept all the sequence and the
+terminating
+.Dv NUL
+character.
+The input string stops at white space
+or at the maximum field width, whichever occurs first.
+.It Cm c
+Matches a sequence of
+.Em width
+count
+characters (default 1);
+the next pointer must be a pointer to
+.Em char ,
+and there must be enough room for all the characters
+(no terminating
+.Dv NUL
+is added).
+The usual skip of leading white space is suppressed.
+To skip white space first, use an explicit space in the format.
+.It Cm \&[
+Matches a nonempty sequence of characters from the specified set
+of accepted characters;
+the next pointer must be a pointer to
+.Em char ,
+and there must be enough room for all the characters in the string,
+plus a terminating
+.Dv NUL
+character.
+The usual skip of leading white space is suppressed.
+The string is to be made up of characters in
+(or not in)
+a particular set;
+the set is defined by the characters between the open bracket
+.Cm [
+character
+and a close bracket
+.Cm ]
+character.
+The set
+.Em excludes
+those characters
+if the first character after the open bracket is a circumflex
+.Cm ^ .
+To include a close bracket in the set,
+make it the first character after the open bracket
+or the circumflex;
+any other position will end the set.
+The hyphen character
+.Cm -
+is also special;
+when placed between two other characters,
+it adds all intervening characters to the set.
+To include a hyphen,
+make it the last character before the final close bracket.
+For instance,
+.Ql [^]0-9-]
+means the set `everything except close bracket, zero through nine,
+and hyphen'.
+The string ends with the appearance of a character not in the
+(or, with a circumflex, in) set
+or when the field width runs out.
+.It Cm p
+Matches a pointer value (as printed by
+.Ql %p
+in
+.Xr printf 3 ) ;
+the next pointer must be a pointer to
+.Em void .
+.It Cm n
+Nothing is expected;
+instead, the number of characters consumed thus far from the input
+is stored through the next pointer,
+which must be a pointer to
+.Em int .
+This is
+.Em not
+a conversion, although it can be suppressed with the
+.Cm *
+flag.
+.El
+.Pp
+For backwards compatibility,
+other conversion characters (except
+.Ql \e0 )
+are taken as if they were
+.Ql %d
+or, if uppercase,
+.Ql %ld ,
+and a `conversion' of
+.Ql %\e0
+causes an immediate return of
+.Dv EOF .
+.Pp
+.Sh RETURN VALUES
+These
+functions
+return
+the number of input items assigned, which can be fewer than provided
+for, or even zero, in the event of a matching failure.
+Zero
+indicates that, while there was input available,
+no conversions were assigned;
+typically this is due to an invalid input character,
+such as an alphabetic character for a
+.Ql %d
+conversion.
+The value
+.Dv EOF
+is returned if an input failure occurs before any conversion such as an
+end-of-file occurs. If an error or end-of-file occurs after conversion
+has begun,
+the number of conversions which were successfully completed is returned.

+.Sh NAME
+.Nm setbuf ,
+.Nm setbuffer ,
+.Nm setlinebuf ,
+.Nm setvbuf
+.Nd stream buffering operations
+.Sh SYNOPSIS
+.Fd #include <stdio.h>
+.Ft void
+.Fn setbuf "FILE *stream" "char *buf"
+.Ft void
+.Fn setbuffer "FILE *stream" "char *buf" "size_t size"
+.Ft int
+.Fn setlinebuf "FILE *stream"
+.Ft int
+.Fn setvbuf "FILE *stream" "char *buf" "int mode" "size_t size"
+.Sh DESCRIPTION
+The three types of buffering available are unbuffered, block buffered,
+and line buffered.
+When an output stream is unbuffered, information appears on the
+destination file or terminal as soon as written;
+when it is block buffered many characters are saved up and written as a block;
+when it is line buffered characters are saved up until a newline is
+output or input is read from any stream attached to a terminal device
+(typically stdin).
+The function
+.Xr fflush 3
+may be used to force the block out early.
+(See 
+.Xr fclose 3 . )
+.Pp
+Normally all files are block buffered.
+When the first
+.Tn I/O
+operation occurs on a file,
+.Xr malloc 3
+is called,
+and an optimally-sized buffer is obtained.
+If a stream refers to a terminal
+(as
+.Em stdout
+normally does) it is line buffered.
+The standard error stream
+.Em stderr
+is always unbuffered.
+.Pp
+The
+.Fn setvbuf
+function
+may be used to alter the buffering behavior of a stream.
+The
+.Fa mode
+parameter must be one of the following three macros:
+.Bl -tag -width _IOFBF -offset indent
+.It Dv _IONBF
+unbuffered
+.It Dv _IOLBF
+line buffered
+.It Dv _IOFBF
+fully buffered
+.El
+.Pp
+The
+.Fa size
+parameter may be given as zero
+to obtain deferred optimal-size buffer allocation as usual.
+If it is not zero,
+then except for unbuffered files, the 
+.Fa buf
+argument should point to a buffer at least
+.Fa size
+bytes long;
+this buffer will be used instead of the current buffer.
+(If the
+.Fa size
+argument
+is not zero but
+.Fa buf
+is
+.Dv NULL ,
+a buffer of the given size will be allocated immediately,
+and released on close.
+This is an extension to ANSI C;
+portable code should use a size of 0 with any
+.Dv NULL
+buffer.)
+.Pp
+The
+.Fn setvbuf
+function may be used at any time,
+but may have peculiar side effects
+(such as discarding input or flushing output)
+if the stream is ``active''.
+Portable applications should call it only once on any given stream,
+and before any 
+.Tn I/O
+is performed.
+.Pp
+The other three calls are, in effect, simply aliases for calls to
+.Fn setvbuf .
+Except for the lack of a return value, the
+.Fn setbuf
+function is exactly equivalent to the call
+.Pp
+.Dl "setvbuf(stream, buf, buf ? _IOFBF : _IONBF, BUFSIZ);"
+.Pp
+The
+.Fn setbuffer
+function
+is the same, except that the size of the buffer is up to the caller,
+rather than being determined by the default
+.Dv BUFSIZ .
+The
+.Fn setlinebuf
+function
+is exactly equivalent to the call:
+.Pp
+.Dl "setvbuf(stream, (char *)NULL, _IOLBF, 0);"
+.Sh RETURN VALUES
+The
+.Fn setvbuf
+function returns 0 on success, or
+.Dv EOF
+if the request cannot be honored
+(note that the stream is still functional in this case).
+.Pp
+The
+.Fn setlinebuf
+function returns what the equivalent
+.Fn setvbuf
+would have returned.
+.Sh SEE ALSO
+.Xr fopen 3 ,
+.Xr fclose 3 ,
+.Xr fread 3 ,
+.Xr malloc 3 ,
+.Xr puts 3 ,
+.Xr printf 3
+.Sh STANDARDS
+The
+.Fn setbuf
+and
+.Fn setvbuf
+functions
+conform to
+.St -ansiC .
+.Sh BUGS
+The
+.Fn setbuffer
+and
+.Fn setlinebuf
+functions are not portable to versions of
+.Bx
+before
+.Bx 4.2 .
+On
+.Bx 4.2
+and
+.Bx 4.3
+systems,
+.Fn setbuf
+always uses a suboptimal buffer size and should be avoided.

+.Sh NAME
+.Nm stdio
+.Nd standard input/output library functions
+.Sh SYNOPSIS
+.Fd #include <stdio.h>
+.Fd FILE *stdin;
+.Fd FILE *stdout;
+.Fd FILE *stderr;
+.Sh DESCRIPTION
+The standard
+.Tn I/O
+library provides a simple and efficient buffered stream
+.Tn I/O
+interface.
+Input and output is mapped into logical data streams
+and the physical
+.Tn I/O
+characteristics are concealed. The functions and macros are listed
+below; more information is available from the individual man pages.
+.Pp
+A stream is associated with an external file (which may be a physical
+device) by
+.Em opening
+a file, which may involve creating a new file. Creating an
+existing file causes its former contents to be discarded.
+If a file can support positioning requests (such as a disk file, as opposed
+to a terminal) then a
+.Em file position indicator
+associated with the stream is positioned at the start of the file (byte
+zero), unless the file is opened with append mode. If append mode
+is used, the position indicator will be placed the end-of-file.
+The position indicator is maintained by subsequent reads, writes
+and positioning requests. All input occurs as if the characters
+were read by successive calls to the
+.Xr fgetc 3
+function; all output takes place as if all characters were
+read by successive calls to the
+.Xr fputc 3
+function.
+.Pp
+A file is disassociated from a stream by
+.Em closing
+the file.
+Output streams are flushed (any unwritten buffer contents are transferred
+to the host environment) before the stream is disassociated from the file.
+The value of a pointer to a
+.Dv FILE
+object is indeterminate after a file is closed (garbage).
+.Pp
+A file may be subsequently reopened, by the same or another program
+execution, and its contents reclaimed or modified (if it can be repositioned
+at the start).  If the main function returns to its original caller, or
+the
+.Xr exit 3
+function is called, all open files are closed (hence all output
+streams are flushed) before program termination.  Other methods
+of program termination, such as
+.Xr abort 3
+do not bother about closing files properly.
+.Pp
+This implementation needs and makes
+no distinction between
+.Dq text
+and
+.Dq binary
+streams.
+In effect, all streams are binary.
+No translation is performed and no extra padding appears on any stream.
+.Pp
+At program startup, three streams are predefined and need not be
+opened explicitly:
+.Bl -bullet -compact -offset indent
+.It
+.Em standard input 
+(for reading conventional input),
+.It
+.Em standard output 
+(for writing conventional output), and
+.It
+.Em standard error
+(for writing diagnostic output).
+.El
+These streams are abbreviated
+.Em stdin , stdout
+and
+.Em stderr .
+Initially, the standard error stream
+is unbuffered; the standard input and output streams are
+fully buffered if and only if the streams do not refer to
+an interactive or
+.Dq terminal
+device, as determined by the
+.Xr isatty 3
+function.
+In fact,
+.Em all
+freshly-opened streams that refer to terminal devices
+default to line buffering, and
+pending output to such streams is written automatically
+whenever an such an input stream is read.
+Note that this applies only to
+.Dq "true reads" ;
+if the read request can be satisfied by existing buffered data,
+no automatic flush will occur.
+In these cases,
+or when a large amount of computation is done after printing
+part of a line on an output terminal, it is necessary to
+.Xr fflush 3
+the standard output before going off and computing so that the output
+will appear.
+Alternatively, these defaults may be modified via the
+.Xr setvbuf 3
+function.
+.Pp
+The
+.Nm stdio
+library is a part of the library
+.Xr libc
+and routines are automatically loaded as needed by the compilers
+.Xr cc 1
+and
+.Xr pc 1 .
+The
+.Tn SYNOPSIS
+sections of the following manual pages indicate which include files
+are to be used, what the compiler declaration for the function
+looks like and which external variables are of interest.
+.Pp
+The following are defined as macros;
+these names may not be re-used
+without first removing their current definitions with
+.Dv #undef :
+.Dv BUFSIZ ,
+.Dv EOF ,
+.Dv FILENAME_MAX ,
+.DV FOPEN_MAX ,
+.Dv L_cuserid ,
+.Dv L_ctermid ,
+.Dv L_tmpnam,
+.Dv NULL ,
+.Dv SEEK_END ,
+.Dv SEEK_SET ,
+.Dv SEE_CUR ,
+.Dv TMP_MAX ,
+.Dv clearerr ,
+.Dv feof ,
+.Dv ferror ,
+.Dv fileno ,
+.Dv freopen ,
+.Dv fwopen ,
+.Dv getc ,
+.Dv getchar ,
+.Dv putc ,
+.Dv putchar ,
+.Dv stderr ,
+.Dv stdin ,
+.Dv stdout .
+Function versions of the macro functions
+.Xr feof ,
+.Xr ferror ,
+.Xr clearerr ,
+.Xr fileno ,
+.Xr getc ,
+.Xr getchar ,
+.Xr putc ,
+and
+.Xr putchar
+exist and will be used if the macros
+definitions are explicitly removed.
+.Sh SEE ALSO
+.Xr open 2 ,
+.Xr close 2 ,
+.Xr read 2 ,
+.Xr write 2
+.Sh BUGS
+The standard buffered functions do not interact well with certain other
+library and system functions, especially
+.Xr vfork
+and
+.Xr abort .
+.Sh STANDARDS
+The

+.Os
+.Sh NAME
+.Nm tempnam ,
+.Nm tmpfile ,
+.Nm tmpnam
+.Nd temporary file routines
+.Sh SYNOPSIS
+.Fd #include <stdio.h>
+.Ft FILE *
+.Fn tmpfile void
+.Ft char *
+.Fn tmpnam "char *str"
+.Ft char *
+.Fn tempnam "const char *tmpdir" "const char *prefix"
+.Sh DESCRIPTION
+The
+.Fn tmpfile
+function
+returns a pointer to a stream associated with a file descriptor returned
+by the routine
+.Xr mkstemp 3 .
+The created file is unlinked before
+.Fn tmpfile
+returns, causing the file to be automatically deleted when the last
+reference to it is closed.
+The file is opened with the access value
+.Ql w+ .
+.Pp
+The
+.Fn tmpnam
+function
+returns a pointer to a file name, in the
+.Dv P_tmpdir
+directory, which
+did not reference an existing file at some indeterminate point in the
+past.
+.Dv P_tmpdir
+is defined in the include file
+.Aq Pa stdio.h .
+If the argument
+.Fa s
+is
+.Pf non- Dv NULL ,
+the file name is copied to the buffer it references.
+Otherwise, the file name is copied to a static buffer.
+In either case,
+.Fn tmpnam
+returns a pointer to the file name.
+.Pp
+The buffer referenced by 
+.Fa s
+is expected to be at least
+.Dv L_tmpnam
+bytes in length.
+.Dv L_tmpnam
+is defined in the include file
+.Aq Pa stdio.h .
+.Pp
+The
+.Fn tempnam
+function
+is similar to
+.Fn tmpnam ,
+but provides the ability to specify the directory which will
+contain the temporary file and the file name prefix.
+.Pp
+The environment variable
+.Ev TMPDIR
+(if set), the argument
+.Fa tmpdir
+(if
+.Pf non- Dv NULL ) ,
+the directory
+.Dv P_tmpdir ,
+and the directory
+.Pa /tmp
+are tried, in the listed order, as directories in which to store the
+temporary file.
+.Pp
+The argument
+.Fa prefix ,
+if
+.Pf non- Dv NULL ,
+is used to specify a file name prefix, which will be the
+first part of the created file name.
+.Fn Tempnam
+allocates memory in which to store the file name; the returned pointer
+may be used as a subsequent argument to
+.Xr free 3 .
+.Sh RETURN VALUES
+The
+.Fn tmpfile
+function
+returns a pointer to an open file stream on success, and a
+.Dv NULL
+pointer
+on error.
+.Pp
+The
+.Fn tmpnam
+and
+.Fn tempfile
+functions
+return a pointer to a file name on success, and a
+.Dv NULL
+pointer
+on error.
+.Sh ERRORS
+The
+.Fn tmpfile
+function
+may fail and set the global variable
+.Va errno
+for any of the errors specified for the library functions
+.Xr fdopen 3
+or
+.Xr mkstemp 3 .
+.Pp
+The
+.Fn tmpnam
+function
+may fail and set
+.Va errno
+for any of the errors specified for the library function
+.Xr mktemp 3 .
+.Pp
+The
+.Fn tempnam
+function
+may fail and set
+.Va errno
+for any of the errors specified for the library functions
+.Xr malloc 3
+or
+.Xr mktemp 3 .
+.Sh SEE ALSO
+.Xr mkstemp 3 ,
+.Xr mktemp 3
+.Sh STANDARDS
+The
+.Fn tmpfile
+and
+.Fn tmpnam
+functions
+conform to
+.St -ansiC .
+.Sh BUGS
+These interfaces are provided for System V and
+.Tn ANSI
+compatibility only.
+The
+.Xr mkstemp 3
+interface is strongly preferred.
+.Pp
+There are four important problems with these interfaces (as well as
+with the historic
+.Xr mktemp 3
+interface).
+First, there is an obvious race between file name selection and file
+creation and deletion.
+Second, most historic implementations provide only a limited number
+of possible temporary file names (usually 26) before file names will
+start being recycled.
+Third, the System V implementations of these functions (and of
+.Xr mktemp )
+use the
+.Xr access 2
+function to determine whether or not the temporary file may be created.
+This has obvious ramifications for setuid or setgid programs, complicating
+the portable use of these interfaces in such programs.
+Finally, there is no specification of the permissions with which the
+temporary files are created.
+.Pp
+This implementation does not have these flaws, but portable software
+cannot depend on that.
+In particular, the
+.Fn tmpfile
+interface should not be used in software expected to be used on other systems
+if there is any possibility that the user does not wish the temporary file to
+be publicly readable and writable.

+A successful intervening call, using the same stream, to one of the file
+positioning functions
+.Po
+.Xr fseek 3 ,
+.Xr fsetpos 3 ,
+or
+.Xr rewind 3
+.Pc
+will discard the pushed back characters.
+.Pp
+One character of push-back is guaranteed,
+but as long as there is
+sufficient memory, an effectively infinite amount of pushback is allowed.
+.Pp
+If a character is successfully pushed-back,
+the end-of-file indicator for the stream is cleared.
+.Sh RETURN VALUES
+The
+.Fn ungetc
+function
+returns
+the character pushed-back after the conversion, or
+.Dv EOF
+if the operation fails.
+If the value of the argument
+.Fa c
+character equals
+.Dv EOF ,
+the operation will fail and the stream will remain unchanged.
+.Sh SEE ALSO
+.Xr getc 3 ,
+.Xr fseek 3 ,
+.Xr setvbuf 3
+.Sh STANDARDS
+The
+.Fn ungetc
+function conforms to
+.St -ansiC .

+.Sh DESCRIPTION
+The
+.Fn bsearch
+function searches an array of
+.Fa nmemb
+objects, the initial member of which is 
+pointed to by
+.Fa base ,
+for a member that matches the object pointed to by

+The contents of the array should be in ascending sorted order according

+The
+.Fa compar

+less than, equal to, or greater than zero if the
+.Fa key
+object is found, respectively, to be less than, to match, or be
+greater than the array member.
+.Sh RETURN VALUES
+The
+.Fn bsearch

+.Sh NAME
+.Nm getopt
+.Nd get option character from command line argument list
+.Sh SYNOPSIS
+.Fd #include <unistd.h>
+.Vt extern char *optarg;
+.Vt extern int   optind;
+.Vt extern int   optopt;
+.Vt extern int   opterr;
+.Vt extern int   optreset;
+.Ft int
+.Fn getopt "int argc" "char * const *argv" "const char *optstring"
+.Sh DESCRIPTION
+The
+.Fn getopt
+function incrementally parses a command line argument list
+.Fa argv
+and returns the next
+.Em known
+option character.
+An option character is
+.Em known
+if it has been specified in the string of accepted option characters,
+.Fa optstring .
+.Pp
+The option string
+.Fa optstring
+may contain the following elements: individual characters, and
+characters followed by a colon to indicate an option argument
+is to follow.
+For example, an option string
+.Li "\&""x""
+recognizes an option
+.Dq Fl x ,
+and an option string
+.Li "\&""x:""
+recognizes an option and argument
+.Dq Fl x Ar argument .
+It does not matter to
+.Fn getopt
+if a following argument has leading white space.
+.Pp
+On return from
+.Fn getopt ,
+.Va optarg
+points to an option argument, if it is anticipated,
+and the variable
+.Va optind
+contains the index to the next
+.Fa argv
+argument for a subsequent call
+to
+.Fn getopt .
+The variable
+.Va optopt
+saves the last
+.Em known
+option character returned by
+.Fn getopt .
+.Pp
+The variable
+.Va opterr
+and
+.Va optind
+are both initialized to 1.
+The
+.Va optind
+variable may be set to another value before a set of calls to
+.Fn getopt
+in order to skip over more or less argv entries.
+.Pp
+In order to use
+.Fn getopt
+to evaluate multiple sets of arguments, or to evaluate a single set of
+arguments multiple times,
+the variable
+.Va optreset
+must be set to 1 before the second and each additional set of calls to
+.Fn getopt ,
+and the variable
+.Va optind
+must be reinitialized.
+.Pp
+The
+.Fn getopt
+function
+returns \-1
+when the argument list is exhausted, or a non-recognized
+option is encountered.
+The interpretation of options in the argument list may be cancelled
+by the option
+.Ql --
+(double dash) which causes
+.Fn getopt
+to signal the end of argument processing and returns \-1.
+When all options have been processed (i.e., up to the first non-option
+argument),
+.Fn getopt
+returns \-1.
+.Sh DIAGNOSTICS
+If the
+.Fn getopt
+function encounters a character not found in the string
+.Va optarg
+or detects
+a missing option argument it writes an error message and returns
+.Ql ?
+to the
+.Em stderr .
+Setting
+.Va opterr
+to a zero will disable these error messages.
+If
+.Va optstring 
+has a leading 
+.Ql \&:
+then a missing option argument causes a
+.Ql \&:
+to be returned in addition to suppressing any error messages.
+.Pp
+Option arguments are allowed to begin with
+.Dq Li \- ;
+this is reasonable but
+reduces the amount of error checking possible.
+.Sh EXTENSIONS
+The
+.Va optreset
+variable was added to make it possible to call the
+.Fn getopt
+function multiple times.
+This is an extension to the
+.St -p1003.2
+specification.
+.Sh EXAMPLE
+.Bd -literal -compact
+extern char *optarg;
+extern int optind;
+int bflag, ch, fd;
+
+bflag = 0;
+while ((ch = getopt(argc, argv, "bf:")) != -1)
+	switch(ch) {
+	case 'b':
+		bflag = 1;
+		break;
+	case 'f':
+		if ((fd = open(optarg, O_RDONLY, 0)) < 0) {
+			(void)fprintf(stderr,
+			    "myname: %s: %s\en", optarg, strerror(errno));
+			exit(1);
+		}
+		break;
+	case '?':
+	default:
+		usage();
+}
+argc -= optind;
+argv += optind;
+.Ed
+.Sh HISTORY
+The
+.Fn getopt
+function appeared
+.Bx 4.3 .
+.Sh BUGS
+The
+.Fn getopt
+function was once specified to return
+.Dv EOF 
+instead of \-1.
+This was changed by
+.St -p1003.2-92
+to decouple 
+.Fn getopt
+from 
+.Pa <stdio.h> .
+.Pp
+A single dash
+.Dq Li -
+may be specified as an character in
+.Fa optstring ,
+however it should
+.Em never
+have an argument associated with it.
+This allows
+.Fn getopt
+to be used with programs that expect
+.Dq Li -
+as an option flag.
+This practice is wrong, and should not be used in any current development.
+It is provided for backward compatibility
+.Em only .
+By default, a single dash causes
+.Fn getopt
+to return \-1.
+This is, we believe, compatible with System V.
+.Pp
+It is also possible to handle digits as option letters.
+This allows
+.Fn getopt
+to be used with programs that expect a number
+.Pq Dq Li \&-\&3
+as an option.
+This practice is wrong, and should not be used in any current development.
+It is provided for backward compatibility
+.Em only .
+The following code fragment works in most cases.
+.Bd -literal -offset indent
+int length;
+char *p;
+
+while ((c = getopt(argc, argv, "0123456789")) != -1)
+	switch (c) {
+	case '0': case '1': case '2': case '3': case '4':
+	case '5': case '6': case '7': case '8': case '9':
+		p = argv[optind - 1];
+		if (p[0] == '-' && p[1] == ch && !p[2])
+			length = atoi(++p);
+		else
+			length = atoi(argv[optind] + 1);

+.Sh NAME
+.Nm malloc
+.Nd general memory allocation function
+.Sh SYNOPSIS
+.Fd #include <stdlib.h>
+.Ft void *
+.Fn malloc "size_t size"
+.Sh DESCRIPTION
+The
+.Fn malloc
+function allocates uninitialized space for an object whose
+size is specified by
+.Fa size .
+The
+.Fn malloc
+function maintains multiple lists of free blocks according to size, allocating
+space from the appropriate list.
+.Pp
+The allocated space is
+suitably aligned (after possible pointer
+coercion) for storage of any type of object. If the space is of
+.Em pagesize
+or larger, the memory returned will be page-aligned.
+.Sh RETURN VALUES
+The
+.Fn malloc
+function returns
+a pointer to the allocated space if successful; otherwise
+a null pointer is returned.
+.Sh SEE ALSO
+.Xr brk 2 ,
+.Xr getpagesize 2 ,
+.Xr free 3 ,
+.Xr calloc 3 ,
+.Xr alloca 3 ,
+.Xr realloc 3 ,
+.Xr memory 3
+.Sh STANDARDS
+The
+.Fn malloc
+function conforms to
+.St -ansiC .
+.Sh BUGS
+The current implementation of
+.Xr malloc
+does not always fail gracefully when system
+memory limits are approached.
+It may fail to allocate memory when larger free blocks could be broken
+up, or when limits are exceeded because the size is rounded up.
+It is optimized for sizes that are powers of two.

+.Sh NAME
+.Nm qsort, heapsort, mergesort
+.Nd sort functions
+.Sh SYNOPSIS
+.Fd #include <stdlib.h>
+.Ft void
+.Fn qsort "void *base" "size_t nmemb" "size_t size" "int (*compar)(const void *, const void *)"
+.Ft int
+.Fn heapsort "void *base" "size_t nmemb" "size_t size" "int (*compar)(const void *, const void *)"
+.Ft int
+.Fn mergesort "void *base" "size_t nmemb" "size_t size" "int (*compar)(const void *, const void *)"
+.Sh DESCRIPTION
+The
+.Fn qsort
+function is a modified partition-exchange sort, or quicksort.
+The
+.Fn heapsort
+function is a modified selection sort.
+The
+.Fn mergesort
+function is a modified merge sort with exponential search
+intended for sorting data with pre-existing order.
+.Pp
+The
+.Fn qsort
+and
+.Fn heapsort
+functions sort an array of
+.Fa nmemb
+objects, the initial member of which is pointed to by
+.Fa base .
+The size of each object is specified by
+.Fa size .
+.Fn Mergesort
+behaves similarly, but
+.Em requires
+that
+.Fa size
+be greater than
+.Dq "sizeof(void *) / 2" .
+.Pp
+The contents of the array
+.Fa base
+are sorted in ascending order according to
+a comparison function pointed to by
+.Fa compar ,
+which requires two arguments pointing to the objects being
+compared.
+.Pp
+The comparison function must return an integer less than, equal to, or
+greater than zero if the first argument is considered to be respectively
+less than, equal to, or greater than the second.
+.Pp
+The functions
+.Fn qsort
+and
+.Fn heapsort
+are
+.Em not
+stable, that is, if two members compare as equal, their order in
+the sorted array is undefined.
+The function
+.Fn mergesort
+is stable.
+.Pp
+The
+.Fn qsort
+function is an implementation of C.A.R. Hoare's ``quicksort'' algorithm,
+a variant of partition-exchange sorting; in particular, see D.E. Knuth's
+Algorithm Q.
+.Fn Qsort
+takes O N lg N average time.
+This implementation uses median selection to avoid its
+O N**2 worst-case behavior.
+.Pp
+The
+.Fn heapsort
+function is an implementation of J.W.J. William's ``heapsort'' algorithm,
+a variant of selection sorting; in particular, see D.E. Knuth's Algorithm H.
+.Fn Heapsort
+takes O N lg N worst-case time.
+Its
+.Em only
+advantage over
+.Fn qsort
+is that it uses almost no additional memory; while
+.Fn qsort
+does not allocate memory, it is implemented using recursion.
+.Pp
+The function
+.Fn mergesort
+requires additional memory of size
+.Fa nmemb *
+.Fa size 
+bytes; it should be used only when space is not at a premium.
+.Fn Mergesort
+is optimized for data with pre-existing order; its worst case
+time is O N lg N; its best case is O N.
+.Pp
+Normally,
+.Fn qsort
+is faster than
+.Fn mergesort
+is faster than
+.Fn heapsort .
+Memory availability and pre-existing order in the data can make this
+untrue.
+.Sh RETURN VALUES
+The
+.Fn qsort
+function
+returns no value.
+.Pp
+Upon successful completion,
+.Fn heapsort
+and
+.Fn mergesort
+return 0.
+Otherwise, they return \-1 and the global variable
+.Va errno
+is set to indicate the error.
+.Sh ERRORS
+The
+.Fn heapsort
+function succeeds unless:
+.Bl -tag -width Er
+.It Bq Er EINVAL
+The
+.Fa size
+argument is zero, or,
+the
+.Fa size
+argument to
+.Fn mergesort
+is less than
+.Dq "sizeof(void *) / 2" .
+.It Bq Er ENOMEM
+.Fn Heapsort
+or
+.Fn mergesort
+were unable to allocate memory.
+.El
+.Sh COMPATIBILITY
+Previous versions of
+.Fn qsort
+did not permit the comparison routine itself to call
+.Fn qsort 3 .
+This is no longer true.

+.Nd radix sort
+.Sh SYNOPSIS
+.Fd #include <limits.h>
+.Fd #include <stdlib.h>
+.Ft int
+.Fn radixsort "u_char **base" "int nmemb" "u_char *table" "u_int endbyte"
+.Ft int
+.Fn sradixsort "u_char **base" "int nmemb" "u_char *table" "u_int endbyte"
+.Sh DESCRIPTION
+The
+.Fn radixsort
+and
+.Fn sradixsort
+functions
+are implementations of radix sort.
+.Pp
+These functions sort an array of pointers to byte strings, the initial
+member of which is referenced by
+.Fa base .
+The byte strings may contain any values; the end of each string
+is denoted by the user-specified value
+.Fa endbyte .
+.Pp
+Applications may specify a sort order by providing the
+.Fa table
+argument.
+If
+.Pf non- Dv NULL , 
+.Fa table
+must reference an array of
+.Dv UCHAR_MAX
++ 1 bytes which contains the sort
+weight of each possible byte value.
+The end-of-string byte must have a sort weight of 0 or 255
+(for sorting in reverse order).
+More than one byte may have the same sort weight.
+The
+.Fa table
+argument
+is useful for applications which wish to sort different characters
+equally, for example, providing a table with the same weights
+for A-Z as for a-z will result in a case-insensitive sort.
+If
+.Fa table
+is NULL, the contents of the array are sorted in ascending order
+according to the
+.Tn ASCII
+order of the byte strings they reference and
+.Fa endbyte
+has a sorting weight of 0.
+.Pp
+The
+.Fn sradixsort
+function is stable, that is, if two elements compare as equal, their
+order in the sorted array is unchanged.
+The
+.Fn sradixsort
+function uses additional memory sufficient to hold
+.Fa nmemb
+pointers.
+.Pp
+The
+.Fn radixsort
+function is not stable, but uses no additional memory.
+.Pp
+These functions are variants of most-significant-byte radix sorting; in
+particular, see D.E. Knuth's Algorithm R and section 5.2.5, exercise 10.
+They take linear time relative to the number of bytes in the strings.
+.Sh RETURN VALUES
+Upon successful completion 0 is returned.
+Otherwise, \-1 is returned and the global variable 
+.Va errno
+is set to indicate the error.
+.Sh ERRORS
+.Bl -tag -width Er
+.It Bq Er EINVAL
+The value of the
+.Fa endbyte
+element of
+.Fa table
+is not 0 or 255.
+.El
+.Pp
+Additionally, the
+.Fn sradixsort
+function
+may fail and set
+.Va errno
+for any of the errors specified for the library routine
+.Xr malloc 3 .

+.Sh DESCRIPTION
+The
+.Fn rand48
+family of functions generates pseudo-random numbers using a linear
+congruential algorithm working on integers 48 bits in size. The
+particular formula employed is
+r(n+1) = (a * r(n) + c) mod m
+where the default values are
+for the multiplicand a = 0xfdeece66d = 25214903917 and
+the addend c = 0xb = 11. The modulus is always fixed at m = 2 ** 48.
+r(n) is called the seed of the random number generator.
+.Pp
+For all the six generator routines described next, the first
+computational step is to perform a single iteration of the algorithm.
+.Pp
+.Fn drand48
+and
+.Fn erand48
+return values of type double. The full 48 bits of r(n+1) are
+loaded into the mantissa of the returned value, with the exponent set
+such that the values produced lie in the interval [0.0, 1.0).
+.Pp
+.Fn lrand48
+and
+.Fn nrand48
+return values of type long in the range
+[0, 2**31-1]. The high-order (31) bits of
+r(n+1) are loaded into the lower bits of the returned value, with
+the topmost (sign) bit set to zero.
+.Pp
+.Fn mrand48
+and
+.Fn jrand48
+return values of type long in the range
+[-2**31, 2**31-1]. The high-order (32) bits of
+r(n+1) are loaded into the returned value.
+.Pp
+.Fn drand48 ,
+.Fn lrand48 ,
+and
+.Fn mrand48
+use an internal buffer to store r(n). For these functions
+the initial value of r(0) = 0x1234abcd330e = 20017429951246.
+.Pp
+On the other hand,
+.Fn erand48 ,
+.Fn nrand48 ,
+and
+.Fn jrand48
+use a user-supplied buffer to store the seed r(n),
+which consists of an array of 3 shorts, where the zeroth member
+holds the least significant bits.
+.Pp
+All functions share the same multiplicand and addend.
+.Pp
+.Fn srand48
+is used to initialize the internal buffer r(n) of
+.Fn drand48 ,
+.Fn lrand48 ,
+and
+.Fn mrand48
+such that the 32 bits of the seed value are copied into the upper 32 bits
+of r(n), with the lower 16 bits of r(n) arbitrarily being set to 0x330e.
+Additionally, the constant multiplicand and addend of the algorithm are
+reset to the default values given above.
+.Pp
+.Fn seed48
+also initializes the internal buffer r(n) of
+.Fn drand48 ,
+.Fn lrand48 ,
+and
+.Fn mrand48 ,
+but here all 48 bits of the seed can be specified in an array of 3 shorts,
+where the zeroth member specifies the lowest bits. Again,
+the constant multiplicand and addend of the algorithm are
+reset to the default values given above.
+.Fn seed48
+returns a pointer to an array of 3 shorts which contains the old seed.
+This array is statically allocated, thus its contents are lost after
+each new call to
+.Fn seed48 .
+.Pp
+Finally,
+.Fn lcong48
+allows full control over the multiplicand and addend used in
+.Fn drand48 ,
+.Fn erand48 ,
+.Fn lrand48 ,
+.Fn nrand48 ,
+.Fn mrand48 ,
+and
+.Fn jrand48 ,
+and the seed used in
+.Fn drand48 ,
+.Fn lrand48 ,
+and
+.Fn mrand48 .
+An array of 7 shorts is passed as parameter; the first three shorts are
+used to initialize the seed; the second three are used to initialize the
+multiplicand; and the last short is used to initialize the addend.
+It is thus not possible to use values greater than 0xffff as the addend.
+.Pp
+Note that all three methods of seeding the random number generator
+always also set the multiplicand and addend for any of the six
+generator calls.

+.Sh DESCRIPTION
+The
+.Fn random
+function
+uses a non-linear additive feedback random number generator employing a
+default table of size 31 long integers to return successive pseudo-random
+numbers in the range from 0 to
+.if t 2\u\s731\s10\d\(mi1.
+.if n (2**31)\(mi1.
+The period of this random number generator is very large, approximately
+.if t 16\(mu(2\u\s731\s10\d\(mi1).
+.if n 16*((2**31)\(mi1).
+.Pp
+The
+.Fn random Ns / Fn srandom
+have (almost) the same calling sequence and initialization properties as
+.Xr rand 3 Ns / Xr srand 3 .
+The difference is that
+.Xr rand
+produces a much less random sequence \(em in fact, the low dozen bits
+generated by rand go through a cyclic pattern.  All the bits generated by
+.Fn random
+are usable.  For example,
+.Sq Li random()&01
+will produce a random binary
+value.
+.Pp
+Unlike
+.Xr srand ,
+.Fn srandom
+does not return the old seed; the reason for this is that the amount of
+state information used is much more than a single word.  (Two other
+routines are provided to deal with restarting/changing random
+number generators).  Like
+.Xr rand 3 ,
+however,
+.Fn random
+will by default produce a sequence of numbers that can be duplicated
+by calling
+.Fn srandom
+with 
+.Ql 1
+as the seed.
+.Pp
+The
+.Fn initstate
+routine allows a state array, passed in as an argument, to be initialized
+for future use.  The size of the state array (in bytes) is used by
+.Fn initstate
+to decide how sophisticated a random number generator it should use \(em the
+more state, the better the random numbers will be.
+(Current "optimal" values for the amount of state information are
+8, 32, 64, 128, and 256 bytes; other amounts will be rounded down to
+the nearest known amount.  Using less than 8 bytes will cause an error.)
+The seed for the initialization (which specifies a starting point for
+the random number sequence, and provides for restarting at the same
+point) is also an argument.
+The
+.Fn initstate
+function
+returns a pointer to the previous state information array.
+.Pp
+Once a state has been initialized, the
+.Fn setstate
+routine provides for rapid switching between states.
+The
+.Fn setstate
+function
+returns a pointer to the previous state array; its
+argument state array is used for further random number generation
+until the next call to
+.Fn initstate
+or
+.Fn setstate .
+.Pp
+Once a state array has been initialized, it may be restarted at a
+different point either by calling
+.Fn initstate
+(with the desired seed, the state array, and its size) or by calling
+both
+.Fn setstate
+(with the state array) and
+.Fn srandom
+(with the desired seed).
+The advantage of calling both
+.Fn setstate
+and
+.Fn srandom
+is that the size of the state array does not have to be remembered after
+it is initialized.
+.Pp
+With 256 bytes of state information, the period of the random number
+generator is greater than
+.if t 2\u\s769\s10\d,
+.if n 2**69
+which should be sufficient for most purposes.
+.Sh AUTHOR
+Earl T. Cohen
+.Sh DIAGNOSTICS
+If
+.Fn initstate
+is called with less than 8 bytes of state information, or if
+.Fn setstate
+detects that the state information has been garbled, error
+messages are printed on the standard error output.

+ * random.c:
+ *
+ * An improved random number generation package.  In addition to the standard
+ * rand()/srand() like interface, this package also has a special state info
+ * interface.  The initstate() routine is called with a seed, an array of
+ * bytes, and a count of how many bytes are being passed in; this array is
+ * then initialized to contain information for random number generation with
+ * that much state information.  Good sizes for the amount of state
+ * information are 32, 64, 128, and 256 bytes.  The state can be switched by
+ * calling the setstate() routine with the same array as was initiallized
+ * with initstate().  By default, the package runs with 128 bytes of state
+ * information and generates far better random numbers than a linear
+ * congruential generator.  If the amount of state information is less than
+ * 32 bytes, a simple linear congruential R.N.G. is used.
+ *
+ * Internally, the state information is treated as an array of longs; the
+ * zeroeth element of the array is the type of R.N.G. being used (small
+ * integer); the remainder of the array is the state information for the
+ * R.N.G.  Thus, 32 bytes of state information will give 7 longs worth of
+ * state information, which will allow a degree seven polynomial.  (Note:
+ * the zeroeth word of state information also has some other information
+ * stored in it -- see setstate() for details).
+ * 
+ * The random number generation technique is a linear feedback shift register
+ * approach, employing trinomials (since there are fewer terms to sum up that
+ * way).  In this approach, the least significant bit of all the numbers in
+ * the state table will act as a linear feedback shift register, and will
+ * have period 2^deg - 1 (where deg is the degree of the polynomial being
+ * used, assuming that the polynomial is irreducible and primitive).  The
+ * higher order bits will have longer periods, since their values are also
+ * influenced by pseudo-random carries out of the lower bits.  The total
+ * period of the generator is approximately deg*(2**deg - 1); thus doubling
+ * the amount of state information has a vast influence on the period of the
+ * generator.  Note: the deg*(2**deg - 1) is an approximation only good for
+ * large deg, when the period of the shift register is the dominant factor.
+ * With deg equal to seven, the period is actually much longer than the
+ * 7*(2**7 - 1) predicted by this formula.
+ */
+
+/*
+ * For each of the currently supported random number generators, we have a
+ * break value on the amount of state information (you need at least this
+ * many bytes of state info to support this random number generator), a degree
+ * for the polynomial (actually a trinomial) that the R.N.G. is based on, and
+ * the separation between the two lower order coefficients of the trinomial.

+.Sh NAME

+.Nd reallocation of memory function
+.Sh SYNOPSIS
+.Fd #include <stdlib.h>
+.Ft void *
+.Fn realloc "void *ptr" "size_t size"
+.Sh DESCRIPTION
+The
+.Fn realloc
+function changes the size of the object pointed to by
+.Fa ptr
+to the size specified by
+.Fa size .
+The contents of the object are unchanged up to the lesser
+of the new and old sizes.
+If the new size is larger, the value of the newly allocated portion
+of the object is indeterminate.
+If
+.Fa ptr
+is a null pointer, the
+.Fn realloc
+function behaves like the
+.Xr malloc 3
+function for the specified size.
+Otherwise, if
+.Fa ptr
+does not match a pointer earlier returned by the
+.Xr calloc 3 ,
+.Xr malloc 3 ,
+or 
+.Fn realloc
+function, or if the space has been deallocated
+by a call to the
+.Xr free
+or
+.Fn realloc
+function, unpredictable and usually detrimental
+behavior will occur.
+If the space cannot be allocated, the object 
+pointed to by
+.Fa ptr
+is unchanged.
+If
+.Fa size
+is zero and
+.Fa ptr
+is not a null pointer, the object it points to is freed.
+.Pp
+The
+.Fn realloc
+function returns either a null pointer or a pointer
+to the possibly moved allocated space.
+.Sh SEE ALSO
+.Xr alloca 3 ,
+.Xr calloc 3 ,
+.Xr free 3 ,
+.Xr malloc 3 ,
+.Sh STANDARDS
+The
+.Fn realloc
+function conforms to
+.St -ansiC .

+.Sh NAME
+.Nm realpath
+.Nd returns the canonicalized absolute pathname
+.Sh SYNOPSIS
+.Fd #include <sys/param.h>
+.Fd #include <stdlib.h>
+.Ft "char *"
+.Fn realpath "const char *pathname" "char resolvedname[MAXPATHLEN]"
+.Sh DESCRIPTION
+The
+.Fn realpath
+function resolves all symbolic links, extra
+.Dq /
+characters and references to
+.Pa /./
+and
+.Pa /../
+in
+.Fa pathname ,
+and copies the resulting absolute pathname into
+the memory referenced by
+.Fa resolvedname .
+The
+.Fa resolvedname
+argument
+.Em must
+refer to a buffer capable of storing at least
+.Dv MAXPATHLEN
+characters.
+.Pp
+The 
+.Fn realpath
+function will resolve both absolute and relative paths
+and return the absolute pathname corresponding to
+.Fa pathname .
+All but the last component of
+.Fa pathname
+must exist when
+.Fn realpath
+is called.
+.Sh "RETURN VALUES"
+The
+.Fn realpath
+function returns
+.Fa resolved_name
+on success.
+If an error occurs,
+.Fn realpath
+returns
+.Dv NULL ,
+and
+.Fa resolved_name
+contains the pathname which caused the problem.
+.Sh ERRORS
+The function
+.Fn realpath
+may fail and set the external variable
+.Va errno
+for any of the errors specified for the library functions
+.Xr chdir 2 ,
+.Xr close 2 ,
+.Xr fchdir 2 ,
+.Xr lstat 2 ,
+.Xr open 2 ,
+.Xr readlink 2
+and
+.Xr getcwd 3 .
+.Sh CAVEATS
+This implementation of
+.Fn realpath
+differs slightly from the Solaris implementation.
+The
+.Bx 4.4
+version always returns absolute pathnames,
+whereas the Solaris implementation will,
+under certain circumstances, return a relative
+.Fa resolved_path
+when given a relative
+.Fa pathname .
+.Sh "SEE ALSO"
+.Xr getcwd 3
+.Sh HISTORY
+The
+.Fn realpath
+function call first appeared in
+.Bx 4.4 .

+.Sh SYNOPSIS
+.Fd #include <stdlib.h>
+.Ft double
+.Fn strtod "const char *nptr" "char **endptr"
+.Sh DESCRIPTION
+The
+.Fn strtod
+function converts the initial portion of the string 
+pointed to by
+.Fa nptr
+to
+.Em double
+representation.
+.Pp
+The expected form of the string is an optional plus (``+'') or minus
+sign (``-'') followed by a sequence of digits optionally containing
+a decimal-point character, optionally followed by an exponent.
+An exponent consists of an ``E'' or ``e'', followed by an optional plus
+or minus sign, followed by a sequence of digits.
+.Pp
+Leading white-space characters in the string (as defined by the
+.Xr isspace 3
+function) are skipped.
+.Sh RETURN VALUES
+The
+.Fn strtod
+function returns the converted value, if any.
+.Pp
+If
+.Fa endptr
+is not
+.Dv NULL ,
+a pointer to the character after the last character used
+in the conversion is stored in the location referenced by
+.Fa endptr .
+.Pp
+If no conversion is performed, zero is returned and the value of
+.Fa nptr
+is stored in the location referenced by
+.Fa endptr .
+.Pp
+If the correct value would cause overflow, plus or minus
+.Dv HUGE_VAL
+is returned (according to the sign of the value), and
+.Dv ERANGE
+is stored in
+.Va errno .
+If the correct value would cause underflow, zero is
+returned and
+.Dv ERANGE
+is stored in 
+.Va errno .

+/* strtod for IEEE-, VAX-, and IBM-arithmetic machines.
+ *
+ * This strtod returns a nearest machine number to the input decimal
+ * string (or sets errno to ERANGE).  With IEEE arithmetic, ties are
+ * broken by the IEEE round-even rule.  Otherwise ties are broken by
+ * biased rounding (add half and chop).
+ *
+ * Inspired loosely by William D. Clinger's paper "How to Read Floating
+ * Point Numbers Accurately" [Proc. ACM SIGPLAN '90, pp. 92-101].
+ *
+ * Modifications:
+ *
+ *	1. We only require IEEE, IBM, or VAX double-precision
+ *		arithmetic (not IEEE double-extended).
+ *	2. We get by with floating-point arithmetic in a case that
+ *		Clinger missed -- when we're computing d * 10^n
+ *		for a small integer d and the integer n is not too
+ *		much larger than 22 (the maximum integer k for which
+ *		we can represent 10^k exactly), we may be able to
+ *		compute (d*10^k) * 10^(e-k) with just one roundoff.
+ *	3. Rather than a bit-at-a-time adjustment of the binary
+ *		result in the hard case, we use floating-point
+ *		arithmetic to determine the adjustment to within
+ *		one bit; only in really hard cases do we need to
+ *		compute a second residual.
+ *	4. Because of 3., we don't need a large table of powers of 10
+ *		for ten-to-e (just some small tables, e.g. of 10^k
+ *		for 0 <= k <= 22).
+ */

+/* dtoa for IEEE arithmetic (dmg): convert double to ASCII string.
+ *
+ * Inspired by "How to Print Floating-Point Numbers Accurately" by
+ * Guy L. Steele, Jr. and Jon L. White [Proc. ACM SIGPLAN '90, pp. 92-101].
+ *
+ * Modifications:
+ *	1. Rather than iterating, we use a simple numeric overestimate
+ *	   to determine k = floor(log10(d)).  We scale relevant
+ *	   quantities using O(log2(k)) rather than O(k) multiplications.
+ *	2. For some modes > 2 (corresponding to ecvt and fcvt), we don't
+ *	   try to generate digits strictly left to right.  Instead, we
+ *	   compute with fewer bits and propagate the carry if necessary
+ *	   when rounding the final digit up.  This is often faster.
+ *	3. Under the assumption that input will be rounded nearest,
+ *	   mode 0 renders 1e23 as 1e23 rather than 9.999999999999999e22.
+ *	   That is, we allow equality in stopping tests when the
+ *	   round-nearest rule will give the same floating-point value
+ *	   as would satisfaction of the stopping test with strict
+ *	   inequality.
+ *	4. We remove common factors of powers of 2 from relevant
+ *	   quantities.
+ *	5. When converting floating-point integers less than 1e16,
+ *	   we use floating-point arithmetic rather than resorting
+ *	   to multiple-precision integers.
+ *	6. When asked to produce fewer than 15 digits, we first try
+ *	   to get by with floating-point arithmetic; we resort to
+ *	   multiple-precision integer arithmetic only if we cannot
+ *	   guarantee that the floating-point calculation has given
+ *	   the correctly rounded result.  For k requested digits and
+ *	   "uniformly" distributed input, the probability is
+ *	   something like 10^(k-15) that we must resort to the Long
+ *	   calculation.

+.Sh NAME
+.Nm strtol, strtoq
+.Nd convert string value to a long or quad_t integer
+.Sh SYNOPSIS
+.Fd #include <stdlib.h>
+.Fd #include <limits.h>
+.Ft long
+.Fn strtol "char *nptr" "char **endptr" "int base"
+
+.Fd #include <sys/types.h>
+.Fd #include <stdlib.h>
+.Fd #include <limits.h>
+.Ft quad_t
+.Fn strtoq "char *nptr" "char **endptr" "int base"
+.Sh DESCRIPTION
+The
+.Fn strtol
+function
+converts the string in
+.Fa nptr
+to a
+.Em long
+value.
+The
+.Fn strtoq
+function
+converts the string in
+.Fa nptr
+to a
+.Em quad_t
+value.
+The conversion is done according to the given
+.Fa base ,
+which must be between 2 and 36 inclusive,
+or be the special value 0.
+.Pp
+The string may begin with an arbitrary amount of white space
+(as determined by
+.Xr isspace 3 )
+followed by a single optional
+.Ql +
+or
+.Ql -
+sign.
+If
+.Fa base
+is zero or 16,
+the string may then include a
+.Ql 0x
+prefix,
+and the number will be read in base 16; otherwise, a zero
+.Fa base
+is taken as 10 (decimal) unless the next character is
+.Ql 0 ,
+in which case it is taken as 8 (octal).
+.Pp
+The remainder of the string is converted to a
+.Em long
+value in the obvious manner,
+stopping at the first character which is not a valid digit
+in the given base.
+(In bases above 10, the letter
+.Ql A
+in either upper or lower case
+represents 10,
+.Ql B
+represents 11, and so forth, with
+.Ql Z
+representing 35.)
+.Pp
+If
+.Fa endptr
+is non nil,
+.Fn strtol
+stores the address of the first invalid character in
+.Fa *endptr .
+If there were no digits at all, however,
+.Fn strtol
+stores the original value of
+.Fa nptr
+in
+.Fa *endptr .
+(Thus, if
+.Fa *nptr
+is not
+.Ql \e0
+but
+.Fa **endptr
+is
+.Ql \e0
+on return, the entire string was valid.)
+.Sh RETURN VALUES
+The
+.Fn strtol
+function
+returns the result of the conversion,
+unless the value would underflow or overflow.
+If an underflow occurs,
+.Fn strtol
+returns
+.Dv LONG_MIN .
+If an overflow occurs,
+.Fn strtol
+returns
+.Dv LONG_MAX .
+In both cases,
+.Va errno
+is set to
+.Er ERANGE .
+.Sh ERRORS
+.Bl -tag -width Er
+.It Bq Er ERANGE
+The given string was out of range; the value converted has been clamped.
+.El
+.Sh SEE ALSO
+.Xr atof 3 ,
+.Xr atoi 3 ,
+.Xr atol 3 ,
+.Xr strtod 3 ,
+.Xr strtoul 3
+.Sh STANDARDS
+The
+.Fn strtol
+function
+conforms to
+.St -ansiC .
+.Sh BUGS
+Ignores the current locale.

+.Nm strtoul, strtouq
+.Nd convert a string to an unsigned long or uquad_t integer
+.Sh SYNOPSIS
+.Fd #include <stdlib.h>
+.Fd #include <limits.h>
+.Ft unsigned long
+.Fn strtoul "const char *nptr" "char **endptr" "int base"
+
+.Fd #include <sys/types.h>
+.Fd #include <stdlib.h>
+.Fd #include <limits.h>
+.Ft u_quad_t
+.Fn strtouq "const char *nptr" "char **endptr" "int base"
+.Sh DESCRIPTION
+The
+.Fn strtoul
+function
+converts the string in
+.Fa nptr
+to an
+.Em unsigned long
+value.
+The
+.Fn strtouq
+function
+converts the string in
+.Fa nptr
+to a
+.Em u_quad_t
+value.
+The conversion is done according to the given
+.Fa base ,
+which must be between 2 and 36 inclusive,
+or be the special value 0.
+.Pp
+The string may begin with an arbitrary amount of white space
+(as determined by
+.Xr isspace 3 )
+followed by a single optional
+.Ql +
+or
+.Ql -
+sign.
+If
+.Fa base
+is zero or 16,
+the string may then include a
+.Ql 0x
+prefix,
+and the number will be read in base 16; otherwise, a zero
+.Fa base
+is taken as 10 (decimal) unless the next character is
+.Ql 0 ,
+in which case it is taken as 8 (octal).
+.Pp
+The remainder of the string is converted to an
+.Em unsigned long
+value in the obvious manner,
+stopping at the end of the string
+or at the first character that does not produce a valid digit
+in the given base.
+(In bases above 10, the letter
+.Ql A
+in either upper or lower case
+represents 10,
+.Ql B
+represents 11, and so forth, with
+.Ql Z
+representing 35.)
+.Pp
+If
+.Fa endptr
+is non nil,
+.Fn strtoul
+stores the address of the first invalid character in
+.Fa *endptr .
+If there were no digits at all, however,
+.Fn strtoul
+stores the original value of
+.Fa nptr
+in
+.Fa *endptr .
+(Thus, if
+.Fa *nptr
+is not
+.Ql \e0
+but
+.Fa **endptr
+is
+.Ql \e0
+on return, the entire string was valid.)
+.Sh RETURN VALUES
+The
+.Fn strtoul
+function
+returns either the result of the conversion
+or, if there was a leading minus sign,
+the negation of the result of the conversion,
+unless the original (non-negated) value would overflow;
+in the latter case,
+.Fn strtoul
+returns
+.Dv ULONG_MAX
+and sets the global variable
+.Va errno
+to
+.Er ERANGE .
+.Sh ERRORS
+.Bl -tag -width Er
+.It Bq Er ERANGE
+The given string was out of range; the value converted has been clamped.
+.El
+.Sh SEE ALSO
+.Xr strtol 3
+.Sh STANDARDS
+The
+.Fn strtoul
+function

+.SH DESCRIPTION
+These routines implement an efficient mechanism to find an
+occurrence of a byte string within another byte string.
+.PP
+.I Bm_comp
+evaluates the
+.I patlen
+bytes starting at
+.IR pattern ,
+and returns a pointer to a structure describing them.
+The bytes referenced by
+.I pattern
+may be of any value.
+.PP
+The search takes advantage of the frequency distribution of the
+bytes in the text to be searched.
+If specified,
+.I freq
+should be an array of 256 values,
+with higher values indicating that the corresponding character occurs
+more frequently.
+(A less than optimal frequency distribution can only result in less
+than optimal performance, not incorrect results.)
+If
+.I freq
+is NULL,
+a system default table is used.
+.PP
+.I Bm_exec
+returns a pointer to the leftmost occurrence of the string given to
+.I bm_comp
+within
+.IR text ,
+or NULL if none occurs.
+The number of bytes in
+.I text
+must be specified by
+.IR len .
+.PP
+Space allocated for the returned description is discarded
+by calling
+.I bm_free
+with the returned description as an argument.
+.PP
+The asymptotic speed of
+.I bm_exec
+is
+.RI O( len / patlen ).

+function formats the information from
+.Fa timeptr
+into the buffer
+.Fa buf
+according to the string pointed to by
+.Fa format .
+.Pp
+The
+.Fa format
+string consists of zero or more conversion specifications and
+ordinary characters.
+All ordinary characters are copied directly into the buffer.
+A conversion specification consists of a percent sign
+.Ql %
+and one other character.
+.Pp
+No more than
+.Fa maxsize
+characters will be placed into the array.
+If the total number of resulting characters, including the terminating
+null character, is not more than
+.Fa maxsize ,
+.Fn strftime
+returns the number of characters in the array, not counting the
+terminating null.
+Otherwise, zero is returned.
+.Pp
+Each conversion specification is replaced by the characters as
+follows which are then copied into the buffer.

+.Os
+.Sh NAME
+.Nm strmode
+.Nd convert inode status information into a symbolic string
+.Sh SYNOPSIS
+.Fd #include <string.h>
+.Ft void
+.Fn strmode "mode_t mode" "char *bp"
+.Sh DESCRIPTION
+The
+.Fn strmode
+function
+converts a file
+.Fa mode
+(the type and permission information associated with an inode, see
+.Xr stat 2 )
+into a symbolic string which is stored in the location referenced by
+.Fa bp .
+This stored string is eleven characters in length plus a trailing
+.Dv NULL .
+.Pp
+The first character is the inode type, and will be one of the following:
+.Pp
+.Bl -tag -width flag -offset indent -compact
+.It \-
+regular file
+.It b
+block special
+.It c
+character special
+.It d
+directory
+.It l
+symbolic link
+.It p
+fifo
+.It s
+socket
+.It ?
+unknown inode type
+.El
+.Pp
+The next nine characters encode three sets of permissions, in three
+characters each.
+The first three characters are the permissions for the owner of the
+file, the second three for the group the file belongs to, and the
+third for the ``other'', or default, set of users.
+.Pp
+Permission checking is done as specifically as possible.
+If read permission is denied to the owner of a file in the first set
+of permissions, the owner of the file will not be able to read the file.
+This is true even if the owner is in the file's group and the group
+permissions allow reading or the ``other'' permissions allow reading.
+.Pp
+If the first character of the three character set is an ``r'', the file is
+readable for that set of users; if a dash ``\-'', it is not readable.
+.Pp
+If the second character of the three character set is a ``w'', the file is
+writable for that set of users; if a dash ``\-'', it is not writable.
+.Pp
+The third character is the first of the following characters that apply:
+.Bl -tag -width xxxx
+.It S
+If the character is part of the owner permissions and the file is not
+executable or the directory is not searchable, by the owner, and the
+set-user-id bit is set.
+.It S
+If the character is part of the group permissions and the file is not
+executable or the directory is not searchable, by the group, and the
+set-group-id bit is set.
+.It T
+If the character is part of the other permissions and the file is not
+executable or the directory is not searchable, by others, and the ``sticky''
+.Pq Dv S_ISVTX
+bit is set.
+.It s
+If the character is part of the owner permissions and the file is
+executable or the directory searchable, by the owner, and the set-user-id
+bit is set.
+.It s
+If the character is part of the group permissions and the file is
+executable or the directory searchable, by the group, and the set-group-id
+bit is set.
+.It t
+If the character is part of the other permissions and the file is
+executable or the directory searchable, by others, and the ``sticky''
+.Pq Dv S_ISVTX
+bit is set.
+.It x
+The file is executable or the directory is searchable.
+.It \-
+None of the above apply.
+.El
+.Pp
+The last character is a plus sign ``+'' if any there are any alternate
+or additional access control methods associated with the inode, otherwise
+it will be a space.
+.Sh RETURN VALUES
+The
+.Fn strmode
+function
+always returns 0.

+.Ft char *
+.Fn strtok "char *str" "const char *sep"
+.Sh DESCRIPTION
+.Bf -symbolic
+This interface is obsoleted by strsep(3).
+.Ef
+.Pp
+The
+.Fn strtok
+function
+is used to isolate sequential tokens in a null-terminated string,
+.Fa str .
+These tokens are separated in the string by at least one of the
+characters in
+.Fa sep .
+The first time that
+.Fn strtok
+is called,
+.Fa str
+should be specified; subsequent calls, wishing to obtain further tokens
+from the same string, should pass a null pointer instead.
+The separator string,
+.Fa sep ,
+must be supplied each time, and may change between calls.
+.Pp
+The
+.Fn strtok
+function
+returns a pointer to the beginning of each subsequent token in the string,
+after replacing the separator character itself with a
+.Dv NUL
+character.
+When no more tokens remain, a null pointer is returned.

+.Xr strstr 3
+.Sh STANDARDS
+The
+.Fn strtok
+function
+conforms to
+.St -ansiC .
+.Sh BUGS
+There is no way to get tokens from multiple strings simultaneously.
+.Pp
+The System V
+.Fn strtok ,
+if handed a string containing only delimiter characters,
+will not alter the next starting point, so that a call to
+.Fn strtok
+with a different (or empty) delimiter string
+may return a
+.Pf non- Dv NULL
+value.
+Since this implementation always alters the next starting point,
+such a sequence of calls would always return
+.Dv NULL .

+.Fn _exit "int status"
+.Sh DESCRIPTION
+The
+.Fn _exit
+function
+terminates a process with the following consequences:
+.Bl -bullet
+.It
+All of the descriptors open in the calling process are closed.
+This may entail delays, for example, waiting for output to drain;
+a process in this state may not be killed, as it is already dying.
+.It
+If the parent process of the calling process has an outstanding
+.Xr wait
+call
+or catches the
+.Dv SIGCHLD
+signal,
+it is notified of the calling process's termination and
+the
+.Em status
+is set as defined by
+.Xr wait 2 .
+.It
+The parent process-ID of all of the calling process's existing child
+processes are set to 1; the initialization process
+(see the DEFINITIONS section of
+.Xr intro 2 )
+inherits each of these processes.
+.It
+If the termination of the process causes any process group
+to become orphaned (usually because the parents of all members
+of the group have now exited; see
+.Dq orphaned process group
+in
+.Xr intro 2 ) ,
+and if any member of the orphaned group is stopped,
+the
+.Dv SIGHUP
+signal and the
+.Dv SIGCONT
+signal are sent to all members of the newly-orphaned process group.
+.It
+If the process is a controlling process (see
+.Xr intro 2 ) ,
+the
+.Dv SIGHUP
+signal is sent to the foreground process group of the controlling terminal,
+and all current access to the controlling terminal is revoked.

+.Os BSD 4.2
+.Sh NAME
+.Nm accept
+.Nd accept a connection on a socket
+.Sh SYNOPSIS
+.Fd #include <sys/types.h>
+.Fd #include <sys/socket.h>
+.Ft int
+.Fn accept "int s" "struct sockaddr *addr" "int *addrlen"
+.Sh DESCRIPTION
+The argument
+.Fa s
+is a socket that has been created with
+.Xr socket 2 ,
+bound to an address with
+.Xr bind 2 ,
+and is listening for connections after a
+.Xr listen 2 .
+The
+.Fn accept
+argument
+extracts the first connection request
+on the queue of pending connections, creates
+a new socket with the same properties of 
+.Fa s
+and allocates a new file descriptor
+for the socket.  If no pending connections are
+present on the queue, and the socket is not marked
+as non-blocking,
+.Fn accept
+blocks the caller until a connection is present.
+If the socket is marked non-blocking and no pending
+connections are present on the queue, 
+.Fn accept
+returns an error as described below.
+The accepted socket
+may not be used
+to accept more connections.  The original socket
+.Fa s
+remains open.
+.Pp
+The argument
+.Fa addr
+is a result parameter that is filled in with
+the address of the connecting entity,
+as known to the communications layer.
+The exact format of the
+.Fa addr
+parameter is determined by the domain in which the communication
+is occurring.
+The 
+.Fa addrlen
+is a value-result parameter; it should initially contain the
+amount of space pointed to by
+.Fa addr ;
+on return it will contain the actual length (in bytes) of the
+address returned.
+This call
+is used with connection-based socket types, currently with
+.Dv SOCK_STREAM . 
+.Pp
+It is possible to
+.Xr select 2
+a socket for the purposes of doing an
+.Fn accept
+by selecting it for read.
+.Pp
+For certain protocols which require an explicit confirmation,
+such as
+.Tn ISO
+or
+.Tn DATAKIT ,
+.Fn accept
+can be thought of
+as merely dequeuing the next connection
+request and not implying confirmation.
+Confirmation can be implied by a normal read or write on the new
+file descriptor, and rejection can be implied by closing the
+new socket.
+.Pp
+One can obtain user connection request data without confirming
+the connection by issuing a 
+.Xr recvmsg 2
+call with an
+.Fa msg_iovlen
+of 0 and a non-zero
+.Fa msg_controllen ,
+or by issuing a
+.Xr getsockopt 2
+request.
+Similarly, one can provide user connection rejection information
+by issuing a
+.Xr sendmsg 2
+call with providing only the control information,
+or by calling
+.Xr setsockopt 2 .
+.Sh RETURN VALUES
+The call returns \-1 on error.  If it succeeds, it returns a non-negative
+integer that is a descriptor for the accepted socket.
+.Sh ERRORS
+The
+.Fn accept
+will fail if:
+.Bl -tag -width Er
+.It Bq Er EBADF
+The descriptor is invalid.
+.It Bq Er ENOTSOCK
+The descriptor references a file, not a socket.
+.It Bq Er EOPNOTSUPP
+The referenced socket is not of type
+.Dv SOCK_STREAM . 
+.It Bq Er EFAULT
+The
+.Fa addr
+parameter is not in a writable part of the
+user address space.
+.It Bq Er EWOULDBLOCK
+The socket is marked non-blocking and no connections
+are present to be accepted.

+.Fn access "const char *path" "int mode"
+.Sh DESCRIPTION
+The
+.Fn access
+function checks the accessibility of the
+file named by
+.Fa path
+for the access permissions indicated by
+.Fa mode .
+The value of
+.Fa mode
+is the bitwise inclusive OR of the access permissions to be
+checked
+.Pf ( Dv R_OK
+for read permission,
+.Dv W_OK
+for write permission and
+.Dv X_OK
+for execute/search permission) or the existence test,
+.Dv F_OK .
+All components of the pathname
+.Fa path
+are checked for access permissions (including
+.Dv F_OK ) .
+.Pp
+The real user ID is used in place of the effective user ID
+and the real group access list
+(including the real group ID) are
+used in place of the effective ID for verifying permission.
+.Pp
+Even if a process has appropriate privileges and indicates success for
+.Dv X_OK ,
+the file may not actually have execute permission bits set.
+Likewise for
+.Dv R_OK
+and
+.Dv W_OK .
+.Sh RETURN VALUES
+If
+.Fa path
+cannot be found or if any of the desired access modes would
+not be granted, then a -1 value is returned; otherwise
+a 0 value is returned.

+The

+function
+sets the break or lowest address
+of a process's data segment (uninitialized data) to
+.Fa addr
+(immediately above bss).
+Data addressing is restricted between
+.Fa addr
+and the lowest stack pointer to the stack segment.
+Memory is allocated by

+in page size pieces;
+if
+.Fa addr
+is not evenly divisible by the system page size, it is

+.Sh DESCRIPTION
+The function
+.Fn chmod
+sets the file permission bits
+of the file
+specified by the pathname
+.Fa path
+to
+.Fa mode .
+.Fn Fchmod
+sets the permission bits of the specified
+file descriptor
+.Fa fd .
+.Fn Chmod
+verifies that the process owner (user) either owns
+the file specified by
+.Fa path
+(or
+.Fa fd ) ,
+or
+is the super-user.
+A mode is created from
+.Em or'd
+permission bit masks
+defined in
+.Aq Pa sys/stat.h :
+.Bd -literal -offset indent -compact
+#define S_IRWXU 0000700    /* RWX mask for owner */

+#define S_ISVTX 0001000    /* save swapped text even after use */
+.Ed
+.Pp
+The
+.Dv ISVTX
+(the
+.Em sticky bit )
+indicates to the system which executable files are shareable (the
+default) and the system maintains the program text of the files
+in the swap area. The sticky bit may only be set by the super user
+on shareable executable files.
+.Pp
+If mode
+.Dv ISVTX
+(the `sticky bit') is set on a directory,
+an unprivileged user may not delete or rename
+files of other users in that directory. The sticky bit may be
+set by any user on a directory which the user owns or has appropriate
+permissions.
+For more details of the properties of the sticky bit, see
+.Xr sticky 8 .
+.Pp
+Writing or changing the owner of a file
+turns off the set-user-id and set-group-id bits
+unless the user is the super-user.
+This makes the system somewhat more secure
+by protecting set-user-id (set-group-id) files
+from remaining set-user-id (set-group-id) if they are modified,
+at the expense of a degree of compatibility.
+.Sh RETURN VALUES
+Upon successful completion, a value of 0 is returned.
+Otherwise, a value of -1 is returned and
+.Va errno
+is set to indicate the error.
+.Sh ERRORS

+.Sh DESCRIPTION
+The
+.Fn close
+call deletes a descriptor from the per-process object
+reference table.
+If this is the last reference to the underlying object, the
+object will be deactivated.
+For example, on the last close of a file
+the current
+.Em seek
+pointer associated with the file is lost;
+on the last close of a
+.Xr socket 2
+associated naming information and queued data are discarded;
+on the last close of a file holding an advisory lock
+the lock is released (see further
+.Xr flock 2 ) .
+.Pp
+When a process exits,
+all associated file descriptors are freed, but since there is
+a limit on active descriptors per processes, the
+.Fn close
+function call
+is useful when a large quantity of file descriptors are being handled.
+.Pp
+When a process forks (see
+.Xr fork 2 ) ,
+all descriptors for the new child process reference the same
+objects as they did in the parent before the fork.
+If a new process is then to be run using
+.Xr execve 2 ,
+the process would normally inherit these descriptors.  Most
+of the descriptors can be rearranged with
+.Xr dup2 2
+or deleted with
+.Fn close
+before the
+.Xr execve
+is attempted, but if some of these descriptors will still
+be needed if the execve fails, it is necessary to arrange for them
+to be closed if the execve succeeds.
+For this reason, the call
+.Dq Li fcntl(d, F_SETFD, 1)
+is provided,
+which arranges that a descriptor will be closed after a successful
+execve; the call
+.Dq Li fcntl(d, F_SETFD, 0)
+restores the default,
+which is to not close the descriptor.
+.Sh RETURN VALUES
+Upon successful completion, a value of 0 is returned.
+Otherwise, a value of -1 is returned and the global integer variable
+.Va errno
+is set to indicate the error.
+.Sh ERRORS
+.Fn Close
+will fail if:
+.Bl -tag -width Er
+.It Bq Er EBADF
+.Fa D
+is not an active descriptor.
+.It Bq Er EINTR
+An interrupt was received.

+.Nd execute a file
+.Sh SYNOPSIS
+.Fd #include <unistd.h>
+.Ft int
+.Fn execve "const char *path" "char *const argv[]" "char *const envp[]"
+.Sh DESCRIPTION
+.Fn Execve
+transforms the calling process into a new process.
+The new process is constructed from an ordinary file,
+whose name is pointed to by
+.Fa path ,
+called the
+.Em new process file .
+This file is either an executable object file,
+or a file of data for an interpreter.
+An executable object file consists of an identifying header,
+followed by pages of data representing the initial program (text)
+and initialized data pages.  Additional pages may be specified
+by the header to be initialized with zero data;  see
+.Xr a.out 5 .
+.Pp
+An interpreter file begins with a line of the form:
+.Pp
+.Bd -filled -offset indent -compact
+.Sy \&#!
+.Em interpreter
+.Bq Em arg
+.Ed
+.Pp
+When an interpreter file is
+.Fn execve Ap d ,
+the system
+.Fn execve Ap s
+runs the specified
+.Em interpreter .
+If the optional
+.Em arg
+is specified, it becomes the first argument to the
+.Em interpreter ,
+and the name of the originally
+.Fn execve Ap d
+file becomes the second argument;
+otherwise, the name of the originally
+.Fn execve Ap d
+file becomes the first argument.  The original arguments are shifted over to
+become the subsequent arguments.  The zeroth argument, normally the name of the
+.Fn execve Ap d
+file, is left unchanged.
+.Pp
+The argument
+.Fa argv
+is a pointer to a null-terminated array of
+character pointers to null-terminated character strings.
+These strings construct the argument list to be made available to the new
+process.  At least one argument must be present in
+the array; by custom, the first element should be
+the name of the executed program (for example, the last component of
+.Fa path ) .
+.Pp
+The argument
+.Fa envp
+is also a pointer to a null-terminated array of
+character pointers to null-terminated strings.
+A pointer to this array is normally stored in the global variable
+.Va environ.
+These strings pass information to the
+new process that is not directly an argument to the command (see
+.Xr environ 7 ) .
+.Pp
+File descriptors open in the calling process image remain open in
+the new process image, except for those for which the close-on-exec
+flag is set (see
+.Xr close 2
+and
+.Xr fcntl 2 ) .
+Descriptors that remain open are unaffected by
+.Fn execve .
+.Pp
+Signals set to be ignored in the calling process are set to be ignored in
+the
+new process. Signals which are set to be caught in the calling process image
+are set to default action in the new process image.
+Blocked signals remain blocked regardless of changes to the signal action.
+The signal stack is reset to be undefined (see
+.Xr sigaction 2
+for more information).
+.Pp
+If the set-user-ID mode bit of the new process image file is set
+(see
+.Xr chmod 2 ) ,
+the effective user ID of the new process image is set to the owner ID
+of the new process image file.
+If the set-group-ID mode bit of the new process image file is set,
+the effective group ID of the new process image is set to the group ID
+of the new process image file.
+(The effective group ID is the first element of the group list.)
+The real user ID, real group ID and
+other group IDs of the new process image remain the same as the calling
+process image.
+After any set-user-ID and set-group-ID processing,
+the effective user ID is recorded as the saved set-user-ID,
+and the effective group ID is recorded as the saved set-group-ID.
+These values may be used in changing the effective IDs later (see
+.Xr setuid 2 ) .
+.Pp
+The new process also inherits the following attributes from
+the calling process:
+.Pp
+.Bl -column parent_process_ID -offset indent -compact
+.It process ID Ta see Xr getpid 2
+.It parent process ID Ta see Xr getppid 2
+.It process group ID Ta see Xr getpgrp 2

+.It resource limits Ta see Xr getrlimit 2
+.It file mode mask Ta see Xr umask 2
+.It signal mask Ta see Xr sigaction 2 ,
+.Xr sigsetmask 2
+.El
+.Pp
+When a program is executed as a result of an
+.Fn execve
+call, it is entered as follows:
+.Bd -literal -offset indent
+main(argc, argv, envp)
+int argc;
+char **argv, **envp;
+.Ed
+.Pp
+where
+.Fa argc
+is the number of elements in
+.Fa argv
+(the ``arg count'')
+and
+.Fa argv
+points to the array of character pointers
+to the arguments themselves.
+.Sh RETURN VALUES
+As the
+.Fn execve
+function overlays the current process image 
+with a new process image the successful call
+has no process to return to.
+If
+.Fn execve
+does return to the calling process an error has occurred; the

+.It Dv F_SETOWN
+Set the process or process group
+to receive
+.Dv SIGIO
+and
+.Dv SIGURG
+signals;

+.Fa arg
+is interpreted as a process ID.
+.El
+.Pp
+The flags for the
+.Dv F_GETFL
+and
+.Dv F_SETFL
+flags are as follows:
+.Bl -tag -width O_NONBLOCKX
+.It Dv O_NONBLOCK
+Non-blocking I/O; if no data is available to a
+.Xr read
+call, or if a
+.Xr write
+operation would block,
+the read or write call returns -1 with the error
+.Er EAGAIN .
+.It Dv O_APPEND
+Force each write to append at the end of file;
+corresponds to the
+.Dv O_APPEND
+flag of
+.Xr open 2 .
+.It Dv O_ASYNC
+Enable the
+.Dv SIGIO
+signal to be sent to the process group
+when I/O is possible, e.g.,
+upon availability of data to be read.
+.El
+.Pp
+Several commands are available for doing advisory file locking;
+they all operate on the following structure:
+.ne 7v
+.Bd -literal
+struct flock {
+	off_t	l_start;	/* starting offset */
+	off_t	l_len;		/* len = 0 means until end of file */
+	pid_t	l_pid;		/* lock owner */
+	short	l_type;		/* lock type: read/write, etc. */
+	short	l_whence;	/* type of l_start */
+};
+.Ed
+The commands available for advisory record locking are as follows:
+.Bl -tag -width F_SETLKWX
+.It Dv F_GETLK
+Get the first lock that blocks the lock description pointed to by the
+third argument,
+.Fa arg ,
+taken as a pointer to a
+.Fa "struct flock"
+(see above).
+The information retrieved overwrites the information passed to
+.Nm fcntl
+in the
+.Fa flock
+structure.
+If no lock is found that would prevent this lock from being created,
+the structure is left unchanged by this function call except for the
+lock type which is set to
+.Dv F_UNLCK .
+.It Dv F_SETLK
+Set or clear a file segment lock according to the lock description
+pointed to by the third argument,
+.Fa arg ,
+taken as a pointer to a
+.Fa "struct flock"
+(see above).
+.Dv F_SETLK
+is used to establish shared (or read) locks
+.Dv (F_RDLCK)
+or exclusive (or write) locks,
+.Dv (F_WRLCK) ,
+as well as remove either type of lock
+.Dv (F_UNLCK) .
+If a shared or exclusive lock cannot be set,
+.Nm fcntl
+returns immediately with
+.Er EACCES .
+.It Dv F_SETLKW
+This command is the same as
+.Dv F_SETLK
+except that if a shared or exclusive lock is blocked by other locks,
+the process waits until the request can be satisfied.
+If a signal that is to be caught is received while
+.Nm fcntl
+is waiting for a region, the
+.Nm fcntl
+will be interrupted if the signal handler has not specified the
+.Dv SA_RESTART
+(see
+.Xr sigaction 2 ) .
+.El
+.Pp
+When a shared lock has been set on a segment of a file,
+other processes can set shared locks on that segment
+or a portion of it.
+A shared lock prevents any other process from setting an exclusive
+lock on any portion of the protected area.
+A request for a shared lock fails if the file descriptor was not
+opened with read access.
+.Pp
+An exclusive lock prevents any other process from setting a shared lock or
+an exclusive lock on any portion of the protected area.
+A request for an exclusive lock fails if the file was not
+opened with write access.
+.Pp
+The value of
+.Fa l_whence
+is
+.Dv SEEK_SET ,
+.Dv SEEK_CUR ,
+or
+.Dv SEEK_END
+to indicate that the relative offset,
+.Fa l_start
+bytes, will be measured from the start of the file,
+current position, or end of the file, respectively.
+The value of
+.Fa l_len
+is the number of consecutive bytes to be locked.
+If
+.Fa l_len
+is negative, the result is undefined.
+The
+.Fa l_pid
+field is only used with
+.Dv F_GETLK
+to return the process ID of the process holding a blocking lock.
+After a successful
+.Dv F_GETLK
+request, the value of
+.Fa l_whence
+is
+.Dv SEEK_SET .
+.Pp
+Locks may start and extend beyond the current end of a file,
+but may not start or extend before the beginning of the file.
+A lock is set to extend to the largest possible value of the
+file offset for that file if
+.Fa l_len
+is set to zero. If
+.Fa l_whence
+and
+.Fa l_start
+point to the beginning of the file, and
+.Fa l_len
+is zero, the entire file is locked.
+If an application wishes only to do entire file locking, the
+.Xr flock 2
+system call is much more efficient.
+.Pp
+There is at most one type of lock set for each byte in the file.
+Before a successful return from an
+.Dv F_SETLK
+or an
+.Dv F_SETLKW
+request when the calling process has previously existing locks
+on bytes in the region specified by the request,
+the previous lock type for each byte in the specified
+region is replaced by the new lock type.
+As specified above under the descriptions
+of shared locks and exclusive locks, an
+.Dv F_SETLK
+or an
+.Dv F_SETLKW
+request fails or blocks respectively when another process has existing
+locks on bytes in the specified region and the type of any of those
+locks conflicts with the type specified in the request.
+.Pp
+This interface follows the completely stupid semantics of System V and
+.St -p1003.1-88
+that require that all locks associated with a file for a given process are
+removed when \fIany\fP file descriptor for that file is closed by that process.
+This semantic means that applications must be aware of any files that
+a subroutine library may access.
+For example if an application for updating the password file locks the
+password file database while making the update, and then calls
+.Xr getpwname 3
+to retrieve a record,
+the lock will be lost because 
+.Xr getpwname 3
+opens, reads, and closes the password database.
+The database close will release all locks that the process has
+associated with the database, even if the library routine never
+requested a lock on the database.
+Another minor semantic problem with this interface is that
+locks are not inherited by a child process created using the
+.Xr fork 2
+function.
+The
+.Xr flock 2
+interface has much more rational last close semantics and
+allows locks to be inherited by child processes.
+.Xr Flock 2
+is recommended for applications that want to ensure the integrity
+of their locks when using library routines or wish to pass locks
+to their children.
+Note that 
+.Xr flock 2
+and 
+.Xr fcntl 2
+locks may be safely used concurrently.
+.Pp
+All locks associated with a file for a given process are
+removed when the process terminates.
+.Pp
+A potential for deadlock occurs if a process controlling a locked region
+is put to sleep by attempting to lock the locked region of another process.
+This implementation detects that sleeping until a locked region is unlocked
+would cause a deadlock and fails with an
+.Er EDEADLK
+error.
+.Sh RETURN VALUES
+Upon successful completion, the value returned depends on
+.Fa cmd
+as follows:
+.Bl -tag -width F_GETOWNX -offset indent
+.It Dv F_DUPFD
+A new file descriptor.
+.It Dv F_GETFD

+.It Dv F_GETFL

+.Sh NAME
+.Nm flock
+.Nd "apply or remove an advisory lock on an open file"
+.Sh SYNOPSIS
+.Fd #include <sys/file.h>
+.Fd #define	LOCK_SH	1	/* shared lock */
+.Fd #define	LOCK_EX	2	/* exclusive lock */
+.Fd #define	LOCK_NB	4	/* don't block when locking */
+.Fd #define	LOCK_UN	8	/* unlock */
+.Ft int
+.Fn flock "int fd" "int operation"
+.Sh DESCRIPTION
+.Fn Flock
+applies or removes an
+.Em advisory
+lock on the file associated with the file descriptor
+.Fa fd .
+A lock is applied by specifying an
+.Fa operation
+parameter that is one of
+.Dv LOCK_SH
+or
+.Dv LOCK_EX
+with the optional addition of
+.Dv LOCK_NB .
+To unlock
+an existing lock
+.Dv operation
+should be
+.Dv LOCK_UN .
+.Pp
+Advisory locks allow cooperating processes to perform
+consistent operations on files, but do not guarantee
+consistency (i.e., processes may still access files
+without using advisory locks possibly resulting in
+inconsistencies).
+.Pp
+The locking mechanism allows two types of locks:
+.Em shared
+locks and
+.Em exclusive
+locks.
+At any time multiple shared locks may be applied to a file,
+but at no time are multiple exclusive, or both shared and exclusive,
+locks allowed simultaneously on a file.  
+.Pp
+A shared lock may be
+.Em upgraded
+to an exclusive lock, and vice versa, simply by specifying
+the appropriate lock type; this results in the previous
+lock being released and the new lock applied (possibly
+after other processes have gained and released the lock).
+.Pp
+Requesting a lock on an object that is already locked
+normally causes the caller to be blocked until the lock may be
+acquired.  If
+.Dv LOCK_NB
+is included in
+.Fa operation ,
+then this will not happen; instead the call will fail and
+the error
+.Er EWOULDBLOCK
+will be returned.
+.Sh NOTES
+Locks are on files, not file descriptors.  That is, file descriptors
+duplicated through
+.Xr dup 2
+or
+.Xr fork 2
+do not result in multiple instances of a lock, but rather multiple
+references to a single lock.  If a process holding a lock on a file
+forks and the child explicitly unlocks the file, the parent will
+lose its lock.
+.Pp
+Processes blocked awaiting a lock may be awakened by signals.
+.Sh RETURN VALUES
+Zero is returned if the operation was successful;
+on an error a -1 is returned and an error code is left in
+the global location
+.Va errno .
+.Sh ERRORS
+The
+.Fn flock
+call fails if:
+.Bl -tag -width Er
+.It Bq Er EWOULDBLOCK
+The file is locked and the
+.Dv LOCK_NB
+option was specified.
+.It Bq Er EBADF
+The argument
+.Fa fd
+is an invalid descriptor.
+.It Bq Er EINVAL
+The argument
+.Fa fd
+refers to an object other than a file.

+.Sh SYNOPSIS
+.Fd #include <sys/dirent.h>
+.Ft int
+.Fn getdirentries "int fd" "char *buf" "int nbytes" "long *basep"
+.Sh DESCRIPTION
+.Fn Getdirentries
+reads directory entries from the directory
+referenced by the file descriptor
+.Fa fd
+into the buffer pointed to by
+.Fa buf ,
+in a filesystem independent format.
+Up to
+.Fa nbytes
+of data will be transferred.
+.Fa Nbytes
+must be greater than or equal to the
+block size associated with the file,
+see
+.Xr stat 2 .
+Some filesystems may not support
+.Fn getdirentries
+with buffers smaller than this size.
+.Pp
+The data in the buffer is a series of
+.Em dirent
+structures each containing the following entries:
+.Bd -literal -offset indent
+unsigned long	d_fileno;
+unsigned short	d_reclen;
+unsigned short	d_namlen;
+char    	d_name[MAXNAMELEN + 1]; /* see below */
+.Ed
+.Pp
+The
+.Fa d_fileno
+entry is a number which is unique for each
+distinct file in the filesystem.
+Files that are linked by hard links (see
+.Xr link 2 )
+have the same
+.Fa d_fileno .
+The
+.Fa d_reclen
+entry is the length, in bytes, of the directory record.
+The
+.Fa d_name
+entry contains a null terminated file name.
+The
+.Fa d_namlen
+entry specifies the length of the file name excluding the null byte.
+Thus the actual size of
+.Fa d_name
+may vary from 1 to
+.Dv MAXNAMELEN
+\&+ 1.
+.Pp
+Entries may be separated by extra space.
+The
+.Fa d_reclen
+entry may be used as an offset from the start of a
+.Fa dirent
+structure to the next structure, if any.
+.Pp
+The actual number of bytes transferred is returned.
+The current position pointer associated with
+.Fa fd
+is set to point to the next block of entries.
+The pointer may not advance by the number of bytes returned by
+.Fn getdirentries .
+A value of zero is returned when
+the end of the directory has been reached.
+.Pp
+.Fn Getdirentries
+writes the position of the block read into the location pointed to by
+.Fa basep .
+Alternatively, the current position pointer may be set and retrieved by
+.Xr lseek 2 .
+The current position pointer should only be set to a value returned by
+.Xr lseek 2 ,
+a value returned in the location pointed to by
+.Fa basep ,
+or zero.
+.Sh RETURN VALUES
+If successful, the number of bytes actually transferred is returned.
+Otherwise, -1 is returned and the global variable
+.Va errno
+is set to indicate the error.
+.Sh ERRORS
+.Fn Getdirentries
+will fail if:
+.Bl -tag -width Er
+.It Bq Er EBADF
+.Fa fd
+is not a valid file descriptor open for reading.

+.Fd #include <unistd.h>
+.Ft char *
+.Fn getlogin void
+.Ft int
+.Fn setlogin "const char *name"
+.Sh DESCRIPTION
+The
+.Fn getlogin
+routine
+returns the login name of the user associated with the current session,
+as previously set by
+.Fn setlogin .
+The name is normally associated with a login shell
+at the time a session is created,
+and is inherited by all processes descended from the login shell.
+(This is true even if some of those processes assume another user ID,
+for example when
+.Xr su 1
+is used.)
+.Pp
+.Fn Setlogin
+sets the login name of the user associated with the current session to
+.Fa name .
+This call is restricted to the super-user, and
+is normally used only when a new session is being created on behalf
+of the named user
+(for example, at login time, or when a remote shell is invoked).
+.Sh RETURN VALUES
+If a call to
+.Fn getlogin
+succeeds, it returns a pointer to a null-terminated string in a static buffer.
+If the name has not been set, it returns
+.Dv NULL .
+If a call to
+.Fn setlogin
+succeeds, a value of 0 is returned.  If
+.Fn setlogin
+fails, a value of -1 is returned and an error code is
+placed in the global location
+.Va errno .
+.Sh ERRORS
+The following errors may be returned by these calls:
+.Bl -tag -width Er
+.It Bq Er EFAULT
+The
+.Fa name
+parameter gave an
+invalid address.
+.It Bq Er EINVAL
+The
+.Fa name
+parameter
+pointed to a string that was too long.
+Login names are limited to
+.Dv MAXLOGNAME
+(from
+.Ao Pa sys/param.h Ac )
+characters, currently 12.
+.It Bq Er EPERM
+The caller tried to set the login name and was not the super-user.
+.El
+.Sh SEE ALSO
+.Xr setsid 2
+.Sh BUGS
+Login names are limited in length by
+.Fn setlogin .
+However, lower limits are placed on login names elsewhere in the system
+.Pf ( Dv UT_NAMESIZE
+in
+.Ao Pa utmp.h Ac ) .
+.Pp
+In earlier versions of the system,
+.Fn getlogin
+failed unless the process was associated with a login terminal.
+The current implementation (using
+.Fn setlogin )
+allows getlogin to succeed even when the process has no controlling terminal.
+In earlier versions of the system, the value returned by
+.Fn getlogin
+could not be trusted without checking the user ID.
+Portable programs should probably still make this check.
+.Sh HISTORY
+The
+.Fn getlogin
+function first appeared in 4.4BSD.

+.Sh DESCRIPTION
+The process group of the current process is returned by
+.Fn getpgrp .
+.Pp
+Process groups are used for distribution of signals, and
+by terminals to arbitrate requests for their input: processes
+that have the same process group as the terminal are foreground
+and may read, while others will block with a signal if they attempt
+to read.
+.Pp
+This call is thus used by programs such as
+.Xr csh 1
+to create

+in implementing job control.
+The

+.Sh COMPATIBILITY
+This version of
+.Fn getpgrp
+differs from past Berkeley versions by not taking a

+argument.
+This incompatibility is required by
+.St -p1003.1-88 .
+.Pp
+From the
+.St -p1003.1-88
+Rationale:
+.sp
+4.3BSD provides a
+.Fn getpgrp
+function that returns the process group ID for a specified process.
+Although this function is used to support job control, all known
+job-control shells always specify the calling process with this
+function.
+Thus, the simpler System V
+.Fn getpgrp
+suffices, and the added complexity of the 4.3BSD
+.Fn getpgrp
+has been omitted from POSIX.1.

+.Xr sbrk 2
+system call.
+.It Li RLIMIT_FSIZE
+The largest size (in bytes) file that may be created.
+.It Li RLIMIT_MEMLOCK
+The maximum size (in bytes) which a process may lock into memory
+using the
+.Xr mlock 2
+function.
+.It Li RLIMIT_NOFILE
+The maximum number of open files for this process.
+.It Li RLIMIT_NPROC
+The maximum number of simultaneous processes for this user id.
+.It Li RLIMIT_RSS
+The maximum size (in bytes) to which a process's resident set size may
+grow.
+This imposes a limit on the amount of physical memory to be given to
+a process; if memory is tight, the system will prefer to take memory
+from processes that are exceeding their declared resident set size.
+.It Li RLIMIT_STACK
+The maximum size (in bytes) of the stack segment for a process;
+this defines how far a program's stack segment may be extended.
+Stack extension is performed automatically by the system.
+.El
+.Pp
+A resource limit is specified as a soft limit and a hard limit.  When a
+soft limit is exceeded a process may receive a signal (for example, if
+the cpu time or file size is exceeded), but it will be allowed to
+continue execution until it reaches the hard limit (or modifies
+its resource limit).  The 
+.Em rlimit
+structure is used to specify the hard and soft limits on a resource,
+.Bd -literal -offset indent
+struct rlimit {
+	rlim_t	rlim_cur;	/* current (soft) limit */
+	rlim_t	rlim_max;	/* hard limit */
+};
+.Ed
+.Pp
+Only the super-user may raise the maximum limits.  Other users
+may only alter 
+.Fa rlim_cur
+within the range from 0 to 
+.Fa rlim_max
+or (irreversibly) lower
+.Fa rlim_max .
+.Pp
+An
+.Dq infinite
+value for a limit is defined as
+.Dv RLIM_INFINITY .
+.Pp
+Because this information is stored in the per-process information,
+this system call must be executed directly by the shell if it
+is to affect all future processes created by the shell;
+.Ic limit
+is thus a built-in command to
+.Xr csh 1 .
+.Pp
+The system refuses to extend the data or stack space when the limits
+would be exceeded in the normal way: a
+.Xr break
+call fails if the data space limit is reached.
+When the stack limit is reached, the process receives
+a segmentation fault
+.Pq Dv SIGSEGV ;
+if this signal is not
+caught by a handler using the signal stack, this signal
+will kill the process.
+.Pp
+A file I/O operation that would create a file larger that the process'
+soft limit will cause the write to fail and a signal
+.Dv SIGXFSZ
+to be
+generated; this normally terminates the process, but may be caught.  When
+the soft cpu time limit is exceeded, a signal
+.Dv SIGXCPU
+is sent to the
+offending process.
+.Sh RETURN VALUES
+A 0 return value indicates that the call succeeded, changing
+or returning the resource limit.   A return value of -1 indicates
+that an error occurred, and an error code is stored in the global
+location
+.Va errno .
+.Sh ERRORS

+.Ft int
+.Fn setsockopt "int s" "int level" "int optname" "const void *optval" "int optlen"
+.Sh DESCRIPTION
+.Fn Getsockopt
+and
+.Fn setsockopt
+manipulate the
+.Em options
+associated with a socket.  Options may exist at multiple
+protocol levels; they are always present at the uppermost
+.Dq socket
+level.
+.Pp
+When manipulating socket options the level at which the
+option resides and the name of the option must be specified.
+To manipulate options at the socket level,
+.Fa level
+is specified as
+.Dv SOL_SOCKET .
+To manipulate options at any
+other level the protocol number of the appropriate protocol
+controlling the option is supplied.  For example,
+to indicate that an option is to be interpreted by the
+.Tn TCP
+protocol,
+.Fa level
+should be set to the protocol number of
+.Tn TCP ;
+see
+.Xr getprotoent 3 .
+.Pp
+The parameters
+.Fa optval
+and
+.Fa optlen
+are used to access option values for
+.Fn setsockopt .
+For
+.Fn getsockopt
+they identify a buffer in which the value for the
+requested option(s) are to be returned.  For
+.Fn getsockopt ,
+.Fa optlen
+is a value-result parameter, initially containing the
+size of the buffer pointed to by
+.Fa optval ,
+and modified on return to indicate the actual size of
+the value returned.  If no option value is
+to be supplied or returned,
+.Fa optval
+may be NULL.
+.Pp
+.Fa Optname
+and any specified options are passed uninterpreted to the appropriate
+protocol module for interpretation.
+The include file
+.Ao Pa sys/socket.h Ac
+contains definitions for
+socket level options, described below.
+Options at other protocol levels vary in format and
+name; consult the appropriate entries in
+section
+4 of the manual.
+.Pp
+Most socket-level options utilize an
+.Fa int
+parameter for
+.Fa optval .
+For
+.Fn setsockopt ,
+the parameter should be non-zero to enable a boolean option,
+or zero if the option is to be disabled.
+.Dv SO_LINGER
+uses a
+.Fa struct linger
+parameter, defined in
+.Ao Pa sys/socket.h Ac ,
+which specifies the desired state of the option and the
+linger interval (see below).
+.Dv SO_SNDTIMEO
+and
+.Dv SO_RCVTIMEO
+use a
+.Fa struct timeval
+parameter, defined in
+.Ao Pa sys/time.h Ac .
+.Pp
+The following options are recognized at the socket level.
+Except as noted, each may be examined with
+.Fn getsockopt
+and set with
+.Fn setsockopt .
+.Bl -column SO_OOBINLINE -offset indent

+.It Dv SO_TYPE Ta "get the type of the socket (get only)"
+.It Dv SO_ERROR Ta "get and clear error on the socket (get only)"
+.El
+.Pp
+.Dv SO_DEBUG
+enables debugging in the underlying protocol modules.
+.Dv SO_REUSEADDR
+indicates that the rules used in validating addresses supplied
+in a
+.Xr bind 2
+call should allow reuse of local addresses.
+.Dv SO_REUSEPORT
+allows completely duplicate bindings by multiple processes
+if they all set
+.Dv SO_REUSEPORT
+before binding the port.
+This option permits multiple instances of a program to each
+receive UDP/IP multicast or broadcast datagrams destined for the bound port.
+.Dv SO_KEEPALIVE
+enables the
+periodic transmission of messages on a connected socket.  Should the
+connected party fail to respond to these messages, the connection is
+considered broken and processes using the socket are notified via a
+.Dv SIGPIPE
+signal when attempting to send data.
+.Dv SO_DONTROUTE
+indicates that outgoing messages should
+bypass the standard routing facilities.  Instead, messages are directed
+to the appropriate network interface according to the network portion
+of the destination address.
+.Pp
+.Dv SO_LINGER
+controls the action taken when unsent messages
+are queued on socket and a 
+.Xr close 2
+is performed.
+If the socket promises reliable delivery of data and
+.Dv SO_LINGER is set,
+the system will block the process on the 
+.Xr close
+attempt until it is able to transmit the data or until it decides it
+is unable to deliver the information (a timeout period, termed the
+linger interval, is specified in the
+.Fn setsockopt
+call when
+.Dv SO_LINGER
+is requested). 
+If
+.Dv SO_LINGER
+is disabled and a 
+.Xr close
+is issued, the system will process the close in a manner that allows
+the process to continue as quickly as possible.
+.Pp
+The option
+.Dv SO_BROADCAST
+requests permission to send broadcast datagrams
+on the socket.
+Broadcast was a privileged operation in earlier versions of the system.
+With protocols that support out-of-band data, the
+.Dv SO_OOBINLINE
+option
+requests that out-of-band data be placed in the normal data input queue
+as received; it will then be accessible with
+.Xr recv
+or
+.Xr read
+calls without the
+.Dv MSG_OOB
+flag.
+Some protocols always behave as if this option is set.
+.Dv SO_SNDBUF
+and
+.Dv SO_RCVBUF
+are options to adjust the normal
+buffer sizes allocated for output and input buffers, respectively.
+The buffer size may be increased for high-volume connections,
+or may be decreased to limit the possible backlog of incoming data.
+The system places an absolute limit on these values.
+.Pp
+.Dv SO_SNDLOWAT
+is an option to set the minimum count for output operations.
+Most output operations process all of the data supplied
+by the call, delivering data to the protocol for transmission
+and blocking as necessary for flow control.
+Nonblocking output operations will process as much data as permitted
+subject to flow control without blocking, but will process no data
+if flow control does not allow the smaller of the low water mark value
+or the entire request to be processed.
+A
+.Xr select 2
+operation testing the ability to write to a socket will return true
+only if the low water mark amount could be processed.
+The default value for
+.Dv SO_SNDLOWAT
+is set to a convenient size for network efficiency, often 1024.
+.Dv SO_RCVLOWAT
+is an option to set the minimum count for input operations.
+In general, receive calls will block until any (non-zero) amount of data
+is received, then return with the smaller of the amount available or the amount
+requested.
+The default value for
+.Dv SO_RCVLOWAT
+is 1.
+If 
+.Dv SO_RCVLOWAT
+is set to a larger value, blocking receive calls normally
+wait until they have received the smaller of the low water mark value
+or the requested amount.
+Receive calls may still return less than the low water mark if an error
+occurs, a signal is caught, or the type of data next in the receive queue
+is different than that returned.
+.Pp
+.Dv SO_SNDTIMEO
+is an option to set a timeout value for output operations.
+It accepts a
+.Fa struct timeval
+parameter with the number of seconds and microseconds
+used to limit waits for output operations to complete.
+If a send operation has blocked for this much time,
+it returns with a partial count
+or with the error
+.Er EWOULDBLOCK
+if no data were sent.
+In the current implementation, this timer is restarted each time additional
+data are delivered to the protocol,
+implying that the limit applies to output portions ranging in size
+from the low water mark to the high water mark for output.
+.Dv SO_RCVTIMEO
+is an option to set a timeout value for input operations.
+It accepts a
+.Fa struct timeval
+parameter with the number of seconds and microseconds
+used to limit waits for input operations to complete.
+In the current implementation, this timer is restarted each time additional
+data are received by the protocol,
+and thus the limit is in effect an inactivity timer.
+If a receive operation has been blocked for this much time without
+receiving additional data, it returns with a short count
+or with the error
+.Er EWOULDBLOCK
+if no data were received.
+.Pp
+Finally,
+.Dv SO_TYPE
+and
+.Dv SO_ERROR
+are options used only with
+.Fn getsockopt .
+.Dv SO_TYPE
+returns the type of the socket, such as
+.Dv SOCK_STREAM ;
+it is useful for servers that inherit sockets on startup.
+.Dv SO_ERROR
+returns any pending error on the socket and clears
+the error status.
+It may be used to check for asynchronous errors on connected
+datagram sockets or for other asynchronous errors.
+.Sh RETURN VALUES
+A 0 is returned if the call succeeds, -1 if it fails.
+.Sh ERRORS
+The call succeeds unless:
+.Bl -tag -width Er

+.Sh DESCRIPTION
+.Bf -symbolic
+Note: timezone is no longer used; this information is kept outside
+the kernel.
+.Ef
+The system's notion of the current Greenwich time and the current time
+zone is obtained with the
+.Fn gettimeofday
+call, and set with the
+.Fn settimeofday
+call.  The time is expressed in seconds and microseconds
+since midnight (0 hour), January 1, 1970.  The resolution of the system
+clock is hardware dependent, and the time may be updated continuously or
+in ``ticks.''  If
+.Fa tp
+or
+.Fa tzp
+is NULL, the associated time
+information will not be returned or set.
+.Pp
+The structures pointed to by
+.Fa tp
+and
+.Fa tzp
+are defined in 
+.Ao Pa sys/time.h Ac
+as:
+.Pp
+.Bd -literal
+struct timeval {
+	long	tv_sec;		/* seconds since Jan. 1, 1970 */
+	long	tv_usec;	/* and microseconds */
+};
+
+struct timezone {
+	int	tz_minuteswest; /* of Greenwich */
+	int	tz_dsttime;	/* type of dst correction to apply */
+};
+.Ed
+.Pp
+The 
+.Fa timezone
+structure indicates the local time zone
+(measured in minutes of time westward from Greenwich),
+and a flag that, if nonzero, indicates that
+Daylight Saving time applies locally during
+the appropriate part of the year.
+.Pp
+Only the super-user may set the time of day or time zone.
+.Sh RETURN
+A 0 return value indicates that the call succeeded.
+A -1 return value indicates an error occurred, and in this
+case an error code is stored into the global variable
+.Va errno .
+.Sh ERRORS
+The following error codes may be set in
+.Va errno :

+.Sh NAME
+.Nm intro
+.Nd introduction to system calls and error numbers
+.Sh SYNOPSIS
+.Fd #include <sys/errno.h>
+.Sh DESCRIPTION
+This section provides an overview of the system calls,
+their error returns, and other common definitions and concepts.
+.\".Pp
+.\".Sy System call restart
+.\".Pp
+.\"<more later...>
+.Sh DIAGNOSTICS
+Nearly all of the system calls provide an error number in the external
+variable
+.Va errno ,
+which is defined as:
+.Pp
+.Dl extern int errno
+.Pp
+When a system call detects an error,
+it returns an integer value
+indicating failure (usually -1)
+and sets the variable
+.Va errno
+accordingly.
+<This allows interpretation of the failure on receiving
+a -1 and to take action accordingly.>
+Successful calls never set
+.Va errno ;
+once set, it remains until another error occurs.
+It should only be examined after an error.
+Note that a number of system calls overload the meanings of these
+error numbers, and that the meanings must be interpreted according
+to the type and circumstances of the call.
+.Pp
+The following is a complete list of the errors and their
+names as given in
+.Aq Pa sys/errno.h .
+.Bl -hang -width Ds
+.It Er 0 Em "Error 0" .
+Not used.
+.It Er 1 EPERM Em "Operation not permitted" .
+An attempt was made to perform an operation limited to processes
+with appropriate privileges or to the owner of a file or other
+resources.
+.It Er 2 ENOENT Em "No such file or directory" .
+A component of a specified pathname did not exist, or the 
+pathname was an empty string.
+.It Er 3 ESRCH Em "No such process" .
+No process could be found corresponding to that specified by the given
+process ID.
+.It Er 4 EINTR Em "Interrupted function call" .
+An asynchronous signal (such as
+.Dv SIGINT
+or
+.Dv SIGQUIT )
+was caught by the process during the execution of an interruptible
+function. If the signal handler performs a normal return, the
+interrupted function call will seem to have returned the error condition.
+.It Er 5 EIO Em "Input/output error" .
+Some physical input or output error occurred.
+This error will not be reported until a subsequent operation on the same file
+descriptor and may be lost (over written) by any subsequent errors.
+.It Er 6 ENXIO Em "\&No such device or address" .
+Input or output on a special file referred to a device that did not
+exist, or
+made a request beyond the limits of the device.
+This error may also occur when, for example,
+a tape drive is not online or no disk pack is
+loaded on a drive.
+.It Er 7 E2BIG Em "Arg list too long" .
+The number of bytes used for the argument and environment
+list of the new process exceeded the current limit
+of 20480 bytes
+.Pf ( Dv NCARGS
+in
+.Aq Pa sys/param.h ) .
+.It Er 8 ENOEXEC Em "Exec format error" .
+A request was made to execute a file
+that, although it has the appropriate permissions,
+was not in the format required for an
+executable file.
+.It Er 9 EBADF Em "Bad file descriptor" .
+A file descriptor argument was out of range, referred to no open file,
+or a read (write) request was made to a file that was only open for
+writing (reading).
+.It Er 10 ECHILD Em "\&No child processes" .
+A
+.Xr wait
+or
+.Xr waitpid
+function was executed by a process that had no existing or unwaited-for
+child processes.
+.It Er 11 EDEADLK Em "Resource deadlock avoided" .
+An attempt was made to lock a system resource that
+would have resulted in a deadlock situation.
+.It Er 12 ENOMEM Em "Cannot allocate memory" .
+The new process image required more memory than was allowed by the hardware
+or by system-imposed memory management constraints.
+A lack of swap space is normally temporary; however,
+a lack of core is not.
+Soft limits may be increased to their corresponding hard limits.
+.It Er 13 EACCES Em "Permission denied" .
+An attempt was made to access a file in a way forbidden
+by its file access permissions.
+.It Er 14 EFAULT Em "Bad address" .
+The system detected an invalid address in attempting to
+use an argument of a call.
+.It Er 15 ENOTBLK Em "Not a block device" .
+A block device operation was attempted on a non-block device or file.
+.It Er 16 EBUSY Em "Resource busy" .
+An attempt to use a system resource which was in use at the time
+in a manner which would have conflicted with the request.
+.It Er 17 EEXIST Em "File exists" .
+An existing file was mentioned in an inappropriate context,
+for instance, as the new link name in a
+.Xr link
+function.
+.It Er 18 EXDEV Em "Improper link" .
+A hard link to a file on another file system
+was attempted.
+.It Er 19 ENODEV Em "Operation not supported by device" .
+An attempt was made to apply an inappropriate
+function to a device,
+for example,
+trying to read a write-only device such as a printer.
+.It Er 20 ENOTDIR Em "Not a directory" .
+A component of the specified pathname existed, but it was
+not a directory, when a directory was expected.
+.It Er 21 EISDIR Em "Is a directory" .
+An attempt was made to open a directory with write mode specified.
+.It Er 22 EINVAL Em "Invalid argument" .
+Some invalid argument was supplied. (For example,
+specifying an undefined signal to a
+.Xr signal
+or
+.Xr kill
+function).
+.It Er 23 ENFILE Em "Too many open files in system" .
+Maximum number of file descriptors allowable on the system
+has been reached and a requests for an open cannot be satisfied
+until at least one has been closed.
+.It Er 24 EMFILE Em "Too many open files" .
+<As released, the limit on the number of
+open files per process is 64.>
+.Xr Getdtablesize 2
+will obtain the current limit.
+.It Er 25 ENOTTY Em "Inappropriate ioctl for device" .
+A control function (see
+.Xr ioctl 2 )
+was attempted for a file or
+special device for which the operation was inappropriate.
+.It Er 26 ETXTBSY Em "Text file busy" .
+The new process was a pure procedure (shared text) file
+which was open for writing by another process, or
+while the pure procedure file was being executed an
+.Xr open
+call requested write access.
+.It Er 27 EFBIG Em "File too large" .
+The size of a file exceeded the maximum (about
+.if t 2\u\s-231\s+2\d
+.if n 2.1E9
+bytes).
+.It Er 28 ENOSPC Em "Device out of space" .
+A
+.Xr write
+to an ordinary file, the creation of a
+directory or symbolic link, or the creation of a directory
+entry failed because no more disk blocks were available
+on the file system, or the allocation of an inode for a newly
+created file failed because no more inodes were available
+on the file system.
+.It Er 29 ESPIPE Em "Illegal seek" .
+An
+.Xr lseek
+function was issued on a socket, pipe or
+.Tn FIFO .
+.It Er 30 EROFS Em "Read-only file system" .
+An attempt was made to modify a file or directory
+was made
+on a file system that was read-only at the time.
+.It Er 31 EMLINK Em "Too many links" .
+Maximum allowable hard links to a single file has been exceeded (limit
+of 32767 hard links per file).
+.It Er 32 EPIPE Em "Broken pipe" .
+A write on a pipe, socket or
+.Tn FIFO
+for which there is no process
+to read the data.
+.It Er 33 EDOM Em "Numerical argument out of domain" .
+A numerical input argument was outside the defined domain of the mathematical
+function.
+.It Er 34 ERANGE Em "Numerical result out of range" .
+A numerical result of the function was too large to fit in the
+available space (perhaps exceeded precision).
+.It Er 35 EAGAIN Em "Resource temporarily unavailable" .
+This is a temporary condition and later calls to the
+same routine may complete normally.
+.It Er 36 EINPROGRESS Em "Operation now in progress" .
+An operation that takes a long time to complete (such as
+a
+.Xr connect 2 )
+was attempted on a non-blocking object (see
+.Xr fcntl 2 ) .
+.It Er 37 EALREADY Em "Operation already in progress" .
+An operation was attempted on a non-blocking object that already
+had an operation in progress.
+.It Er 38 ENOTSOCK Em "Socket operation on non-socket" .
+Self-explanatory.
+.It Er 39 EDESTADDRREQ Em "Destination address required" .
+A required address was omitted from an operation on a socket.
+.It Er 40 EMSGSIZE Em "Message too long" .
+A message sent on a socket was larger than the internal message buffer
+or some other network limit.
+.It Er 41 EPROTOTYPE Em "Protocol wrong type for socket" .
+A protocol was specified that does not support the semantics of the
+socket type requested. For example, you cannot use the
+.Tn ARPA
+Internet
+.Tn UDP
+protocol with type
+.Dv SOCK_STREAM .
+.It Er 42 ENOPROTOOPT Em "Protocol not available" .
+A bad option or level was specified in a
+.Xr getsockopt 2
+or
+.Xr setsockopt 2
+call.
+.It Er 43 EPROTONOSUPPORT Em "Protocol not supported" .
+The protocol has not been configured into the
+system or no implementation for it exists.
+.It Er 44 ESOCKTNOSUPPORT Em "Socket type not supported" .
+The support for the socket type has not been configured into the
+system or no implementation for it exists.
+.It Er 45 EOPNOTSUPP Em "Operation not supported" .
+The attempted operation is not supported for the type of object referenced.
+Usually this occurs when a file descriptor refers to a file or socket
+that cannot support this operation,
+for example, trying to
+.Em accept
+a connection on a datagram socket.
+.It Er 46 EPFNOSUPPORT Em "Protocol family not supported" .
+The protocol family has not been configured into the
+system or no implementation for it exists.
+.It Er 47 EAFNOSUPPORT Em "Address family not supported by protocol family" .
+An address incompatible with the requested protocol was used.
+For example, you shouldn't necessarily expect to be able to use
+.Tn NS
+addresses with
+.Tn ARPA
+Internet protocols.
+.It Er 48 EADDRINUSE Em "Address already in use" .
+Only one usage of each address is normally permitted.
+.It Er 49 EADDRNOTAVAIL Em "Cannot assign requested address" .

+address not on this machine.
+.It Er 50 ENETDOWN Em "Network is down" .
+A socket operation encountered a dead network.
+.It Er 51 ENETUNREACH Em "Network is unreachable" .
+A socket operation was attempted to an unreachable network.
+.It Er 52 ENETRESET Em "Network dropped connection on reset" .
+The host you were connected to crashed and rebooted.
+.It Er 53 ECONNABORTED Em "Software caused connection abort" .
+A connection abort was caused internal to your host machine.
+.It Er 54 ECONNRESET Em "Connection reset by peer" .
+A connection was forcibly closed by a peer.  This normally
+results from a loss of the connection on the remote socket
+due to a timeout or a reboot.
+.It Er 55 ENOBUFS Em "\&No buffer space available" .
+An operation on a socket or pipe was not performed because
+the system lacked sufficient buffer space or because a queue was full.
+.It Er 56 EISCONN Em "Socket is already connected" .
+A
+.Xr connect
+request was made on an already connected socket; or,
+a
+.Xr sendto
+or
+.Xr sendmsg
+request on a connected socket specified a destination
+when already connected.
+.It Er 57 ENOTCONN Em "Socket is not connected" .
+An request to send or receive data was disallowed because
+the socket was not connected and (when sending on a datagram socket)
+no address was supplied.
+.It Er 58 ESHUTDOWN Em "Cannot send after socket shutdown" .
+A request to send data was disallowed because the socket
+had already been shut down with a previous
+.Xr shutdown 2
+call.
+.It Er 60 ETIMEDOUT Em "Operation timed out" .
+A
+.Xr connect
+or
+.Xr send
+request failed because the connected party did not
+properly respond after a period of time.  (The timeout
+period is dependent on the communication protocol.)
+.It Er 61 ECONNREFUSED Em "Connection refused" .
+No connection could be made because the target machine actively
+refused it.  This usually results from trying to connect
+to a service that is inactive on the foreign host.
+.It Er 62 ELOOP Em "Too many levels of symbolic links" .
+A path name lookup involved more than 8 symbolic links.
+.It Er 63 ENAMETOOLONG Em "File name too long" .
+A component of a path name exceeded 255
+.Pq Dv MAXNAMELEN
+characters, or an entire
+path name exceeded 1023
+.Pq Dv MAXPATHLEN Ns -1
+characters.
+.It Er 64 EHOSTDOWN Em "Host is down" .
+A socket operation failed because the destination host was down.
+.It Er 65 EHOSTUNREACH Em "No route to host" .
+A socket operation was attempted to an unreachable host.
+.It Er 66 ENOTEMPTY Em "Directory not empty" .
+A directory with entries other than
+.Ql \&.
+and
+.Ql \&..
+was supplied to a remove directory or rename call.
+.It Er 67 EPROCLIM Em "Too many processes" .
+.It Er 68 EUSERS Em "Too many users" .
+The quota system ran out of table entries.
+.It Er 69 EDQUOT Em "Disc quota exceeded" .
+A 
+.Xr write
+to an ordinary file, the creation of a
+directory or symbolic link, or the creation of a directory
+entry failed because the user's quota of disk blocks was
+exhausted, or the allocation of an inode for a newly
+created file failed because the user's quota of inodes
+was exhausted.
+.It Er 70 ESTALE Em "Stale NFS file handle" .
+An attempt was made to access an open file (on an
+.Tn NFS
+filesystem)
+which is now unavailable as referenced by the file descriptor.  
+This may indicate the file was deleted on the
+.Tn NFS 
+server or some 
+other catastrophic event occurred.
+.It Er 72 EBADRPC Em "RPC struct is bad" .
+Exchange of
+.Tn RPC
+information was unsuccessful.
+.It Er 73 ERPCMISMATCH Em "RPC version wrong" .
+The version of
+.Tn RPC
+on the remote peer is not compatible with

+system.
+.Sh DEFINITIONS
+.Bl -tag -width Ds
+.It  Process ID .
+Each active process in the system is uniquely identified by a non-negative
+integer called a process ID.  The range of this ID is from 0 to 30000.
+.It  Parent process ID
+A new process is created by a currently active process; (see
+.Xr fork 2 ) .
+The parent process ID of a process is initially the process ID of its creator.
+If the creating process exits,
+the parent process ID of each child is set to the ID of a system process,
+.Xr init .
+.It  Process Group
+Each active process is a member of a process group that is identified by
+a non-negative integer called the process group ID.  This is the process
+ID of the group leader.  This grouping permits the signaling of related
+processes (see
+.Xr termios 4 )
+and the job control mechanisms of
+.Xr csh 1 .
+.It Session
+A session is a set of one or more process groups.
+A session is created by a successful call to
+.Xr setsid 2 ,
+which causes the caller to become the only member of the only process
+group in the new session.
+.It Session leader
+A process that has created a new session by a successful call to
+.Xr setsid 2 ,
+is known as a session leader.
+Only a session leader may acquire a terminal as its controlling terminal (see
+.Xr termios 4 ) .
+.It Controlling process
+A session leader with a controlling terminal is a controlling process.
+.It Controlling terminal
+A terminal that is associated with a session is known as the controlling
+terminal for that session and its members.
+.It  "Terminal Process Group ID"
+A terminal may be acquired by a session leader as its controlling terminal.
+Once a terminal is associated with a session, any of the process groups
+within the session may be placed into the foreground by setting
+the terminal process group ID to the ID of the process group.
+This facility is used
+to arbitrate between multiple jobs contending for the same terminal;
+(see
+.Xr csh 1
+and
+.Xr tty 4 ) .
+.It  "Orphaned Process Group"
+A process group is considered to be
+.Em orphaned
+if it is not under the control of a job control shell.
+More precisely, a process group is orphaned
+when none of its members has a parent process that is in the same session
+as the group,
+but is in a different process group.
+Note that when a process exits, the parent process for its children
+is changed to be
+.Xr init ,
+which is in a separate session.
+Not all members of an orphaned process group are necessarily orphaned
+processes (those whose creating process has exited).
+The process group of a session leader is orphaned by definition.
+.It "Real User ID and Real Group ID"
+Each user on the system is identified by a positive integer
+termed the real user ID.
+.Pp
+Each user is also a member of one or more groups. 
+One of these groups is distinguished from others and
+used in implementing accounting facilities.  The positive
+integer corresponding to this distinguished group is termed 
+the real group ID.
+.Pp
+All processes have a real user ID and real group ID.
+These are initialized from the equivalent attributes
+of the process that created it.
+.It "Effective User Id, Effective Group Id, and Group Access List"
+Access to system resources is governed by two values:
+the effective user ID, and the group access list.
+The first member of the group access list is also known as the
+effective group ID.
+(In POSIX.1, the group access list is known as the set of supplementary
+group IDs, and it is unspecified whether the effective group ID is
+a member of the list.)
+.Pp
+The effective user ID and effective group ID are initially the
+process's real user ID and real group ID respectively.  Either
+may be modified through execution of a set-user-ID or set-group-ID
+file (possibly by one its ancestors) (see
+.Xr execve 2 ) .
+By convention, the effective group ID (the first member of the group access
+list) is duplicated, so that the execution of a set-group-ID program
+does not result in the loss of the original (real) group ID.
+.Pp
+The group access list is a set of group IDs
+used only in determining resource accessibility.  Access checks
+are performed as described below in ``File Access Permissions''.
+.It  "Saved Set User ID and Saved Set Group ID"
+When a process executes a new file, the effective user ID is set
+to the owner of the file if the file is set-user-ID, and the effective
+group ID (first element of the group access list) is set to the group
+of the file if the file is set-group-ID.
+The effective user ID of the process is then recorded as the saved set-user-ID,
+and the effective group ID of the process is recorded as the saved set-group-ID.
+These values may be used to regain those values as the effective user
+or group ID after reverting to the real ID (see
+.Xr setuid 2 ) .
+(In POSIX.1, the saved set-user-ID and saved set-group-ID are optional,
+and are used in setuid and setgid, but this does not work as desired
+for the super-user.)
+.It  Super-user
+A process is recognized as a
+.Em super-user
+process and is granted special privileges if its effective user ID is 0.
+.It  Special Processes
+The processes with process IDs of 0, 1, and 2 are special.
+Process 0 is the scheduler.  Process 1 is the initialization process
+.Xr init ,
+and is the ancestor of every other process in the system.
+It is used to control the process structure.
+Process 2 is the paging daemon.
+.It  Descriptor
+An integer assigned by the system when a file is referenced
+by
+.Xr open 2
+or
+.Xr dup 2 ,
+or when a socket is created by
+.Xr pipe 2 ,
+.Xr socket 2
+or
+.Xr socketpair 2 ,
+which uniquely identifies an access path to that file or socket from
+a given process or any of its children.
+.It  File Name
+Names consisting of up to 255
+.Pq Dv MAXNAMELEN
+characters may be used to name
+an ordinary file, special file, or directory.
+.Pp
+These characters may be selected from the set of all
+.Tn ASCII
+character
+excluding 0 (NUL) and the
+.Tn ASCII
+code for
+.Ql \&/
+(slash).  (The parity bit,
+bit 7, must be 0.)
+.Pp
+Note that it is generally unwise to use
+.Ql \&* ,
+.Ql \&? ,
+.Ql \&[
+or
+.Ql \&]
+as part of
+file names because of the special meaning attached to these characters
+by the shell.
+.It  Path Name
+A path name is a
+.Tn NUL Ns -terminated
+character string starting with an
+optional slash
+.Ql \&/ ,
+followed by zero or more directory names separated
+by slashes, optionally followed by a file name.
+The total length of a path name must be less than 1024
+.Pq Dv MAXPATHLEN
+characters.
+.Pp
+If a path name begins with a slash, the path search begins at the
+.Em root
+directory.
+Otherwise, the search begins from the current working directory.
+A slash by itself names the root directory.  An empty
+pathname refers to the current directory.
+.It  Directory
+A directory is a special type of file that contains entries
+that are references to other files.
+Directory entries are called links.  By convention, a directory
+contains at least two links,
+.Ql \&.
+and
+.Ql \&.. ,
+referred to as
+.Em dot
+and
+.Em dot-dot
+respectively.  Dot refers to the directory itself and
+dot-dot refers to its parent directory.
+.It "Root Directory and Current Working Directory"
+Each process has associated with it a concept of a root directory
+and a current working directory for the purpose of resolving path
+name searches.  A process's root directory need not be the root
+directory of the root file system.
+.It  File Access Permissions
+Every file in the file system has a set of access permissions.
+These permissions are used in determining whether a process
+may perform a requested operation on the file (such as opening
+a file for writing).  Access permissions are established at the
+time a file is created.  They may be changed at some later time
+through the 
+.Xr chmod 2
+call. 
+.Pp
+File access is broken down according to whether a file may be: read,
+written, or executed.  Directory files use the execute
+permission to control if the directory may be searched. 
+.Pp
+File access permissions are interpreted by the system as
+they apply to three different classes of users: the owner
+of the file, those users in the file's group, anyone else.
+Every file has an independent set of access permissions for
+each of these classes.  When an access check is made, the system
+decides if permission should be granted by checking the access
+information applicable to the caller.
+.Pp
+Read, write, and execute/search permissions on
+a file are granted to a process if:
+.Pp
+The process's effective user ID is that of the super-user. (Note:
+even the super-user cannot execute a non-executable file.)
+.Pp
+The process's effective user ID matches the user ID of the owner
+of the file and the owner permissions allow the access.
+.Pp
+The process's effective user ID does not match the user ID of the
+owner of the file, and either the process's effective
+group ID matches the group ID
+of the file, or the group ID of the file is in
+the process's group access list,
+and the group permissions allow the access.
+.Pp
+Neither the effective user ID nor effective group ID
+and group access list of the process
+match the corresponding user ID and group ID of the file,
+but the permissions for ``other users'' allow access.
+.Pp
+Otherwise, permission is denied.
+.It  Sockets and Address Families
+.Pp
+A socket is an endpoint for communication between processes.
+Each socket has queues for sending and receiving data.
+.Pp
+Sockets are typed according to their communications properties.
+These properties include whether messages sent and received
+at a socket require the name of the partner, whether communication
+is reliable, the format used in naming message recipients, etc.
+.Pp
+Each instance of the system supports some
+collection of socket types; consult
+.Xr socket 2
+for more information about the types available and
+their properties.
+.Pp
+Each instance of the system supports some number of sets of
+communications protocols.  Each protocol set supports addresses
+of a certain format.  An Address Family is the set of addresses
+for a specific group of protocols.  Each socket has an address
+chosen from the address family in which the socket was created.

+This can be used to check the validity of

+.Pp
+For a process to have permission to send a signal to a process designated

+function call
+atomically creates the specified directory entry (hard link)
+.Fa name2
+with the attributes of the underlying object pointed at by
+.Fa name1
+If the link is successful: the link count of the underlying object
+is incremented;
+.Fa name1
+and
+.Fa name2
+share equal access and rights
+to the
+underlying object.
+.Pp
+If
+.Fa name1
+is removed, the file
+.Fa name2
+is not deleted and the link count of the
+underlying object is
+decremented.
+.Pp
+.Fa Name1
+must exist for the hard link to
+succeed and

+.Nd reposition read/write file offset
+.Sh SYNOPSIS
+.Fd #include <unistd.h>
+.Ft off_t
+.Fn lseek "int fildes" "off_t offset" "int whence"
+.Sh DESCRIPTION
+The
+.Fn lseek
+function repositions the offset of the file descriptor
+.Fa fildes
+to the
+argument
+.Fa offset
+according to the directive
+.Fa whence.
+The argument
+.Fa fildes
+must be an open
+file descriptor.
+.Fn Lseek
+repositions the file pointer
+.Fa fildes
+as follows:
+.Bl -item -offset indent
+.It
+If
+.Fa whence
+is
+.Dv SEEK_SET ,
+the offset is set to

+.Fa offset
+bytes.
+.It
+If
+.Fa whence
+is
+.Dv SEEK_END ,
+the offset is set to the size of the
+file plus
+.Fa offset
+bytes.
+.El
+.Pp
+The
+.Fn lseek
+function allows the file offset to be set beyond the end
+of the existing end-of-file of the file. If data is later written
+at this point, subsequent reads of the data in the gap return
+bytes of zeros (until data is actually written into the gap).
+.Pp
+Some devices are incapable of seeking.  The value of the pointer
+associated with such a device is undefined.
+.Sh RETURN VALUES
+Upon successful completion,
+.Fn lseek
+returns the resulting offset location as measured in bytes from the
+beginning of the file.
+Otherwise,
+a value of -1 is returned and
+.Va errno
+is set to indicate
+the error.
+.Sh ERRORS
+.Fn Lseek
+will fail and the file pointer will remain unchanged if:

+.It Bq Er EBADF

+.Dt MLOCK 2
+.Os
+.Sh NAME
+.Nm mlock ,
+.Nm munlock
+.Nd lock (unlock) physical pages in memory
+.Sh SYNOPSIS
+.Fd #include <sys/types.h>
+.Fd #include <sys/mman.h>
+.Ft int
+.Fn mlock "caddr_t addr" "size_t len"
+.Ft int
+.Fn munlock "caddr_t addr" "size_t len"
+.Sh DESCRIPTION
+The
+.Nm mlock
+system call
+locks into memory the physical pages associated with the virtual address
+range starting at
+.Fa addr
+for
+.Fa len
+bytes.
+The
+.Nm munlock
+call unlocks pages previously locked by one or more
+.Nm mlock
+calls.
+For both, the
+.Fa addr
+parameter should be aligned to a multiple of the page size.
+If the
+.Fa len
+parameter is not a multiple of the page size, it will be rounded up
+to be so.
+The entire range must be allocated.
+.Pp
+After an
+.Nm mlock
+call, the indicated pages will cause neither a non-resident page
+nor address-translation fault until they are unlocked.
+They may still cause protection-violation faults or TLB-miss faults on
+architectures with software-managed TLBs.
+The physical pages remain in memory until all locked mappings for the pages
+are removed.
+Multiple processes may have the same physical pages locked via their own
+virtual address mappings.
+A single process may likewise have pages multiply-locked via different virtual
+mappings of the same pages or via nested
+.Nm mlock
+calls on the same address range.
+Unlocking is performed explicitly by
+.Nm munlock
+or implicitly by a call to
+.Nm munmap
+which deallocates the unmapped address range.
+Locked mappings are not inherited by the child process after a
+.Xr fork 2 .
+.Pp
+Since physical memory is a potentially scarce resource, processes are
+limited in how much they can lock down.
+A single process can
+.Nm mlock
+the minimum of
+a system-wide ``wired pages'' limit and
+the per-process
+.Li RLIMIT_MEMLOCK
+resource limit.
+.Sh RETURN VALUES
+A return value of 0 indicates that the call
+succeeded and all pages in the range have either been locked or unlocked.
+A return value of -1 indicates an error occurred and the locked
+status of all pages in the range remains unchanged.
+In this case, the global location
+.Va errno
+is set to indicate the error.
+.Sh ERRORS
+.Fn Mlock
+will fail if:
+.Bl -tag -width Er
+.It Bq Er EINVAL
+The address given is not page aligned or the length is negative.
+.It Bq Er EAGAIN
+Locking the indicated range would exceed either the system or per-process
+limit for locked memory.
+.It Bq Er ENOMEM
+Some portion of the indicated address range is not allocated.
+There was an error faulting/mapping a page.
+.El
+.Fn Munlock
+will fail if:
+.Bl -tag -width Er
+.It Bq Er EINVAL
+The address given is not page aligned or the length is negative.
+.It Bq Er ENOMEM
+Some portion of the indicated address range is not allocated.
+Some portion of the indicated address range is not locked.
+.El
+.Sh "SEE ALSO"
+.Xr fork 2 ,
+.Xr mincore 2 ,
+.Xr mmap 2 ,
+.Xr munmap 2 ,
+.Xr setrlimit 2 ,
+.Xr getpagesize 3
+.Sh BUGS
+Unlike The Sun implementation, multiple
+.Nm mlock
+calls on the same address range require the corresponding number of
+.Nm munlock
+calls to actually unlock the pages, i.e.
+.Nm mlock
+nests.
+This should be considered a consequence of the implementation
+and not a feature.
+.Pp
+The per-process resource limit is a limit on the amount of virtual
+memory locked, while the system-wide limit is for the number of locked
+physical pages.
+Hence a process with two distinct locked mappings of the same physical page
+counts as 2 pages against the per-process limit and as only a single page
+in the system limit.
+.Sh HISTORY
+The
+.Fn mlock
+and
+.Fn munlock
+functions first appeared in 4.4BSD.

+.Fn mmap "caddr_t addr" "size_t len" "int prot" "int flags" "int fd" "off_t offset"
+.Sh DESCRIPTION
+The
+.Nm mmap
+function causes the pages starting at
+.Fa addr
+and continuing for at most
+.Fa len
+bytes to be mapped from the object described by
+.Fa fd ,
+starting at byte offset
+.Fa offset .
+If
+.Fa offset
+or
+.Fa len
+is not a multiple of the pagesize, the mapped region may extend past the
+specified range.
+.Pp
+If
+.Fa addr
+is non-zero, it is used as a hint to the system.
+(As a convenience to the system, the actual address of the region may differ
+from the address supplied.)
+If
+.Fa addr
+is zero, an address will be selected by the system.
+The actual starting address of the region is returned.
+A successful
+.Fa mmap
+deletes any previous mapping in the allocated address range.
+.Pp
+The protections (region accessibility) are specified in the
+.Fa prot

+the following values:
+.Pp
+.Bl -tag -width MAP_FIXEDX
+.It Dv PROT_EXEC
+Pages may be executed.
+.It Dv PROT_READ
+Pages may be read.
+.It Dv PROT_WRITE
+Pages may be written.
+.El
+.Pp
+The
+.Fa flags
+parameter specifies the type of the mapped object, mapping options and
+whether modifications made to the mapped copy of the page are private
+to the process or are to be shared with other references.
+Sharing, mapping type and options are specified in the
+.Fa flags
+argument by
+.Em or Ns 'ing
+the following values:
+.Pp
+.Bl -tag -width MAP_FIXEDX
+.It Dv MAP_ANON
+Map anonymous memory not associated with any specific file.
+The file descriptor used for creating
+.Dv MAP_ANON
+regions is used only for
+naming, and may be specified as \-1 if no name is associated with the
+region.
+.It Dv MAP_FILE
+Mapped from a regular file or character-special device memory.  (This is
+the default mapping type, and need not be specified.)
+.It Dv MAP_FIXED
+Do not permit the system to select a different address than the one
+specified.
+If the specified address cannot be used,
+.Nm mmap
+will fail.
+If MAP_FIXED is specified,
+.Fa addr
+must be a multiple of the pagesize.
+Use of this option is discouraged.
+.It Dv MAP_HASSEMAPHORE
+Notify the kernel that the region may contain semaphores and that special
+handling may be necessary.
+.It Dv MAP_INHERIT
+Permit regions to be inherited across
+.Xr exec 2
+system calls.
+.It Dv MAP_PRIVATE
+Modifications are private.
+.It Dv MAP_SHARED
+Modifications are shared.
+.El
+.Pp
+The 
+.Xr close 2
+function does not unmap pages, see
+.Xr munmap 2
+for further information.
+.Pp
+The current design does not allow a process to specify the location of
+swap space.
+In the future we may define an additional mapping type,
+.Dv MAP_SWAP ,
+in which
+the file descriptor argument specifies a file or device to which swapping
+should be done.
+.Sh RETURN VALUES
+Upon successful completion,
+.Nm mmap
+returns a pointer to the mapped region.
+Otherwise, a value of -1 is returned and
+.Va errno
+is set to indicate the error.

+.Sh NAME
+.Nm mount ,
+.Nm unmount
+.Nd mount or dismount a file system
+.Sh SYNOPSIS
+.Fd #include <sys/param.h>
+.Fd #include <sys/mount.h>
+.Ft int
+.Fn mount "int type" "const char *dir" "int flags" "caddr_t data"
+.Ft int
+.Fn unmount "const char *dir" "int flags"
+.Sh DESCRIPTION
+The
+.Fn mount
+function grafts
+a file system object onto the system file tree
+at the point
+.Ar dir .
+The argument
+.Ar data
+describes the file system object to be mounted.
+The argument
+.Ar type
+tells the kernel how to interpret
+.Ar data
+(See
+.Ar type
+below).
+The contents of the file system
+become available through the new mount point
+.Ar dir .
+Any files in
+.Ar dir
+at the time
+of a successful mount are swept under the carpet so to speak, and
+are unavailable until the file system is unmounted.
+.Pp
+The following
+.Ar flags
+may be specified to
+suppress default semantics which affect file system access.
+.Bl -tag -width MNT_SYNCHRONOUS
+.It Dv MNT_RDONLY
+The file system should be treated as read-only;
+Even the super-user may not write on it.
+.It Dv MNT_NOEXEC
+Do not allow files to be executed from the file system.
+.It Dv MNT_NOSUID
+Do not honor setuid or setgid bits on files when executing them.
+.It Dv MNT_NODEV
+Do not interpret special files on the file system.
+.It Dv MNT_SYNCHRONOUS
+All I/O to the file system should be done synchronously.
+.El
+.Pp
+The flag
+.Dv MNT_UPDATE
+indicates that the mount command is being applied 
+to an already mounted file system.
+This allows the mount flags to be changed without requiring
+that the file system be unmounted and remounted.
+Some file systems may not allow all flags to be changed.
+For example,
+most file systems will not allow a change from read-write to read-only.
+.Pp
+The
+.Fa type
+argument defines the type of the file system.
+The types of file systems known to the system are defined in
+.Aq Pa sys/mount.h .
+.Fa Data
+is a pointer to a structure that contains the type
+specific arguments to mount.
+The currently supported types of file systems and
+their type specific data are:
+.Pp
+.Dv MOUNT_UFS
+.Bd -literal -offset indent -compact
+struct ufs_args {
+      char	*fspec;  /* Block special file to mount */
+      int	exflags; /* export related flags */
+      uid_t	exroot;  /* mapping for root uid */
+};
+.Ed
+.Pp
+.Dv MOUNT_NFS
+.Bd -literal -offset indent -compact
+struct nfs_args {
+      struct sockaddr_in *addr; /* file server address */
+      nfsv2fh_t *fh;       /* File handle to be mounted */
+      int       flags;     /* flags */
+      int       wsize;     /* write size in bytes */
+      int       rsize;     /* read size in bytes */
+      int       timeo;     /* initial timeout 0.1 secs */
+      int       retrans;   /* times to retry send */

+      char	*name;	/* name of backing process */
+      caddr_t	base;	/* base address of the file system */
+      u_long	size;	/* size of the file system */
+};
+.Ed
+.Pp
+The
+.Fn umount
+function call disassociates the file system from the specified
+mount point
+.Fa dir .
+.Pp
+The
+.Fa flags
+argument may specify
+.Dv MNT_FORCE
+to specify that the file system should be forcibly unmounted even if files are
+still active.
+Active special devices continue to work,
+but any further accesses to any other active files result in errors
+even if the file system is later remounted.
+.Sh RETURN VALUES
+The
+.Fn mount
+returns the value 0 if the mount was successful, otherwise -1 is returned
+and the variable
+.Va errno
+is set to indicate the error.
+.Pp
+.Nm Umount
+returns the value 0 if the umount succeeded; otherwise -1 is returned
+and the variable
+.Va errno
+is set to indicate the error.
+.Sh ERRORS

+The initial call has only the

+flag set to specify service for the mount point.
+If the mount point is using Kerberos, then the

+will attempt to authenticate the ticket and generate a set of credentials

+This is done by first authenticating the Kerberos ticket and then mapping

+.Nm open
+.Nd open or create a file for reading or writing
+.Sh SYNOPSIS
+.Fd #include <fcntl.h>
+.Ft int
+.Fn open "const char *path" "int flags" "mode_t mode"
+.Sh DESCRIPTION
+The file name specified by
+.Fa path
+is opened
+for reading and/or writing as specified by the
+argument
+.Fa flags
+and the file descriptor returned to the calling process.
+The
+.Fa flags
+argument may indicate the file is to be
+created if it does not exist (by specifying the
+.Dv O_CREAT
+flag), in which case the file is created with mode
+.Fa mode
+as described in
+.Xr chmod 2
+and modified by the process' umask value (see
+.Xr umask 2 ) .
+.Pp
+The flags specified are formed by
+.Em or Ns 'ing
+the following values
+.Pp
+.Bd -literal -offset indent -compact
+O_RDONLY	open for reading only
+O_WRONLY	open for writing only
+O_RDWR		open for reading and writing
+O_NONBLOCK	do not block on open or for data to become available
+O_APPEND	append on each write
+O_CREAT		create file if it does not exist
+O_TRUNC		truncate size to 0
+O_EXCL		error if create and file exists
+O_SHLOCK	atomically obtain a shared lock
+O_EXLOCK	atomically obtain an exclusive lock
+.Ed
+.Pp
+Opening a file with
+.Dv O_APPEND
+set causes each write on the file
+to be appended to the end.  If
+.Dv O_TRUNC
+is specified and the
+file exists, the file is truncated to zero length.
+If
+.Dv O_EXCL
+is set with
+.Dv O_CREAT
+and the file already
+exists,
+.Fn open
+returns an error.  This may be used to
+implement a simple exclusive access locking mechanism.
+If
+.Dv O_EXCL
+is set and the last component of the pathname is
+a symbolic link,
+.Fn open
+will fail even if the symbolic
+link points to a non-existent name.
+If the
+.Dv O_NONBLOCK
+flag is specified, do not wait for the device or file to be ready or
+available.  If the
+.Fn open
+call would result
+in the process being blocked for some reason (e.g., waiting for
+carrier on a dialup line),
+.Fn open
+returns immediately.
+This flag also has the effect of making all subsequent I/O on the open file non-blocking.
+.Pp
+When opening a file, a lock with
+.Xr flock 2
+semantics can be obtained by setting
+.Dv O_SHLOCK
+for a shared lock, or
+.Dv O_EXLOCK
+for an exclusive lock.
+If creating a file with
+.Dv O_CREAT ,
+the request for the lock will never fail
+(provided that the underlying filesystem supports locking).
+.Pp
+If successful,
+.Fn open
+returns a non-negative integer, termed a file descriptor.
+It returns -1 on failure.
+The file pointer used to mark the current position within the
+file is set to the beginning of the file.
+.Pp
+When a new file is created it is given the group of the directory
+which contains it.
+.Pp
+The new descriptor is set to remain open across
+.Xr execve
+system calls; see
+.Xr close 2
+and
+.Xr fcntl 2 .
+.Pp
+The system imposes a limit on the number of file descriptors
+open simultaneously by one process.
+.Xr Getdtablesize 2
+returns the current system limit.
+.Sh ERRORS
+The named file is opened unless:
+.Bl -tag -width Er
+.It Bq Er ENOTDIR
+A component of the path prefix is not a directory.

+.Sh DESCRIPTION
+The
+.Fn pipe
+function
+creates a

+which is an object allowing

+and allocates a pair of file descriptors.
+The first descriptor connects to the
+.Em read end
+of the pipe,
+and the second connects to the
+.Em write end  ,
+so that data written to
+.Fa fildes[1]
+appears on (i.e., can be read from)
+.Fa fildes[0] .
+This allows the output of one program to be
+sent
+to another program:
+the source's standard output is set up to be
+the write end of the pipe,
+and the sink's standard input is set up to be
+the read end of the pipe.
+The pipe itself persists until all its associated descriptors are
+closed.
+.Pp
+A pipe whose read or write end has been closed is considered
+.Em widowed .
+Writing on such a pipe causes the writing process to receive
+a
+.Dv SIGPIPE
+signal.
+Widowing a pipe is the only way to deliver end-of-file to a reader:
+after the reader consumes any buffered data, reading a widowed pipe
+returns a zero count.
+.Sh RETURN VALUES

+.Sh DESCRIPTION
+The
+.Fn profil
+function enables or disables
+program counter profiling of the current process.
+If profiling is enabled,
+then at every clock tick,
+the kernel updates an appropriate count in the
+.Fa samples
+buffer.
+.Pp
+The buffer
+.Fa samples
+contains
+.Fa size
+bytes and is divided into
+a series of 16-bit bins.
+Each bin counts the number of times the program counter
+was in a particular address range in the process
+when a clock tick occurred while profiling was enabled.
+For a given program counter address,
+the number of the corresponding bin is given
+by the relation:
+.Bd -literal -offset indent
+[(pc - offset) / 2] * scale / 65536
+.Ed
+.Pp
+The
+.Fa offset
+parameter is the lowest address at which
+the kernel takes program counter samples.
+The
+.Fa scale
+parameter ranges from 1 to 65536 and
+can be used to change the span of the bins.
+A scale of 65536 maps each bin to 2 bytes of address range;
+a scale of 32768 gives 4 bytes, 16384 gives 8 bytes and so on.
+Intermediate values provide approximate intermediate ranges.
+A
+.Fa scale
+value of 0 disables profiling.
+.Sh RETURN VALUES
+If the
+.Fa scale
+value is nonzero and the buffer

+.Fn ptrace "int request" "pid_t pid" "caddr_t addr" "int data"
+.Sh DESCRIPTION
+.Fn ptrace
+provides tracing and debugging facilities.  It allows one process (the
+.Em tracing
+process) to control another (the
+.Em traced
+process).  Most of the time, the traced process runs normally, but when
+it receives a signal
+.Po
+see
+.Xr sigaction 2
+.Pc ,
+it stops.  The tracing process is expected to notice this via
+.Xr wait 2
+or the delivery of a
+.Dv SIGCHLD
+signal, examine the state of the stopped process, and cause it to
+terminate or continue as appropriate.
+.Fn ptrace
+is the mechanism by which all this happens.
+.Pp
+The
+.Fa request
+argument specifies what operation is being performed; the meaning of
+the rest of the arguments depends on the operation, but except for one
+special case noted below, all
+.Fn ptrace
+calls are made by the tracing process, and the
+.Fa pid
+argument specifies the process ID of the traced process.
+.Fa request
+can be:
+.Bl -tag -width 12n
+.It Dv PT_TRACE_ME
+This request is the only one used by the traced process; it declares
+that the process expects to be traced by its parent.  All the other
+arguments are ignored.  (If the parent process does not expect to trace
+the child, it will probably be rather confused by the results; once the
+traced process stops, it cannot be made to continue except via
+.Eo \&
+.Fn ptrace
+.Ec \&.)
+When a process has used this request and calls
+.Xr execve 2
+or any of the routines built on it
+.Po
+such as
+.Xr execv 3
+.Pc ,
+it will stop before executing the first instruction of the new image.
+Also, any setuid or setgid bits on the executable being executed will
+be ignored.
+.It Dv PT_READ_I , Dv PT_READ_D
+These requests read a single
+.Li int
+of data from the traced process' address space.  Traditionally,
+.Fn ptrace
+has allowed for machines with distinct address spaces for instruction
+and data, which is why there are two requests: conceptually,
+.Dv PT_READ_I
+reads from the instruction space and
+.Dv PT_READ_D
+reads from the data space.  In the current NetBSD implementation, these
+two requests are completely identical.  The
+.Fa addr
+argument specifies the address (in the traced process' virtual address
+space) at which the read is to be done.  This address does not have to
+meet any alignment constraints.  The value read is returned as the
+return value from
+.Eo \&
+.Fn ptrace
+.Ec .
+.It Dv PT_WRITE_I , Dv PT_WRITE_D
+These requests parallel
+.Dv PT_READ_I
+and
+.Dv PT_READ_D ,
+except that they write rather than read.  The
+.Fa data
+argument supplies the value to be written.
+.It Dv PT_READ_U
+This request reads an
+.Li int
+from the traced process' user structure.  The
+.Fa addr
+argument specifies the location of the int relative to the base of the
+user structure; it will usually be an integer value cast to
+.Li caddr_t
+either explicitly or via the presence of a prototype for
+.Eo \&
+.Fn ptrace
+.Ec .
+Unlike
+.Dv PT_READ_I
+and
+.Dv PT_READ_D ,
+.Fa addr
+must be aligned on an
+.Li int
+boundary.  The value read is returned as the return value from
+.Eo \&
+.Fn ptrace
+.Ec .
+.It Dv PT_WRITE_U
+This request writes an
+.Li int
+into the traced process' user structure.
+.Fa addr
+specifies the offset, just as for
+.Dv PT_READ_U ,
+and
+.Fa data
+specifies the value to be written, just as for
+.Dv PT_WRITE_I
+and
+.Dv PT_WRITE_D .
+.It Dv PT_CONTINUE
+The traced process continues execution.
+.Fa addr
+is an address specifying the place where execution is to be resumed (a
+new value for the program counter), or
+.Li (caddr_t)1
+to indicate that execution is to pick up where it left off.
+.Fa data
+provides a signal number to be delivered to the traced process as it
+resumes execution, or 0 if no signal is to be sent.
+.It Dv PT_KILL
+The traced process terminates, as if
+.Dv PT_CONTINUE
+had been used with
+.Dv SIGKILL
+given as the signal to be delivered.
+.It Dv PT_ATTACH
+This request allows a process to gain control of an otherwise unrelated
+process and begin tracing it.  It does not need any cooperation from
+the to-be-traced process.  In this case,
+.Fa pid
+specifies the process ID of the to-be-traced process, and the other two
+arguments are ignored.  This request requires that the target process
+must have the same real UID as the tracing process, and that it must
+not be executing a setuid or setgid executable.  (If the tracing
+process is running as root, these restrictions do not apply.)  The
+tracing process will see the newly-traced process stop and may then
+control it as if it had been traced all along.
+.It Dv PT_DETACH
+This request is like PT_CONTINUE, except that it does not allow
+specifying an alternate place to continue execution, and after it
+succeeds, the traced process is no longer traced and continues
+execution normally.
+.El
+.Pp
+Additionally, machine-specific requests can exist.  On the SPARC, these
+are:
+.Bl -tag -width 12n
+.It Dv PT_GETREGS
+This request reads the traced process' machine registers into the
+.Dq Li "struct reg"
+(defined in
+.Aq Pa machine/reg.h )
+pointed to by
+.Fa addr .
+.It Dv PT_SETREGS
+This request is the converse of
+.Dv PT_GETREGS ;
+it loads the traced process' machine registers from the
+.Dq Li "struct reg"
+(defined in
+.Aq Pa machine/reg.h )
+pointed to by
+.Fa addr .
+.It Dv PT_GETFPREGS
+This request reads the traced process' floating-point registers into
+the
+.Dq Li "struct fpreg"
+(defined in
+.Aq Pa machine/reg.h )
+pointed to by
+.Fa addr .
+.It Dv PT_SETFPREGS
+This request is the converse of
+.Dv PT_GETFPREGS ;
+it loads the traced process' floating-point registers from the
+.Dq Li "struct fpreg"
+(defined in
+.Aq Pa machine/reg.h )
+pointed to by
+.Fa addr .
+.It Dv PT_SYSCALL
+This request is like
+.Dv PT_CONTINUE
+except that the process will stop next time it executes any system
+call.  Information about the system call can be examined with
+.Dv PT_READ_U
+and potentially modified with
+.Dv PT_WRITE_U
+through the
+.Li u_kproc.kp_proc.p_md
+element of the user structure (see below).  If the process is continued
+with another
+.Dv PT_SYSCALL
+request, it will stop again on exit from the syscall, at which point
+the return values can be examined and potentially changed.  The
+.Li u_kproc.kp_proc.p_md
+element is of type
+.Dq Li "struct mdproc" ,
+which should be declared by including
+.Aq Pa sys/param.h ,
+.Aq Pa sys/user.h ,
+and
+.Aq Pa machine/proc.h ,
+and contains the following fields (among others):
+.Bl -item -compact -offset indent
+.It
+.Li syscall_num
+.It
+.Li syscall_nargs
+.It
+.Li syscall_args[8]
+.It
+.Li syscall_err
+.It
+.Li syscall_rv[2]
+.El
+When a process stops on entry to a syscall,
+.Li syscall_num
+holds the number of the syscall,
+.Li syscall_nargs
+holds the number of arguments it expects, and
+.Li syscall_args
+holds the arguments themselves.  (Only the first
+.Li syscall_nargs
+elements of
+.Li syscall_args
+are guaranteed to be useful.)  When a process stops on exit from a
+syscall,
+.Li syscall_num
+is
+.Eo \&
+.Li -1
+.Ec ,
+.Li syscall_err
+holds the error number
+.Po
+see
+.Xr errno 2
+.Pc ,
+or 0 if no error occurred, and
+.Li syscall_rv
+holds the return values.  (If the syscall returns only one value, only
+.Li syscall_rv[0]
+is useful.)  The tracing process can modify any of these with
+.Dv PT_WRITE_U ;
+only some modifications are useful.
+.Pp
+On entry to a syscall,
+.Li syscall_num
+can be changed, and the syscall actually performed will correspond to
+the new number (it is the responsibility of the tracing process to fill
+in
+.Li syscall_args
+appropriately for the new call, but there is no need to modify
+.Eo \&
+.Li syscall_nargs
+.Ec ).
+If the new syscall number is 0, no syscall is actually performed;
+instead,
+.Li syscall_err
+and
+.Li syscall_rv
+are passed back to the traced process directly (and therefore should be
+filled in).  If the syscall number is otherwise out of range, a dummy
+syscall which simply produces an
+.Er ENOSYS
+error is effectively performed.
+.Pp
+On exit from a syscall, only
+.Li syscall_err
+and
+.Li syscall_rv
+can usefully be changed; they are set to the values returned by the
+syscall and will be passed back to the traced process by the normal
+syscall return mechanism.
+.El
+.Sh ERRORS
+Some requests can cause
+.Fn ptrace
+to return
+.Li -1
+as a non-error value; to disambiguate,
+.Va errno
+can be set to 0 before the call and checked afterwards.  The possible
+errors are:
+.Bl -tag -width 4n
+.It Bq Er ESRCH
+No process having the specified process ID exists.
+.It Bq Er EINVAL
+.Bl -bullet -compact
+.It
+A process attempted to use
+.Dv PT_ATTACH
+on itself.
+.It
+The
+.Fa request
+was not one of the legal requests.
+.It
+The
+.Fa addr
+to
+.Dv PT_READ_U
+or
+.Dv PT_WRITE_U
+was not
+.Li int Ns \&-aligned.
+.It
+The signal number (in
+.Fa data )
+to
+.Dv PT_CONTINUE
+or
+.Dv PT_SYSCALL
+was neither 0 nor a legal signal number.
+.It
+.Dv PT_GETREGS ,
+.Dv PT_SETREGS ,
+.Dv PT_GETFPREGS ,
+or
+.Dv PT_SETFPREGS
+was attempted on a process with no valid register set.  (This is
+normally true only of system processes.)
+.El
+.It Bq Er EBUSY
+.Bl -bullet -compact
+.It
+.Dv PT_ATTACH
+was attempted on a process that was already being traced.
+.It
+A request attempted to manipulate a process that was being traced by
+some process other than the one making the request.
+.It
+A request (other than
+.Dv PT_ATTACH )
+specified a process that wasn't stopped.
+.El
+.It Bq Er EPERM
+.Bl -bullet -compact
+.It
+A request (other than
+.Dv PT_ATTACH )
+attempted to manipulate a process that wasn't being traced at all.
+.It
+An attempt was made to use
+.Dv PT_ATTACH
+on a process in violation of the requirements listed under
+.Dv PT_ATTACH
+above.
+.El
+.Sh BUGS
+On the SPARC, the PC is set to the provided PC value for
+.Dv PT_CONTINUE
+and similar calls, but the NPC is set willy-nilly to 4 greater than the
+PC value.  Using
+.Dv PT_GETREGS
+and
+.Dv PT_SETREGS
+to modify the PC, passing
+.Li (caddr_t)1
+to
+.Eo \&
+.Fn ptrace
+.Ec ,
+should be able to sidestep this.
+.Pp
+Single-stepping is not available.
+.Pp
+When using
+.Dv PT_SYSCALL ,
+there is no easy way to tell whether the traced process stopped because
+it made a syscall or because a signal was sent at a moment that it just
+happened to have valid-looking garbage in its
+.Dq Li "struct mdproc" .

+operates on the given filename
+.Fa path
+for the given user
+.Fa id .
+The address of an optional command specific data structure,
+.Fa addr ,
+may be given; its interpretation
+is discussed below with each command.
+.Pp
+Currently quotas are supported only for the ``ufs'' filesystem.

+argument specifies a file from which to take the quotas.
+The quota file must exist;
+it is normally created with the 
+.Xr quotacheck 8
+program.
+The
+.Fa id
+argument is unused.
+Only the super-user may turn quotas on.
+.It Dv Q_QUOTAOFF
+Disable disk quotas for the filesystem specified by
+.Fa path .

+Only the usage fields are used.
+This call is restricted to the super-user.
+.It Dv Q_SYNC
+Update the on-disk copy of quota usages.
+The command type specifies which type of quotas are to be updated.

+.Ft int
+.Fn reboot "int howto"
+.Sh DESCRIPTION
+.Fn Reboot
+reboots the system.
+Only the super-user may reboot a machine on demand.
+However, a reboot is invoked
+automatically in the event of unrecoverable system failures.
+.Pp
+.Fa Howto
+is a mask of options; the system call interface allows the following
+options, defined in the include file
+.Aq Pa sys/reboot.h ,
+to be passed
+to the new kernel or the new bootstrap and init programs.
+.Bl -tag -width RB_INITNAMEA
+.It Dv RB_AUTOBOOT
+The default, causing the system to reboot in its usual fashion.
+.It Dv RB_ASKNAME
+Interpreted by the bootstrap program itself, causing it to
+prompt on the console as to what file should be booted.
+Normally, the system is booted from the file
+.Dq Em xx Ns No (0,0)netbsd ,
+where
+.Em xx
+is the default disk name,
+without prompting for the file name.
+.It Dv RB_DFLTROOT
+Use the compiled in root device.
+Normally, the system uses the device from which it was booted
+as the root device if possible.
+(The default behavior is dependent on the ability of the bootstrap program
+to determine the drive from which it was loaded, which is not possible
+on all systems.)
+.It Dv RB_DUMP
+Dump kernel memory before rebooting; see
+.Xr savecore 8
+for more information.
+.It Dv RB_HALT
+the processor is simply halted; no reboot takes place.
+This option should be used with caution.
+.It Dv RB_INITNAME
+An option allowing the specification of an init program (see
+.Xr init 8 )
+other than
+.Pa /sbin/init
+to be run when the system reboots.
+This switch is not currently available.
+.It Dv RB_KDB
+Load the symbol table and enable a built-in debugger in the system.
+This option will have no useful function if the kernel is not configured
+for debugging.
+Several other options have different meaning if combined
+with this option, although their use may not be possible
+via the
+.Fn reboot
+call.
+See
+.Xr kadb 4
+for more information.
+.It Dv RB_NOSYNC
+Normally, the disks are sync'd (see
+.Xr sync 8 )
+before the processor is halted or rebooted.
+This option may be useful if file system changes have been made manually
+or if the processor is on fire.
+.It Dv RB_RDONLY
+Initially mount the root file system read-only.
+This is currently the default, and this option has been deprecated.
+.It Dv RB_SINGLE
+Normally, the reboot procedure involves an automatic disk consistency
+check and then multi-user operations.
+.Dv RB_SINGLE
+prevents this, booting the system with a single-user shell
+on the console.
+.Dv RB_SINGLE
+is actually interpreted by the
+.Xr init 8
+program in the newly booted system.
+.Pp
+When no options are given (i.e.,
+.Dv RB_AUTOBOOT
+is used), the system is
+rebooted from file ``netbsd'' in the root file system of unit 0
+of a disk chosen in a processor specific way.
+An automatic consistency check of the disks is normally performed
+(see
+.Xr fsck 8 ) .
+.El
+.Sh RETURN VALUES
+If successful, this call never returns.
+Otherwise, a -1 is returned and an error is returned in the global
+variable
+.Va errno .

+.Sh NAME
+.Nm recv ,
+.Nm recvfrom ,
+.Nm recvmsg
+.Nd receive a message from a socket
+.Sh SYNOPSIS
+.Fd #include <sys/types.h>
+.Fd #include <sys/socket.h>
+.Ft ssize_t
+.Fn recv "int s" "void *buf" "size_t len" "int flags"
+.Ft ssize_t

+.Ft ssize_t
+.Fn recvmsg "int s" "struct msghdr *msg" "int flags"
+.Sh DESCRIPTION
+.Fn Recvfrom
+and
+.Fn recvmsg
+are used to receive messages from a socket,
+and may be used to receive data on a socket whether or not
+it is connection-oriented.
+.Pp
+If
+.Fa from
+is non-nil, and the socket is not connection-oriented,
+the source address of the message is filled in.
+.Fa Fromlen
+is a value-result parameter, initialized to the size of
+the buffer associated with
+.Fa from ,
+and modified on return to indicate the actual size of the
+address stored there.
+.Pp
+The 
+.Fn recv
+call is normally used only on a 
+.Em connected
+socket (see
+.Xr connect 2 )
+and is identical to
+.Fn recvfrom
+with a nil
+.Fa from
+parameter.
+As it is redundant, it may not be supported in future releases.
+.Pp
+All three routines return the length of the message on successful
+completion.
+If a message is too long to fit in the supplied buffer,
+excess bytes may be discarded depending on the type of socket
+the message is received from (see
+.Xr socket 2 ) .
+.Pp
+If no messages are available at the socket, the
+receive call waits for a message to arrive, unless
+the socket is nonblocking (see
+.Xr fcntl 2 )
+in which case the value
+-1 is returned and the external variable
+.Va errno
+set to
+.Er EAGAIN .
+The receive calls normally return any data available,
+up to the requested amount,
+rather than waiting for receipt of the full amount requested;
+this behavior is affected by the socket-level options
+.Dv SO_RCVLOWAT
+and
+.Dv SO_RCVTIMEO
+described in
+.Xr getsockopt 2 .
+.Pp
+The
+.Xr select 2
+call may be used to determine when more data arrive.
+.Pp
+The
+.Fa flags
+argument to a recv call is formed by 
+.Em or Ap ing
+one or more of the values:
+.Bl -column MSG_WAITALL -offset indent
+.It Dv MSG_OOB Ta process out-of-band data
+.It Dv MSG_PEEK Ta peek at incoming message
+.It Dv MSG_WAITALL Ta wait for full request or error
+.El
+The
+.Dv MSG_OOB
+flag requests receipt of out-of-band data
+that would not be received in the normal data stream.
+Some protocols place expedited data at the head of the normal
+data queue, and thus this flag cannot be used with such protocols.
+The MSG_PEEK flag causes the receive operation to return data
+from the beginning of the receive queue without removing that
+data from the queue.
+Thus, a subsequent receive call will return the same data.
+The MSG_WAITALL flag requests that the operation block until
+the full request is satisfied.
+However, the call may still return less data than requested
+if a signal is caught, an error or disconnect occurs,
+or the next data to be received is of a different type than that returned.
+.Pp
+The
+.Fn recvmsg
+call uses a 
+.Fa msghdr
+structure to minimize the number of directly supplied parameters.
+This structure has the following form, as defined in
+.Ao Pa sys/socket.h Ac :
+.Pp
+.Bd -literal
+struct msghdr {
+	caddr_t	msg_name;	/* optional address */
+	u_int	msg_namelen;	/* size of address */
+	struct	iovec *msg_iov;	/* scatter/gather array */
+	u_int	msg_iovlen;	/* # elements in msg_iov */
+	caddr_t	msg_control;	/* ancillary data, see below */
+	u_int	msg_controllen; /* ancillary data buffer len */
+	int	msg_flags;	/* flags on received message */
+};
+.Ed
+.Pp
+Here
+.Fa msg_name
+and
+.Fa msg_namelen
+specify the destination address if the socket is unconnected;
+.Fa msg_name
+may be given as a null pointer if no names are desired or required.
+.Fa Msg_iov
+and
+.Fa msg_iovlen
+describe scatter gather locations, as discussed in
+.Xr read 2 .
+.Fa Msg_control ,
+which has length
+.Fa msg_controllen ,
+points to a buffer for other protocol control related messages
+or other miscellaneous ancillary data.
+The messages are of the form:
+.Bd -literal
+struct cmsghdr {
+	u_int	cmsg_len;	/* data byte count, including hdr */
+	int	cmsg_level;	/* originating protocol */
+	int	cmsg_type;	/* protocol-specific type */
+/* followed by
+	u_char	cmsg_data[]; */
+};
+.Ed
+As an example, one could use this to learn of changes in the data-stream
+in XNS/SPP, or in ISO, to obtain user-connection-request data by requesting
+a recvmsg with no data buffer provided immediately after an
+.Fn accept
+call.
+.Pp
+Open file descriptors are now passed as ancillary data for
+.Dv AF_UNIX
+domain sockets, with
+.Fa cmsg_level
+set to
+.Dv SOL_SOCKET
+and
+.Fa cmsg_type
+set to
+.Dv SCM_RIGHTS .
+.Pp
+The
+.Fa msg_flags
+field is set on return according to the message received.
+.Dv MSG_EOR
+indicates end-of-record;
+the data returned completed a record (generally used with sockets of type
+.Dv SOCK_SEQPACKET ) .
+.Dv MSG_TRUNC
+indicates that
+the trailing portion of a datagram was discarded because the datagram
+was larger than the buffer supplied.
+.Dv MSG_CTRUNC
+indicates that some
+control data were discarded due to lack of space in the buffer
+for ancillary data.
+.Dv MSG_OOB
+is returned to indicate that expedited or out-of-band data were received.
+.Pp
+.Sh RETURN VALUES
+These calls return the number of bytes received, or -1
+if an error occurred.
+.Sh ERRORS
+The calls fail if:
+.Bl -tag -width Er

+If 
+.Fa to
+exists, it is first removed.
+Both 
+.Fa from
+and
+.Fa to
+must be of the same type (that is, both directories or both
+non-directories), and must reside on the same file system.
+.Pp
+.Fn Rename
+guarantees that an instance of

+.Pp
+If the final component of
+.Fa from
+is a symbolic link,
+the symbolic link is renamed,
+not the file or directory to which it points.
+.Sh CAVEAT
+The system can deadlock if a loop in the file system graph is present.
+This loop takes the form of an entry in directory

+.Sh SYNOPSIS
+.Ft int
+.Fn revoke "char *path"
+.Sh DESCRIPTION
+The
+.Nm revoke
+function invalidates all current open file descriptors in the system
+for the file named by
+.Fa path .
+Subsequent operations on any such descriptors
+fail, with the exceptions that a
+.Fn read
+from a character device file which has been revoked
+returns a count of zero (end of file),
+and a
+.Fn close
+call will succeed.
+If the file is a special file for a device which is open,
+the device close function
+is called as if all open references to the file had been closed.
+.Pp
+Access to a file may be revoked only by its owner or the super user.
+The
+.Nm revoke
+function is currently supported only for block and character special
+device files.
+It is normally used to prepare a terminal device for a new login session,
+preventing any access by a previous user of the terminal.
+.Sh RETURN VALUES
+A 0 value indicated that the call succeeded.  A \-1 return value
+indicates an error occurred and
+.Va errno
+is set to indicated the reason.
+.Sh ERRORS
+Access to the named file is revoked unless one of the following:
+.Bl -tag -width Er
+.It Bq Er ENOTDIR
+A component of the path prefix is not a directory.
+.It Bq Er ENAMETOOLONG
+A component of a pathname exceeded 255 characters,
+or an entire path name exceeded 1024 characters.
+.It Bq Er ENOENT
+The named file or a component of the path name does not exist.
+.It Bq Er EACCES
+Search permission is denied for a component of the path prefix.
+.It Bq Er ELOOP
+Too many symbolic links were encountered in translating the pathname.
+.It Bq Er EFAULT

+.Fn FD_SET fd &fdset
+.Fn FD_CLR fd &fdset
+.Fn FD_ISSET fd &fdset
+.Fn FD_ZERO &fdset
+.Sh DESCRIPTION
+.Fn Select
+examines the I/O descriptor sets whose addresses are passed in
+.Fa readfds ,
+.Fa writefds ,
+and
+.Fa exceptfds
+to see if some of their descriptors
+are ready for reading, are ready for writing, or have an exceptional
+condition pending, respectively.
+The first
+.Fa nfds
+descriptors are checked in each set;
+i.e., the descriptors from 0 through
+.Fa nfds Ns No -1
+in the descriptor sets are examined.
+On return,
+.Fn select
+replaces the given descriptor sets
+with subsets consisting of those descriptors that are ready
+for the requested operation.
+.Fn Select
+returns the total number of ready descriptors in all the sets.
+.Pp
+The descriptor sets are stored as bit fields in arrays of integers.
+The following macros are provided for manipulating such descriptor sets:
+.Fn FD_ZERO &fdset
+initializes a descriptor set
+.Fa fdset
+to the null set.
+.Fn FD_SET fd &fdset
+includes a particular descriptor
+.Fa fd
+in
+.Fa fdset .
+.Fn FD_CLR fd &fdset
+removes
+.Fa fd
+from
+.Fa fdset .
+.Fn FD_ISSET fd &fdset
+is non-zero if
+.Fa fd
+is a member of
+.Fa fdset ,
+zero otherwise.
+The behavior of these macros is undefined if
+a descriptor value is less than zero or greater than or equal to
+.Dv FD_SETSIZE ,
+which is normally at least equal
+to the maximum number of descriptors supported by the system.
+.Pp
+If
+.Fa timeout
+is a non-nil pointer, it specifies a maximum interval to wait for the
+selection to complete.  If 
+.Fa timeout
+is a nil pointer, the select blocks indefinitely.  To affect a poll, the
+.Fa timeout
+argument should be non-nil, pointing to a zero-valued timeval structure.
+.Pp
+Any of
+.Fa readfds ,
+.Fa writefds ,
+and
+.Fa exceptfds
+may be given as nil pointers if no descriptors are of interest.
+.Sh RETURN VALUES
+.Fn Select
+returns the number of ready descriptors that are contained in
+the descriptor sets,
+or -1 if an error occurred.
+If the time limit expires,
+.Fn select
+returns 0.
+If
+.Fn select
+returns with an error,
+including one due to an interrupted call,
+the descriptor sets will be unmodified.
+.Sh ERRORS
+An error return from
+.Fn select
+indicates:
+.Bl -tag -width Er
+.It Bq Er EBADF
+One of the descriptor sets specified an invalid descriptor.
+.It Bq Er EINTR
+A signal was delivered before the time limit expired and
+before any of the selected events occurred.
+.It Bq Er EINVAL
+The specified time limit is invalid.  One of its components is
+negative or too large.

+.Xr send 2 ,
+.Xr write 2
+.Sh BUGS
+Although the provision of
+.Xr getdtablesize 2
+was intended to allow user programs to be written independent
+of the kernel limit on the number of open files, the dimension
+of a sufficiently large bit field for select remains a problem.
+The default size
+.Dv FD_SETSIZE
+(currently 256) is somewhat larger than
+the current kernel limit to the number of open files.
+However, in order to accommodate programs which might potentially
+use a larger number of open files with select, it is possible
+to increase this size within a program by providing
+a larger definition of
+.Dv FD_SETSIZE
+before the inclusion of
+.Aq Pa sys/types.h .
+.Pp
+.Fn Select
+should probably return the time remaining from the original timeout,
+if any, by modifying the time value in place.
+This may be implemented in future versions of the system.
+Thus, it is unwise to assume that the timeout value will be unmodified
+by the
+.Fn select
+call.

+.Sh DESCRIPTION
+.Fn Send ,
+.Fn sendto ,
+and

+are used to transmit a message to another socket.
+.Fn Send
+may be used only when the socket is in a 
+.Em connected
+state, while 
+.Fn sendto
+and
+.Fn sendmsg
+may be used at any time.
+.Pp
+The address of the target is given by
+.Fa to
+with 
+.Fa tolen
+specifying its size.
+The length of the message is given by
+.Fa len .
+If the message is too long to pass atomically through the
+underlying protocol, the error
+.Er EMSGSIZE
+is returned, and
+the message is not transmitted.
+.Pp
+No indication of failure to deliver is implicit in a
+.Fn send .
+Locally detected errors are indicated by a return value of -1.
+.Pp
+If no messages space is available at the socket to hold
+the message to be transmitted, then
+.Fn send
+normally blocks, unless the socket has been placed in
+non-blocking I/O mode.
+The
+.Xr select 2
+call may be used to determine when it is possible to
+send more data.
+.Pp
+The
+.Fa flags
+parameter may include one or more of the following:
+.Bd -literal
+#define	MSG_OOB        0x1  /* process out-of-band data */
+#define	MSG_DONTROUTE  0x4  /* bypass routing, use direct interface */
+.Ed
+.Pp
+The flag
+.Dv MSG_OOB
+is used to send
+.Dq out-of-band
+data on sockets that support this notion (e.g.
+.Dv SOCK_STREAM ) ;
+the underlying protocol must also support
+.Dq out-of-band
+data.
+.Dv MSG_DONTROUTE
+is usually used only by diagnostic or routing programs.
+.Pp
+See 
+.Xr recv 2
+for a description of the
+.Fa msghdr
+structure.
+.Sh RETURN VALUES
+The call returns the number of characters sent, or -1
+if an error occurred.
+.Sh ERRORS
+.Fn Send ,
+.Fn sendto ,
+and
+.Fn sendmsg
+fail if:
+.Bl -tag -width Er
+.It Bq Er EBADF
+An invalid descriptor was specified.
+.It Bq Er ENOTSOCK
+The argument
+.Fa s
+is not a socket.
+.It Bq Er EFAULT
+An invalid user space address was specified for a parameter.
+.It Bq Er EMSGSIZE
+The socket requires that message be sent atomically,
+and the size of the message to be sent made this impossible.
+.It Bq Er EAGAIN
+The socket is marked non-blocking and the requested operation
+would block.
+.It Bq Er ENOBUFS
+The system was unable to allocate an internal buffer.
+The operation may succeed when buffers become available.
+.It Bq Er ENOBUFS
+The output queue for a network interface was full.
+This generally indicates that the interface has stopped sending,

+.Sh NAME
+.Nm sigaction
+.Nd software signal facilities
+.Sh SYNOPSIS
+.Fd #include <signal.h>

+struct sigaction {
+	void     (*sa_handler)();
+	sigset_t sa_mask;
+	int	 sa_flags;
+};
+.Ed
+.Ft int
+.Fn sigaction "int sig" "struct sigaction *act" "struct sigaction *oact"
+.Sh DESCRIPTION
+The system defines a set of signals that may be delivered to a process.
+Signal delivery resembles the occurrence of a hardware interrupt:
+the signal is blocked from further occurrence, the current process 
+context is saved, and a new one is built.  A process may specify a
+.Em handler
+to which a signal is delivered, or specify that a signal is to be 
+.Em ignored .
+A process may also specify that a default action is to be taken
+by the system when a signal occurs.
+A signal may also be
+.Em blocked ,
+in which case its delivery is postponed until it is
+.Em unblocked .
+The action to be taken on delivery is determined at the time
+of delivery.
+Normally, signal handlers execute on the current stack
+of the process.  This may be changed, on a per-handler basis,
+so that signals are taken on a special
+.Em "signal stack" .
+.Pp
+Signal routines execute with the signal that caused their
+invocation
+.Em blocked ,
+but other signals may yet occur.
+A global 
+.Em "signal mask"
+defines the set of signals currently blocked from delivery
+to a process.  The signal mask for a process is initialized
+from that of its parent (normally empty).  It
+may be changed with a
+.Xr sigprocmask 2
+call, or when a signal is delivered to the process.
+.Pp
+When a signal
+condition arises for a process, the signal is added to a set of
+signals pending for the process.
+If the signal is not currently
+.Em blocked
+by the process then it is delivered to the process.
+Signals may be delivered any time a process enters the operating system
+(e.g., during a system call, page fault or trap, or clock interrupt).
+If multiple signals are ready to be delivered at the same time,
+any signals that could be caused by traps are delivered first.
+Additional signals may be processed at the same time, with each
+appearing to interrupt the handlers for the previous signals
+before their first instructions.
+The set of pending signals is returned by the
+.Xr sigpending 2
+function.
+When a caught signal
+is delivered, the current state of the process is saved,
+a new signal mask is calculated (as described below), 
+and the signal handler is invoked.  The call to the handler
+is arranged so that if the signal handling routine returns
+normally the process will resume execution in the context
+from before the signal's delivery.
+If the process wishes to resume in a different context, then it
+must arrange to restore the previous context itself.
+.Pp
+When a signal is delivered to a process a new signal mask is
+installed for the duration of the process' signal handler
+(or until a
+.Xr sigprocmask
+call is made).
+This mask is formed by taking the union of the current signal mask set,
+the signal to be delivered, and 
+the signal mask associated with the handler to be invoked.
+.Pp
+.Fn Sigaction
+assigns an action for a specific signal.
+If
+.Fa act
+is non-zero, it
+specifies an action
+.Pf ( Dv SIG_DFL ,
+.Dv SIG_IGN ,
+or a handler routine) and mask
+to be used when delivering the specified signal.
+If 
+.Fa oact
+is non-zero, the previous handling information for the signal
+is returned to the user.
+.Pp
+Once a signal handler is installed, it remains installed
+until another
+.Fn sigaction
+call is made, or an 
+.Xr execve 2
+is performed.
+A signal-specific default action may be reset by
+setting
+.Fa sa_handler
+to
+.Dv SIG_DFL .
+The defaults are process termination, possibly with core dump;
+no action; stopping the process; or continuing the process.
+See the signal list below for each signal's default action.
+If
+.Fa sa_handler
+is
+.Dv SIG_DFL ,
+the default action for the signal is to discard the signal,
+and if a signal is pending,
+the pending signal is discarded even if the signal is masked.
+If
+.Fa sa_handler
+is set to
+.Dv SIG_IGN
+current and pending instances
+of the signal are ignored and discarded.
+.Pp
+Options may be specified by setting
+.Em sa_flags .
+If the
+.Dv SA_NOCLDSTOP
+bit is set when installing a catching function
+for the
+.Dv SIGCHLD
+signal,
+the
+.Dv SIGCHLD
+signal will be generated only when a child process exits,
+not when a child process stops.
+Further, if the
+.Dv SA_ONSTACK
+bit is set in
+.Em sa_flags ,
+the system will deliver the signal to the process on a
+.Em "signal stack" ,
+specified with
+.Xr sigstack 2 .
+.Pp
+If a signal is caught during the system calls listed below,
+the call may be forced to terminate
+with the error
+.Dv EINTR ,
+the call may return with a data transfer shorter than requested,
+or the call may be restarted.
+Restart of pending calls is requested
+by setting the
+.Dv SA_RESTART
+bit in
+.Ar sa_flags .
+The affected system calls include
+.Xr open 2 ,
+.Xr read 2 ,
+.Xr write 2 ,
+.Xr sendto 2 ,
+.Xr recvfrom 2 ,
+.Xr sendmsg 2
+and
+.Xr recvmsg 2
+on a communications channel or a slow device (such as a terminal,
+but not a regular file)
+and during a
+.Xr wait 2
+or
+.Xr ioctl 2 .
+However, calls that have already committed are not restarted,
+but instead return a partial success (for example, a short read count).
+.Pp
+After a
+.Xr fork 2
+or
+.Xr vfork 2
+all signals, the signal mask, the signal stack,
+and the restart/interrupt flags are inherited by the child.
+.Pp
+.Xr Execve 2
+reinstates the default
+action for all signals which were caught and
+resets all signals to be caught on the user stack.
+Ignored signals remain ignored;
+the signal mask remains the same;
+signals that restart pending system calls continue to do so.

+.Sh NAME
+.Nm sigaltstack
+.Nd set and/or get signal stack context
+.Sh SYNOPSIS
+.Fd #include <sys/types.h>
+.Fd #include <signal.h>
+.Bd -literal
+struct sigaltstack {
+	char   *ss_sp;
+	int	ss_size;
+	int     ss_flags;
+};
+.Ed
+.Ft int
+.Fn sigaltstack "const struct sigaltstack *ss" "struct sigaltstack *oss"
+.Sh DESCRIPTION
+.Fn Sigaltstack
+allows users to define an alternate stack on which signals
+are to be processed.
+If
+.Fa ss
+is non-zero,
+it specifies a pointer to and the size of a
+.Em "signal stack"
+on which to deliver signals,
+and tells the system if the process is currently executing
+on that stack.
+When a signal's action indicates its handler
+should execute on the signal stack (specified with a
+.Xr sigaction 2
+call), the system checks to see
+if the process is currently executing on that stack.
+If the process is not currently executing on the signal stack,
+the system arranges a switch to the signal stack for the
+duration of the signal handler's execution. 
+.Pp
+If
+.Dv SA_DISABLE
+is set in
+.Fa ss_flags ,
+.Fa ss_sp
+and
+.Fa ss_size
+are ignored and the signal stack will be disabled.
+Trying to disable an active stack will cause
+.Nm
+to return -1 with
+.Va errno
+set to
+.Dv EINVAL .
+A disabled stack will cause all signals to be
+taken on the regular user stack.
+If the stack is later re-enabled then all signals that were specified
+to be processed on an alternate stack will resume doing so.
+.Pp
+If
+.Fa oss
+is non-zero, the current signal stack state is returned.
+The
+.Fa ss_flags
+field will contain the value
+.Dv SA_ONSTACK
+if the process is currently on a signal stack and
+.Dv SA_DISABLE
+if the signal stack is currently disabled.
+.Sh NOTES
+The value
+.Dv SIGSTKSZ
+is defined to be the number of bytes/chars that would be used to cover
+the usual case when allocating an alternate stack area.
+The following code fragment is typically used to allocate an alternate stack.
+.Bd -literal -offset indent
+if ((sigstk.ss_sp = malloc(SIGSTKSZ)) == NULL)
+	/* error return */
+sigstk.ss_size = SIGSTKSZ;
+sigstk.ss_flags = 0;
+if (sigaltstack(&sigstk,0) < 0)
+	perror("sigaltstack");
+.Ed
+An alternative approach is provided for programs with signal handlers
+that require a specific amount of stack space other than the default size.
+The value
+.Dv MINSIGSTKSZ
+is defined to be the number of bytes/chars that is required by
+the operating system to implement the alternate stack feature.
+In computing an alternate stack size,
+programs should add
+.Dv MINSIGSTKSZ
+to their stack requirements to allow for the operating system overhead.
+.Pp
+Signal stacks are automatically adjusted for the direction of stack
+growth and alignment requirements.
+Signal stacks may or may not be protected by the hardware and
+are not ``grown'' automatically as is done for the normal stack.
+If the stack overflows and this space is not protected
+unpredictable results may occur.
+.Sh RETURN VALUES
+Upon successful completion, a value of 0 is returned.
+Otherwise, a value of -1 is returned and 
+.Va errno
+is set to indicate the error.
+.Sh ERRORS
+.Fn Sigstack
+will fail and the signal stack context will remain unchanged
+if one of the following occurs.
+.Bl -tag -width [ENOMEM]
+.It Bq Er EFAULT
+Either
+.Fa ss
+or
+.Fa oss
+points to memory that is not a valid part of the process
+address space.
+.It Bq Er EINVAL
+An attempt was made to disable an active stack.
+.It Bq Er ENOMEM
+Size of alternate stack area is less than or equal to
+.Dv MINSIGSTKSZ .

+.Sh SYNOPSIS
+.Fd #include <sys/types.h>
+.Fd #include <sys/socket.h>
+.Ft int
+.Fn socket "int domain" "int type" "int protocol"
+.Sh DESCRIPTION
+.Fn Socket
+creates an endpoint for communication and returns a descriptor.
+.Pp
+The
+.Fa domain
+parameter specifies a communications domain within which
+communication will take place; this selects the protocol family
+which should be used.
+These families are defined in the include file
+.Ao Pa sys/socket.h Ac .
+The currently understood formats are
+.Pp
+.Bd -literal -offset indent -compact
+AF_UNIX		(UNIX internal protocols),
+AF_INET		(ARPA Internet protocols),
+AF_ISO		(ISO protocols),
+AF_NS		(Xerox Network Systems protocols), and
+AF_IMPLINK	(IMP \*(lqhost at IMP\*(rq link layer).
+.Ed
+.Pp
+The socket has the indicated
+.Fa type ,
+which specifies the semantics of communication.  Currently
+defined types are:
+.Pp
+.Bd -literal -offset indent -compact
+SOCK_STREAM
+SOCK_DGRAM
+SOCK_RAW
+SOCK_SEQPACKET
+SOCK_RDM
+.Ed
+.Pp
+A
+.Dv SOCK_STREAM
+type provides sequenced, reliable,
+two-way connection based byte streams.
+An out-of-band data transmission mechanism may be supported.
+A
+.Dv SOCK_DGRAM
+socket supports
+datagrams (connectionless, unreliable messages of
+a fixed (typically small) maximum length).
+A
+.Dv SOCK_SEQPACKET
+socket may provide a sequenced, reliable,
+two-way connection-based data transmission path for datagrams
+of fixed maximum length; a consumer may be required to read
+an entire packet with each read system call.
+This facility is protocol specific, and presently implemented
+only for
+.Dv PF_NS .
+.Dv SOCK_RAW
+sockets provide access to internal network protocols and interfaces.
+The types
+.Dv SOCK_RAW ,
+which is available only to the super-user, and
+.Dv SOCK_RDM ,
+which is planned,
+but not yet implemented, are not described here.
+.Pp
+The
+.Fa protocol
+specifies a particular protocol to be used with the socket.
+Normally only a single protocol exists to support a particular
+socket type within a given protocol family.  However, it is possible
+that many protocols may exist, in which case a particular protocol
+must be specified in this manner.  The protocol number to use is
+particular to the \*(lqcommunication domain\*(rq in which communication
+is to take place; see
+.Xr protocols 5 .
+.Pp
+Sockets of type
+.Dv SOCK_STREAM
+are full-duplex byte streams, similar
+to pipes.  A stream socket must be in a
+.Em connected
+state before any data may be sent or received
+on it.  A connection to another socket is created with a
+.Xr connect 2
+call.  Once connected, data may be transferred using
+.Xr read 2
+and
+.Xr write 2
+calls or some variant of the 
+.Xr send 2
+and
+.Xr recv 2
+calls.  When a session has been completed a
+.Xr close 2
+may be performed.
+Out-of-band data may also be transmitted as described in
+.Xr send 2
+and received as described in
+.Xr recv 2 .
+.Pp
+The communications protocols used to implement a
+.Dv SOCK_STREAM
+insure that data
+is not lost or duplicated.  If a piece of data for which the
+peer protocol has buffer space cannot be successfully transmitted
+within a reasonable length of time, then
+the connection is considered broken and calls
+will indicate an error with
+-1 returns and with
+.Dv ETIMEDOUT
+as the specific code
+in the global variable
+.Va errno .
+The protocols optionally keep sockets
+.Dq warm
+by forcing transmissions
+roughly every minute in the absence of other activity.
+An error is then indicated if no response can be
+elicited on an otherwise
+idle connection for a extended period (e.g. 5 minutes).
+A
+.Dv SIGPIPE
+signal is raised if a process sends
+on a broken stream; this causes naive processes,
+which do not handle the signal, to exit.
+.Pp
+.Dv SOCK_SEQPACKET
+sockets employ the same system calls
+as
+.Dv SOCK_STREAM
+sockets.  The only difference
+is that 
+.Xr read 2
+calls will return only the amount of data requested,
+and any remaining in the arriving packet will be discarded.
+.Pp
+.Dv SOCK_DGRAM
+and
+.Dv SOCK_RAW
+sockets allow sending of datagrams to correspondents
+named in
+.Xr send 2
+calls.  Datagrams are generally received with
+.Xr recvfrom 2 ,
+which returns the next datagram with its return address.
+.Pp
+An 
+.Xr fcntl 2
+call can be used to specify a process group to receive
+a
+.Dv SIGURG
+signal when the out-of-band data arrives.
+It may also enable non-blocking I/O
+and asynchronous notification of I/O events
+via
+.Dv SIGIO .
+.Pp
+The operation of sockets is controlled by socket level
+.Em options .
+These options are defined in the file
+.Ao Pa sys/socket.h Ac .
+.Xr Setsockopt 2
+and
+.Xr getsockopt 2
+are used to set and get options, respectively.
+.Sh RETURN VALUES
+A -1 is returned if an error occurs, otherwise the return
+value is a descriptor referencing the socket.
+.Sh ERRORS
+The
+.Fn socket
+call fails if:
+.Bl -tag -width Er
+.It Bq Er EPROTONOSUPPORT
+The protocol type or the specified protocol is not supported
+within this domain.

+.Sh DESCRIPTION
+The
+.Fn stat
+function obtains information about the file pointed to by
+.Fa path .
+Read, write or execute
+permission of the named file is not required, but all directories
+listed in the path name leading to the file must be searchable.
+.Pp
+.Fn Lstat
+is like
+.Fn stat
+except in the case where the named file is a symbolic link,
+in which case
+.Fn lstat
+returns information about the link,
+while
+.Fn stat
+returns information about the file the link references.
+Unlike other filesystem objects,
+symbolic links do not have an owner, group, access mode, times, etc.
+Instead, these attributes are taken from the directory that
+contains the link.
+The only attributes returned from an
+.Fn lstat
+that refer to the symbolic link itself are the file type (S_IFLNK),
+size, blocks, and link count (always 1).
+.Pp
+The
+.Fn fstat
+obtains the same information about an open file
+known by the file descriptor
+.Fa fd .
+.Pp
+The
+.Fa sb
+argument is a pointer to a

+.Sh NAME
+.Nm vfork
+.Nd spawn new process in a virtual memory efficient way
+.Sh SYNOPSIS
+.Fd #include <unistd.h>
+.Ft pid_t
+.Fn vfork void
+.Sh DESCRIPTION
+.Fn Vfork
+can be used to create new processes without fully copying the address
+space of the old process, which is horrendously inefficient in a paged
+environment.  It is useful when the purpose of
+.Xr fork 2
+would have been to create a new system context for an
+.Xr execve .
+.Fn Vfork
+differs from
+.Xr fork
+in that the child borrows the parent's memory and thread of
+control until a call to
+.Xr execve 2
+or an exit (either by a call to
+.Xr exit 2
+or abnormally.)
+The parent process is suspended while the child is using its resources.
+.Pp
+.Fn Vfork
+returns 0 in the child's context and (later) the pid of the child in
+the parent's context.
+.Pp
+.Fn Vfork
+can normally be used just like
+.Xr fork .
+It does not work, however, to return while running in the childs context
+from the procedure that called
+.Fn vfork
+since the eventual return from
+.Fn vfork
+would then return to a no longer existent stack frame.
+Be careful, also, to call
+.Xr _exit
+rather than
+.Xr exit
+if you can't
+.Xr execve ,
+since
+.Xr exit
+will flush and close standard I/O channels, and thereby mess up the
+parent processes standard I/O data structures.
+(Even with
+.Xr fork
+it is wrong to call
+.Xr exit
+since buffered data would then be flushed twice.)
+.Sh SEE ALSO
+.Xr fork 2 ,
+.Xr execve 2 ,
+.Xr sigaction 2 ,
+.Xr wait 2 ,
+.Sh DIAGNOSTICS
+Same as for
+.Xr fork .
+.Sh BUGS
+This system call will be eliminated when proper system sharing
+mechanisms are implemented. 
+Users should not depend on the memory
+sharing semantics of
+.Xr vfork
+as it will, in that case, be made synonymous to
+.Xr fork .
+.Pp
+To avoid a possible deadlock situation,
+processes that are children in the middle
+of a
+.Fn vfork
+are never sent
+.Dv SIGTTOU
+or
+.Dv SIGTTIN
+signals; rather,

+.Ft pid_t
+.Fn wait4 "pid_t wpid" "int *status" "int options" "struct rusage *rusage"
+.Sh DESCRIPTION
+The
+.Fn wait
+function suspends execution of its calling process until
+.Fa status
+information is available for a terminated child process,
+or a signal is received.
+On return from a successful 
+.Fn wait
+call, 
+the
+.Fa status
+area contains termination information about the process that exited
+as defined below.
+.Pp
+The
+.Fn wait4
+call provides a more general interface for programs
+that need to wait for certain child processes,
+that need resource utilization statistics accumulated by child processes,
+or that require options.
+The other wait functions are implemented using
+.Fn wait4 .
+.Pp
+The
+.Fa wpid
+parameter specifies the set of child processes for which to wait.
+If
+.Fa wpid
+is -1, the call waits for any child process.
+If
+.Fa wpid
+is 0,
+the call waits for any child process in the process group of the caller.
+If
+.Fa wpid
+is greater than zero, the call waits for the process with process id
+.Fa wpid .
+If
+.Fa wpid
+is less than -1, the call waits for any process whose process group id
+equals the absolute value of
+.Fa wpid .
+.Pp
+The
+.Fa status
+parameter is defined below.  The
+.Fa options
+parameter contains the bitwise OR of any of the following options.
+The
+.Dv WNOHANG
+option
+is used to indicate that the call should not block if
+there are no processes that wish to report status.
+If the
+.Dv WUNTRACED
+option is set,
+children of the current process that are stopped
+due to a
+.Dv SIGTTIN , SIGTTOU , SIGTSTP ,
+or
+.Dv SIGSTOP
+signal also have
+their status reported.
+.Pp
+If
+.Fa rusage
+is non-zero, a summary of the resources used by the terminated
+process and all its
+children is returned (this information is currently not available
+for stopped processes).
+.Pp
+When the
+.Dv WNOHANG
+option is specified and no processes
+wish to report status, 
+.Fn wait4
+returns a 
+process id
+of 0.
+.Pp
+The
+.Fn waitpid
+call is identical to
+.Fn wait4
+with an
+.Fa rusage
+value of zero.
+The older
+.Fn wait3
+call is the same as
+.Fn wait4
+with a
+.Fa wpid
+value of -1.
+.Pp
+The following macros may be used to test the manner of exit of the process.
+One of the first three macros will evaluate to a non-zero (true) value:
+.Bl -tag -width Ds
+.It Fn WIFEXITED status
+True if the process terminated normally by a call to
+.Xr _exit 2
+or
+.Xr exit 2 .
+.It Fn WIFSIGNALED status
+True if the process terminated due to receipt of a signal.
+.It Fn WIFSTOPPED status
+True if the process has not terminated, but has stopped and can be restarted.
+This macro can be true only if the wait call specified the
+.Dv WUNTRACED
+option
+or if the child process is being traced (see
+.Xr ptrace 2 ) .
+.El
+.Pp
+Depending on the values of those macros, the following macros
+produce the remaining status information about the child process:
+.Bl -tag -width Ds
+.It Fn WEXITSTATUS status
+If
+.Fn WIFEXITED status
+is true, evaluates to the low-order 8 bits
+of the argument passed to
+.Xr _exit 2
+or
+.Xr exit 2
+by the child.
+.It Fn WTERMSIG status
+If
+.Fn WIFSIGNALED status
+is true, evaluates to the number of the signal
+that caused the termination of the process.
+.It Fn WCOREDUMP status
+If
+.Fn WIFSIGNALED status
+is true, evaluates as true if the termination
+of the process was accompanied by the creation of a core file
+containing an image of the process when the signal was received.
+.It Fn WSTOPSIG status
+If
+.Fn WIFSTOPPED status
+is true, evaluates to the number of the signal
+that caused the process to stop.
+.El
+.Sh NOTES
+See
+.Xr sigaction 2
+for a list of termination signals.
+A status of 0 indicates normal termination.
+.Pp
+If a parent process terminates without
+waiting for all of its child processes to terminate,
+the remaining child processes are assigned the parent
+process 1 ID (the init process ID).
+.Pp
+If a signal is caught while any of the
+.Fn wait
+calls is pending,
+the call may be interrupted or restarted when the signal-catching routine
+returns,
+depending on the options in effect for the signal;
+see
+.Xr intro 2 ,
+System call restart.
+.Sh RETURN VALUES
+If
+.Fn wait
+returns due to a stopped
+or terminated child process, the process ID of the child
+is returned to the calling process.  Otherwise, a value of -1
+is returned and
+.Va errno
+is set to indicate the error.
+.Pp
+If
+.Fn wait4 ,
+.Fn wait3
+or
+.Fn waitpid
+returns due to a stopped
+or terminated child process, the process ID of the child
+is returned to the calling process.
+If there are no children not previously awaited,
+-1 is returned with
+.Va errno
+set to
+.Bq Er ECHILD .
+Otherwise, if
+.Dv WNOHANG
+is specified and there are
+no stopped or exited children,
+0 is returned.
+If an error is detected or a caught signal aborts the call,
+a value of -1
+is returned and
+.Va errno
+is set to indicate the error.
+.Sh ERRORS
+.Fn Wait
+will fail and return immediately if:
+.Bl -tag -width Er
+.It Bq Er ECHILD
+The calling process has no existing unwaited-for
+child processes.
+.It Bq Er EFAULT
+The
+.Fa status
+or
+.Fa rusage
+arguments point to an illegal address.
+(May not be detected before exit of a child process.)
+.It Bq Er EINTR
+The call was interrupted by a caught signal,
+or the signal did not have the
+.Dv SA_RESTART
+flag set.
+.El
+.Sh STANDARDS
+The
+.Fn wait
+and
+.Fn waitpid
+functions are defined by POSIX;
+.Fn wait4
+and
+.Fn wait3
+are not specified by POSIX.
+The

+.Sh NAME
+.Nm write ,
+.Nm writev
+.Nd write output
+.Sh SYNOPSIS
+.Fd #include <sys/types.h>
+.Fd #include <sys/uio.h>
+.Fd #include <unistd.h>
+.Ft ssize_t
+.Fn write "int d" "const void *buf" "size_t nbytes"
+.Ft ssize_t
+.Fn writev "int d" "const struct iovec *iov" "int iovcnt"
+.Sh DESCRIPTION
+.Fn Write
+attempts to write
+.Fa nbytes
+of data to the object referenced by the descriptor
+.Fa d
+from the buffer pointed to by
+.Fa buf .
+.Fn Writev
+performs the same action, but gathers the output data
+from the 
+.Fa iovcnt
+buffers specified by the members of the
+.Fa iov
+array: iov[0], iov[1], ..., iov[iovcnt\|-\|1].
+.Pp
+For 
+.Fn writev ,
+the 
+.Fa iovec
+structure is defined as:
+.Pp
+.Bd -literal -offset indent -compact
+struct iovec {
+	void *iov_base;
+	size_t iov_len;
+};
+.Ed
+.Pp
+Each 
+.Fa iovec
+entry specifies the base address and length of an area
+in memory from which data should be written.
+.Fn Writev
+will always write a complete area before proceeding
+to the next.
+.Pp
+On objects capable of seeking, the
+.Fn write
+starts at a position
+given by the pointer associated with
+.Fa d
+(see
+.Xr lseek 2 ) .
+Upon return from
+.Fn write ,
+the pointer is incremented by the number of bytes which were written.
+.Pp
+Objects that are not capable of seeking always write from the current
+position.  The value of the pointer associated with such an object
+is undefined.
+.Pp
+If the real user is not the super-user, then
+.Fn write
+clears the set-user-id bit on a file.
+This prevents penetration of system security
+by a user who
+.Dq captures
+a writable set-user-id file
+owned by the super-user.
+.Pp
+When using non-blocking I/O on objects such as sockets that are subject
+to flow control,
+.Fn write
+and
+.Fn writev
+may write fewer bytes than requested;
+the return value must be noted,
+and the remainder of the operation should be retried when possible.
+.Sh RETURN VALUES
+Upon successful completion the number of bytes which were written
+is returned.  Otherwise a -1 is returned and the global variable
+.Va errno
+is set to indicate the error.
+.Sh ERRORS
+.Fn Write
+and
+.Fn writev
+will fail and the file pointer will remain unchanged if:
+.Bl -tag -width Er
+.It Bq Er EBADF
+.Fa D
+is not a valid descriptor open for writing.
+.It Bq Er EPIPE
+An attempt is made to write to a pipe that is not open
+for reading by any process.
+.It Bq Er EPIPE
+An attempt is made to write to a socket of type
+.DV SOCK_STREAM
+that is not connected to a peer socket.
+.It Bq Er EFBIG
+An attempt was made to write a file that exceeds the process's
+file size limit or the maximum file size.
+.It Bq Er EFAULT
+Part of
+.Fa iov
+or data to be written to the file
+points outside the process's allocated address space.
+.It Bq Er EINVAL
+The pointer associated with
+.Fa d
+was negative.
+.It Bq Er ENOSPC
+There is no free space remaining on the file system
+containing the file.
+.It Bq Er EDQUOT
+The user's quota of disk blocks on the file system
+containing the file has been exhausted.
+.It Bq Er EIO
+An I/O error occurred while reading from or writing to the file system.
+.It Bq Er EAGAIN
+The file was marked for non-blocking I/O,
+and no data could be written immediately.
+.El
+.Pp
+In addition, 
+.Fn writev
+may return one of the following errors:
+.Bl -tag -width Er
+.It Bq Er EINVAL
+.Fa Iovcnt
+was less than or equal to 0, or greater than
+.Dv {UIO_MAXIOV} .
+.It Bq Er EINVAL
+One of the
+.Fa iov_len
+values in the
+.Fa iov
+array was negative.
+.It Bq Er EINVAL
+The sum of the
+.Fa iov_len
+values in the
+.Fa iov
+array overflowed a 32-bit integer.

+has been transmitted to the terminal.
+.Pp
+The
+.Nm tcflow
+function suspends transmission of data to or the reception of data from
+the terminal referenced by
+.Fa fd
+depending on the value of
+.Fa action .
+The value of
+.Fa action
+must be one of the following:
+.Bl -tag -width "TCIOFF"
+.It Fa TCOOFF
+Suspend output.
+.It Fa TCOON

+functions are provided for getting and setting the termios structure.
+.Pp
+The
+.Nm cfgetispeed ,
+.Nm cfsetispeed ,
+.Nm cfgetospeed ,
+.Nm cfsetospeed
+and
+.Nm cfsetspeed
+functions are provided for getting and setting the baud rate values in
+the termios structure.
+The effects of the functions on the terminal as described below
+do not become effective, nor are all errors detected, until the
+.Nm tcsetattr
+function is called.
+Certain values for baud rates set in the termios structure and passed to
+.Nm tcsetattr
+have special meanings.
+These are discussed in the portion of the manual page that describes the
+.Nm tcsetattr
+function.
+.Sh GETTING AND SETTING THE BAUD RATE
+The input and output baud rates are found in the termios structure.
+The unsigned integer
+.Li speed_t
+is typdef'd in the include file
+.Aq Pa termios.h .
+The value of the integer corresponds directly to the baud rate being
+represented, however, the following symbolic values are defined.
+.Bd -literal
+#define B0	0
+#define B50	50
+#define B75	75
+#define B110	110

+#define EXTB	38400
+#endif  /*_POSIX_SOURCE */

+.Pp
+The
+.Nm cfgetispeed
+function returns the input baud rate in the termios structure referenced by
+.Fa tp .
+.Pp
+The
+.Nm cfsetispeed
+function sets the input baud rate in the termios structure referenced by
+.Fa tp
+to
+.Fa speed .
+.Pp
+The
+.Nm cfgetospeed
+function returns the output baud rate in the termios structure referenced by
+.Fa tp .
+.Pp
+The
+.Nm cfsetospeed
+function sets the output baud rate in the termios structure referenced by
+.Fa tp
+to
+.Fa speed .
+.Pp
+The
+.Nm cfsetspeed
+function sets both the input and output baud rate in the termios structure
+referenced by
+.Fa tp
+to
+.Fa speed .
+.Pp
+Upon successful completion, the functions
+.Nm cfsetispeed ,
+.Nm cfsetospeed ,
+and
+.Nm cfsetspeed
+return a value of 0.
+Otherwise, a value of -1 is returned and the global variable
+.Va errno
+is set to indicate the error.
+.Sh GETTING AND SETTING THE TERMIOS STATE
+This section describes the functions that are used to control the general
+terminal interface.
+Unless otherwise noted for a specific command, these functions are restricted
+from use by background processes.
+Attempts to perform these operations shall cause the process group to be sent
+a SIGTTOU signal.
+If the calling process is blocking or ignoring SIGTTOU signals, the process
+is allowed to perform the operation and the SIGTTOU signal is not sent.
+.Pp
+In all the functions, although
+.Fa fd
+is an open file descriptor, the functions affect the underlying terminal
+file, not just the open file description associated with the particular
+file descriptor.
+.Pp
+The
+.Nm cfmakeraw
+function sets the flags stored in the termios structure to a state disabling
+all input and output processing, giving a
+.Dq raw I/O path.
+It should be noted that there is no function to reverse this effect.
+This is because there are a variety of processing options that could be
+re-enabled and the correct method is for an application to snapshot the
+current terminal state using the function
+.Nm tcgetattr ,
+setting raw mode with
+.Nm cfmakeraw
+and the subsequent
+.Nm tcsetattr ,
+and then using another
+.Nm tcsetattr
+with the saved state to revert to the previous terminal state.
+.Pp
+The
+.Nm tcgetattr
+function copies the parameters associated with the terminal referenced
+by
+.Fa fd
+in the termios structure referenced by
+.Fa tp .
+This function is allowed from a background process, however, the terminal
+attributes may be subsequently changed by a foreground process.
+.Pp
+The
+.Nm tcsetattr
+function sets the parameters associated with the terminal from the
+termios structure referenced by
+.Fa tp .
+The
+.Fa action
+field is created by
+.Em or Ns 'ing
+the following values, as specified in the include file
+.Aq Pa termios.h .
+.Bl -tag -width "TCSADRAIN"
+.It Fa TCSANOW
+The change occurs immediately.
+.It Fa TCSADRAIN
+The change occurs after all output written to
+.Fa fd
+has been transmitted to the terminal.
+This value of
+.Fa action
+should be used when changing parameters that affect output.
+.It Fa TCSAFLUSH
+The change occurs after all output written to
+.Fa fd
+has been transmitted to the terminal
+Additionally, any input that has been received but not read is discarded.
+.It Fa TCSASOFT
+If this value is
+.Em or Ns 'ed
+into the
+.Fa action
+value, the values of the
+.Em c_cflag ,
+.Em c_ispeed ,
+and
+.Em c_ospeed
+fields are ignored.
+.El
+.Pp
+The 0 baud rate is used to terminate the connection.
+If 0 is specified as the output speed to the function
+.Nm tcsetattr ,
+modem control will no longer be asserted on the terminal, disconnecting
+the terminal.
+.Pp
+If zero is specified as the input speed to the function
+.Nm tcsetattr ,
+the input baud rate will be set to the same value as that specified by
+the output baud rate.
+.Pp
+If
+.Nm tcsetattr
+is unable able to make any of the requested changes, it returns -1 and
+sets 
+.Va errno .
+Otherwise, it makes all of the requested changes it can.
+If the specified input and output baud rates differ and are a combination
+that is not supported, neither baud rate is changed.
+.Pp
+Upon successful completion, the functions
+.Nm tcgetattr
+and
+.Nm tcsetattr
+return a value of 0.
+Otherwise, they
+return -1 and the global variable
+.Va errno
+is set to indicate the error, as follows:
+.Bl -tag -width Er
+.It Bq Er EBADF
+The
+.Fa fd
+argument to
+.Nm tcgetattr
+or

+was not a valid file descriptor.

+"What time is it?" -- Richard Deacon as The King
+"Any time you want it to be." -- Frank Baxter as The Scientist
+					(from the Bell System film on time)
+
+The 1989 update of the time zone package featured
+
+*	POSIXization (including interpretation of POSIX-style TZ environment
+	variables, provided by Guy Harris),
+*	ANSIfication (including versions of "mktime" and "difftime"),
+*	SVIDulation (an "altzone" variable)
+*	MACHination (the "gtime" function)
+*	corrections to some time zone data (including corrections to the rules
+	for Great Britain and New Zealand)
+*	reference data from the United States Naval Observatory for folks who
+	want to do additional time zones
+*	and the 1989 data for Saudi Arabia.
+
+(Since this code will be treated as "part of the implementation" in some places
+and as "part of the application" in others, there's no good way to name
+functions, such as timegm, that are not part of the proposed ANSI C standard;
+such functions have kept their old, underscore-free names in this update.)
+
+And the "dysize" function has disappeared; it was present to allow compilation
+of the "date" command on old BSD systems, and a version of "date" is now
+provided in the package.  The "date" command is not created when you "make all"
+since it may lack options provided by the version distributed with your
+operating system, or may not interact with the system in the same way the
+native version does.
+
+Since POSIX frowns on correct leap second handling, the default behavior of
+the "zic" command (in the absence of a "-L" option) has been changed to omit
+leap second information from its output files.
+
+Be sure to read the comments in "Makefile" and make any changes
+needed to make things right for your system.
+
+To use the new functions, use a "-lz" option when compiling or linking.
+
+Historical local time information has been included here not because it
+is particularly useful, but rather to:
+
+*	give an idea of the variety of local time rules that have
+	existed in the past and thus an idea of the variety that may be
+	expected in the future;
+
+*	provide a test of the generality of the local time rule description
+	system.
+
+The information in the time zone data files is by no means authoritative;
+if you know that the rules are different from those in a file, by all means
+feel free to change file (and please send the changed version to
+tz@elsie.nci.nih.gov for use in the future).  Europeans take note!

+@(#)Theory	7.2
+
+These time and date functions are much like the System V Release 2.0 (SVR2)
+time and date functions; there are a few additions and changes to extend
+the usefulness of the SVR2 functions:
+
+*	In SVR2, time display in a process is controlled by the environment
+	variable TZ, which "must be a three-letter time zone name, followed
+	by a number representing the difference between local time and
+	Greenwich Mean Time in hours, followed by an optional three-letter
+	name for a daylight time zone;" when the optional daylight time zone is
+	present, "standard U.S.A. Daylight Savings Time conversion is applied."
+	This means that SVR2 can't deal with other (for example, Australian)
+	daylight savings time rules, or situations where more than two
+	time zone abbreviations are used in an area.
+
+*	In SVR2, time conversion information is compiled into each program
+	that does time conversion.  This means that when time conversion
+	rules change (as in the United States in 1987), all programs that
+	do time conversion must be recompiled to ensure proper results.
+
+*	In SVR2, time conversion fails for near-minimum or near-maximum
+	time_t values when doing conversions for places that don't use GMT.
+
+*	In SVR2, there's no tamper-proof way for a process to learn the
+	system's best idea of local wall clock.  (This is important for
+	applications that an administrator wants used only at certain times--
+	without regard to whether the user has fiddled the "TZ" environment
+	variable.  While an administrator can "do everything in GMT" to get
+	around the problem, doing so is inconvenient and precludes handling
+	daylight savings time shifts--as might be required to limit phone
+	calls to off-peak hours.)
+
+*	These functions can account for leap seconds, thanks to Bradley White
+	(bww@k.cs.cmu.edu).
+
+These are the changes that have been made to the SVR2 functions:
+
+*	The "TZ" environment variable is used in generating the name of a file
+	from which time zone information is read (or is interpreted a la
+	POSIX); "TZ" is no longer constrained to be a three-letter time zone
+	name followed by a number of hours and an optional three-letter
+	daylight time zone name.  The daylight saving time rules to be used
+	for a particular time zone are encoded in the time zone file;
+	the format of the file allows U.S., Australian, and other rules to be
+	encoded, and allows for situations where more than two time zone
+	abbreviations are used.
+
+	It was recognized that allowing the "TZ" environment variable to
+	take on values such as "US/Eastern" might cause "old" programs
+	(that expect "TZ" to have a certain form) to operate incorrectly;
+	consideration was given to using some other environment variable
+	(for example, "TIMEZONE") to hold the string used to generate the
+	time zone information file name.  In the end, however, it was decided
+	to continue using "TZ":  it is widely used for time zone purposes;
+	separately maintaining both "TZ" and "TIMEZONE" seemed a nuisance;
+	and systems where "new" forms of "TZ" might cause problems can simply
+	use TZ values such as "EST5EDT" which can be used both by
+	"new" programs (a la POSIX) and "old" programs (as zone names and
+	offsets).
+
+*	To handle places where more than two time zone abbreviations are used,
+	the functions "localtime" and "gmtime" set tzname[tmp->tm_isdst]
+	(where "tmp" is the value the function returns) to the time zone
+	abbreviation to be used.  This differs from SVR2, where the elements
+	of tzname are only changed as a result of calls to tzset.
+
+*	Since the "TZ" environment variable can now be used to control time
+	conversion, the "daylight" and "timezone" variables are no longer
+	needed or supported.  (You can use a compile-time option to cause
+	these variables to be defined and to be set by "tzset"; however, their
+	values will not be used by "localtime.")
+
+*	The "localtime" function has been set up to deliver correct results
+	for near-minimum or near-maximum time_t values.  (A comment in the
+	source code tells how to get compatibly wrong results).
+
+*	A function "tzsetwall" has been added to arrange for the system's
+	best approximation to local wall clock time to be delivered by
+	subsequent calls to "localtime."  Source code for portable
+	applications that "must" run on local wall clock time should call
+	"tzsetwall();" if such code is moved to "old" systems that don't provide
+	tzsetwall, you won't be able to generate an executable program.
+	(These time zone functions also arrange for local wall clock time to be
+	used if tzset is called--directly or indirectly--and there's no "TZ"
+	environment variable; portable applications should not, however, rely
+	on this behavior since it's not the way SVR2 systems behave.)
+
+Points of interest to folks with Version 7 or BSD systems:
+
+*	The BSD "timezone" function is not present in this package;
+	it's impossible to reliably map timezone's arguments (a "minutes west
+	of GMT" value and a "daylight saving time in effect" flag) to a
+	time zone abbreviation, and we refuse to guess.
+	Programs that in the past used the timezone function may now examine
+	tzname[localtime(&clock)->tm_isdst] to learn the correct time
+	zone abbreviation to use.  Alternatively, use localtime(&clock)->tm_zone
+	if this has been enabled.
+
+*	The BSD gettimeofday function is not used in this package;
+	this lets users control the time zone used in doing time conversions.
+	Users who don't try to control things (that is, users who do not set
+	the environment variable TZ) get the time conversion specified in the
+	file "/etc/zoneinfo/localtime"; see the time zone compiler writeup for
+	information on how to initialize this file.
+
+The functions that are conditionally compiled if STD_INSPIRED is defined should,
+at this point, be looked on primarily as food for thought.  They are not in
+any sense "standard compatible"--some are not, in fact, specified in *any*
+standard.  They do, however, represent responses of various authors to
+standardization proposals.
+
+Other time conversion proposals, in particular the one developed by folks at
+Hewlett Packard, offer a wider selection of functions that provide capabilities
+beyond those provided here.  The absence of such functions from this package
+is not meant to discourage the development, standardization, or use of such
+functions.  Rather, their absence reflects the decision to make this package
+close to SVR2 (with the exceptions outlined above) to ensure its broad
+acceptability.  If more powerful time conversion functions can be standardized,
+so much the better.

+.SH DESCRIPTION
+.I Ctime\^
+converts a long integer, pointed to by
+.IR clock ,
+representing the time in seconds since
+00:00:00 UTC, January 1, 1970,
+and returns a pointer to a
+26-character string
+of the form

+Thu Nov 24 18:22:48 1986\n\0
+.ec
+.br
+All the fields have constant width.
+.PP
+.IR Localtime\^
+and
+.I gmtime\^
+return pointers to ``tm'' structures, described below.
+.I Localtime\^
+corrects for the time zone and any time zone adjustments
+(such as Daylight Saving Time in the U.S.A.).
+Before doing so,
+.I localtime\^
+calls
+.I tzset\^
+(if
+.I tzset\^
+has not been called in the current process).
+After filling in the ``tm'' structure,
+.I localtime
+sets the
+.BR tm_isdst 'th
+element of
+.B tzname
+to a pointer to an
+ASCII string that's the time zone abbreviation to be used with
+.IR localtime 's
+return value.
+.PP
+.I Gmtime\^
+converts to Coordinated Universal Time.
+.PP
+.I Asctime\^
+converts a time value contained in a
+``tm'' structure to a 26-character string,
+as shown in the above example,
+and returns a pointer
+to the string.
+.PP
+.I Mktime\^
+converts the broken-down time,
+expressed as local time,
+in the structure pointed to by
+.I tm
+into a calendar time value with the same encoding as that of the values
+returned by the
+.I time
+function.
+The original values of the
+.B tm_wday
+and
+.B tm_yday
+components of the structure are ignored,
+and the original values of the other components are not restricted
+to their normal ranges.
+(A positive or zero value for
+.B tm_isdst
+causes
+.I mktime
+to presume initially that summer time (for example, Daylight Saving Time
+in the U.S.A.)
+respectively,
+is or is not in effect for the specified time.
+A negative value for
+.B tm_isdst
+causes the
+.I mktime
+function to attempt to divine whether summer time is in effect
+for the specified time.)
+On successful completion, the values of the
+.B tm_wday
+and
+.B tm_yday
+components of the structure are set appropriately,
+and the other components are set to represent the specified calendar time,
+but with their values forced to their normal ranges; the final value of
+.B tm_mday
+is not set until
+.B tm_mon
+and
+.B tm_year
+are determined.
+.I Mktime\^
+returns the specified calendar time;
+If the calendar time cannot be represented,
+it returns
+.BR -1 .
+.PP
+.I Difftime\^
+returns the difference between two calendar times,
+.RI ( time1
+-
+.IR time0 ),
+expressed in seconds.
+.PP
+Declarations of all the functions and externals, and the ``tm'' structure,
+are in the
+.B <time.h>\^
+header file.

+.SH NAME
+time2posix, posix2time \- convert seconds since the Epoch
+.SH SYNOPSIS
+.nf
+.B #include <sys/types.h>
+.B #include <time.h>
+.PP
+.B time_t time2posix(t)
+.B time_t t
+.PP
+.B time_t posix2time(t)
+.B time_t t
+.PP
+.fi
+.SH DESCRIPTION
+IEEE Standard 1003.1
+(POSIX)
+legislates that a time_t value of
+536457599 shall correspond to "Wed Dec 31 23:59:59 GMT 1986."
+This effectively implies that POSIX time_t's cannot include leap
+seconds and,
+therefore,
+that the system time must be adjusted as each leap occurs.
+.PP
+If the time package is configured with leap-second support
+enabled,
+however,
+no such adjustment is needed and
+time_t values continue to increase over leap events
+(as a true `seconds since...' value).
+This means that these values will differ from those required by POSIX
+by the net number of leap seconds inserted since the Epoch.
+.PP
+Typically this is not a problem as the type time_t is intended
+to be
+(mostly)
+opaque\(emtime_t values should only be obtained-from and
+passed-to functions such as
+.IR time(2) ,
+.IR localtime(3) ,
+.IR mktime(3) ,
+and
+.IR difftime(3) .
+However,
+POSIX gives an arithmetic
+expression for directly computing a time_t value from a given date/time,
+and the same relationship is assumed by some
+(usually older)
+applications.
+Any programs creating/dissecting time_t's
+using such a relationship will typically not handle intervals
+over leap seconds correctly.
+.PP
+The
+.I time2posix
+and
+.I posix2time
+functions are provided to address this time_t mismatch by converting
+between local time_t values and their POSIX equivalents.
+This is done by accounting for the number of time-base changes that
+would have taken place on a POSIX system as leap seconds were inserted
+or deleted.
+These converted values can then be used in lieu of correcting the older
+applications,
+or when communicating with POSIX-compliant systems.
+.PP
+.I Time2posix
+is single-valued.
+That is,
+every local time_t
+corresponds to a single POSIX time_t.
+.I Posix2time
+is less well-behaved:
+for a positive leap second hit the result is not unique,
+and for a negative leap second hit the corresponding
+POSIX time_t doesn't exist so an adjacent value is returned.
+Both of these are good indicators of the inferiority of the
+POSIX representation.
+.PP
+The following table summarizes the relationship between a time
+T and it's conversion to,
+and back from,
+the POSIX representation over the leap second inserted at the end of June,
+1993.

+	[Note: posix2time(B+1) => A+0 or A+1]

+.PP
+If leap-second support is not enabled,

+.I time2posix

+.I posix2time
+degenerate to the identity function.

+.SH NAME
+tzfile \- time zone information
+.SH SYNOPSIS
+.B
+#include <tzfile.h>
+.SH DESCRIPTION
+The time zone information files used by
+.IR tzset (3)
+begin with bytes reserved for future use,
+followed by six four-byte values of type
+.BR long ,
+written in a ``standard'' byte order
+(the high-order byte of the value is written first).
+These values are,
+in order:
+.TP
+.I tzh_ttisgmtcnt
+The number of GMT/local indicators stored in the file.
+.TP
+.I tzh_ttisstdcnt
+The number of standard/wall indicators stored in the file.
+.TP
+.I tzh_leapcnt
+The number of leap seconds for which data is stored in the file.
+.TP
+.I tzh_timecnt
+The number of "transition times" for which data is stored
+in the file.
+.TP
+.I tzh_typecnt
+The number of "local time types" for which data is stored
+in the file (must not be zero).
+.TP
+.I tzh_charcnt
+The number of characters of "time zone abbreviation strings"
+stored in the file.
+.PP
+The above header is followed by
+.I tzh_timecnt
+four-byte values of type
+.BR long ,
+sorted in ascending order.
+These values are written in ``standard'' byte order.
+Each is used as a transition time (as returned by
+.IR time (2))
+at which the rules for computing local time change.
+Next come
+.I tzh_timecnt
+one-byte values of type
+.BR "unsigned char" ;
+each one tells which of the different types of ``local time'' types
+described in the file is associated with the same-indexed transition time.
+These values serve as indices into an array of
+.I ttinfo
+structures that appears next in the file;
+these structures are defined as follows:
+.in +.5i
+.sp
+.nf
+.ta .5i +\w'unsigned int\0\0'u
+struct ttinfo {
+	long	tt_gmtoff;
+	int	tt_isdst;
+	unsigned int	tt_abbrind;
+};
+.in -.5i
+.fi
+.sp
+Each structure is written as a four-byte value for
+.I tt_gmtoff
+of type
+.BR long ,
+in a standard byte order, followed by a one-byte value for
+.I tt_isdst
+and a one-byte value for
+.IR tt_abbrind .
+In each structure,
+.I tt_gmtoff
+gives the number of seconds to be added to GMT,
+.I tt_isdst
+tells whether
+.I tm_isdst
+should be set by
+.I localtime (3)
+and
+.I tt_abbrind
+serves as an index into the array of time zone abbreviation characters
+that follow the
+.I ttinfo
+structure(s) in the file.
+.PP
+Then there are
+.I tzh_leapcnt
+pairs of four-byte values, written in standard byte order;
+the first value of each pair gives the time
+(as returned by
+.IR time(2))
+at which a leap second occurs;
+the second gives the
+.I total
+number of leap seconds to be applied after the given time.
+The pairs of values are sorted in ascending order by time.
+.PP
+Then there are
+.I tzh_ttisstdcnt
+standard/wall indicators, each stored as a one-byte value;
+they tell whether the transition times associated with local time types
+were specified as standard time or wall clock time,
+and are used when a time zone file is used in handling POSIX-style
+time zone environment variables.
+.PP
+Finally there are
+.I tzh_ttisgmtcnt
+GMT/local indicators, each stored as a one-byte value;
+they tell whether the transition times associated with local time types
+were specified as GMT or local time,
+and are used when a time zone file is used in handling POSIX-style
+time zone environment variables.
+.PP
+.I Localtime
+uses the first standard-time
+.I ttinfo
+structure in the file
+(or simply the first
+.I ttinfo
+structure in the absence of a standard-time structure)
+if either
+.I tzh_timecnt
+is zero or the time argument is less than the first transition time recorded
+in the file.

+.TH TZSET 3
+.SH NAME
+tzset \- initialize time conversion information
+.SH SYNOPSIS
+.nf
+.B void tzset()
+.PP
+.fi
+.SH DESCRIPTION
+.I Tzset
+uses the value of the environment variable
+.B TZ
+to set time conversion information used by
+.IR localtime .
+If
+.B TZ
+does not appear in the environment,
+the best available approximation to local wall clock time, as specified
+by the
+.IR tzfile (5)-format
+file
+.B localtime
+in the system time conversion information directory, is used by
+.IR localtime .
+If
+.B TZ
+appears in the environment but its value is a null string,
+Coordinated Universal Time (UTC) is used (without leap second
+correction).  If
+.B TZ
+appears in the environment and its value is not a null string:
+.IP
+if the value begins with a colon, it is used as a pathname of a file
+from which to read the time conversion information;
+.IP
+if the value does not begin with a colon, it is first used as the
+pathname of a file from which to read the time conversion information,
+and, if that file cannot be read, is used directly as a specification of
+the time conversion information.
+.PP
+When
+.B TZ
+is used as a pathname, if it begins with a slash,
+it is used as an absolute pathname; otherwise,
+it is used as a pathname relative to a system time conversion information
+directory.
+The file must be in the format specified in
+.IR tzfile (5).
+.PP
+When
+.B TZ
+is used directly as a specification of the time conversion information,
+it must have the following syntax (spaces inserted for clarity):
+.IP
+\fIstd\|offset\fR[\fIdst\fR[\fIoffset\fR][\fB,\fIrule\fR]]
+.PP
+Where:
+.RS
+.TP 15
+.IR std " and " dst
+Three or more bytes that are the designation for the standard
+.RI ( std )
+or summer
+.RI ( dst )
+time zone.  Only
+.I std
+is required; if
+.I dst
+is missing, then summer time does not apply in this locale.
+Upper- and lowercase letters are explicitly allowed.  Any characters
+except a leading colon
+.RB ( : ),
+digits, comma
+.RB ( , ),
+minus
+.RB ( \(mi ),
+plus
+.RB ( \(pl ),
+and ASCII NUL are allowed.
+.TP
+.I offset
+Indicates the value one must add to the local time to arrive at
+Coordinated Universal Time.  The
+.I offset
+has the form:
+.RS
+.IP
+\fIhh\fR[\fB:\fImm\fR[\fB:\fIss\fR]]
+.RE
+.IP
+The minutes
+.RI ( mm )
+and seconds
+.RI ( ss )
+are optional.  The hour
+.RI ( hh )
+is required and may be a single digit.  The
+.I offset
+following
+.I std
+is required.  If no
+.I offset
+follows
+.IR dst ,
+summer time is assumed to be one hour ahead of standard time.  One or
+more digits may be used; the value is always interpreted as a decimal
+number.  The hour must be between zero and 24, and the minutes (and
+seconds) \(em if present \(em between zero and 59.  If preceded by a
+.RB `` \(mi '',
+the time zone shall be east of the Prime Meridian; otherwise it shall be
+west (which may be indicated by an optional preceding
+.RB `` \(pl '').
+.TP
+.I rule
+Indicates when to change to and back from summer time.  The
+.I rule
+has the form:
+.RS
+.IP
+\fIdate\fB/\fItime\fB,\fIdate\fB/\fItime\fR
+.RE
+.IP
+where the first
+.I date
+describes when the change from standard to summer time occurs and the
+second
+.I date
+describes when the change back happens.  Each
+.I time
+field describes when, in current local time, the change to the other
+time is made.
+.IP
+The format of
+.I date
+is one of the following:
+.RS
+.TP 10
+.BI J n
+The Julian day
+.I n
+.RI "(1\ \(<=" "\ n\ " "\(<=\ 365).
+Leap days are not counted; that is, in all years \(em including leap
+years \(em February 28 is day 59 and March 1 is day 60.  It is
+impossible to explicitly refer to the occasional February 29.
+.TP
+.I n
+The zero-based Julian day
+.RI "(0\ \(<=" "\ n\ " "\(<=\ 365).
+Leap days are counted, and it is possible to refer to February 29.
+.TP
+.BI M m . n . d
+The
+.IR d' th
+day
+.RI "(0\ \(<=" "\ d\ " "\(<=\ 6)
+of week
+.I n
+of month
+.I m
+of the year
+.RI "(1\ \(<=" "\ n\ " "\(<=\ 5,
+.RI "1\ \(<=" "\ m\ " "\(<=\ 12,
+where week 5 means ``the last
+.I d
+day in month
+.IR m ''
+which may occur in either the fourth or the fifth week).  Week 1 is the
+first week in which the
+.IR d' th
+day occurs.  Day zero is Sunday.
+.RE
+.IP "" 15
+The
+.I time
+has the same format as
+.I offset
+except that no leading sign
+.RB (`` \(mi ''
+or
+.RB `` \(pl '')
+is allowed.  The default, if
+.I time
+is not given, is
+.BR 02:00:00 .
+.RE
+.LP
+If no
+.I rule
+is present in
+.BR TZ ,
+the rules specified
+by the
+.IR tzfile (5)-format
+file
+.B posixrules
+in the system time conversion information directory are used, with the
+standard and summer time offsets from UTC replaced by those specified by
+the
+.I offset
+values in
+.BR TZ .
+.PP
+For compatibility with System V Release 3.1, a semicolon
+.RB ( ; )
+may be used to separate the
+.I rule
+from the rest of the specification.
+.PP
+If the
+.B TZ
+environment variable does not specify a
+.IR tzfile (5)-format
+and cannot be interpreted as a direct specification,
+UTC is used.

+.I Zic
+reads text from the file(s) named on the command line
+and creates the time conversion information files specified in this input.
+If a
+.I filename
+is
+.BR \- ,
+the standard input is read.
+.PP
+These options are available:
+.TP
+.BI "\-d " directory
+Create time conversion information files in the named directory rather than
+in the standard directory named below.
+.TP
+.BI "\-l " timezone
+Use the given time zone as local time.
+.I Zic
+will act as if the input contained a link line of the form
+.sp
+.ti +.5i
+Link	\fItimezone\fP		localtime
+.TP
+.BI "\-p " timezone
+Use the given time zone's rules when handling POSIX-format
+time zone environment variables.
+.I Zic
+will act as if the input contained a link line of the form
+.sp
+.ti +.5i
+Link	\fItimezone\fP		posixrules
+.TP
+.BI "\-L " leapsecondfilename
+Read leap second information from the file with the given name.
+If this option is not used,
+no leap second information appears in output files.
+.TP
+.B \-v
+Complain if a year that appears in a data file is outside the range
+of years representable by
+.IR time (2)
+values.
+.TP
+.B \-s
+Limit time values stored in output files to values that are the same
+whether they're taken to be signed or unsigned.
+You can use this option to generate SVVS-compatible files.
+.TP
+.BI "\-y " command
+Use the given
+.I command
+rather than
+.B yearistype
+when checking year types (see below).
+.PP
+Input lines are made up of fields.
+Fields are separated from one another by any number of white space characters.
+Leading and trailing white space on input lines is ignored.
+An unquoted sharp character (#) in the input introduces a comment which extends
+to the end of the line the sharp character appears on.
+White space characters and sharp characters may be enclosed in double quotes
+(") if they're to be used as part of a field.
+Any line that is blank (after comment stripping) is ignored.
+Non-blank lines are expected to be of one of three types:
+rule lines, zone lines, and link lines.
+.PP
+A rule line has the form
+.nf
+.ti +.5i
+.ta \w'Rule\0\0'u +\w'NAME\0\0'u +\w'FROM\0\0'u +\w'1973\0\0'u +\w'TYPE\0\0'u +\w'Apr\0\0'u +\w'lastSun\0\0'u +\w'2:00\0\0'u +\w'SAVE\0\0'u
+.sp
+Rule	NAME	FROM	TO	TYPE	IN	ON	AT	SAVE	LETTER/S
+.sp
+For example:
+.ti +.5i
+.sp
+Rule	US	1967	1973	\-	Apr	lastSun	2:00	1:00	D
+.sp
+.fi
+The fields that make up a rule line are:
+.TP "\w'LETTER/S'u"
+.B NAME
+Gives the (arbitrary) name of the set of rules this rule is part of.
+.TP
+.B FROM
+Gives the first year in which the rule applies.
+Any integer year can be supplied; the Gregorian calendar is assumed.
+The word
+.B minimum
+(or an abbreviation) means the minimum year representable as an integer.
+The word
+.B maximum
+(or an abbreviation) means the maximum year representable as an integer.
+Rules can describe times that are not representable as time values,
+with the unrepresentable times ignored; this allows rules to be portable
+among hosts with differing time value types.
+.TP
+.B TO
+Gives the final year in which the rule applies.
+In addition to
+.B minimum
+and
+.B maximum
+(as above),
+the word
+.B only
+(or an abbreviation)
+may be used to repeat the value of the
+.B FROM
+field.
+.TP
+.B TYPE
+Gives the type of year in which the rule applies.
+If
+.B TYPE
+is
+.B \-
+then the rule applies in all years between
+.B FROM
+and
+.B TO
+inclusive.
+If
+.B TYPE
+is something else, then
+.I zic
+executes the command
+.ti +.5i
+\fByearistype\fP \fIyear\fP \fItype\fP
+.br
+to check the type of a year:
+an exit status of zero is taken to mean that the year is of the given type;
+an exit status of one is taken to mean that the year is not of the given type.
+.TP
+.B IN
+Names the month in which the rule takes effect.
+Month names may be abbreviated.
+.TP
+.B ON
+Gives the day on which the rule takes effect.
+Recognized forms include:
+.nf
+.in +.5i
+.sp
+.ta \w'Sun<=25\0\0'u
+5	the fifth of the month
+lastSun	the last Sunday in the month
+lastMon	the last Monday in the month
+Sun>=8	first Sunday on or after the eighth
+Sun<=25	last Sunday on or before the 25th
+.fi
+.in -.5i
+.sp
+Names of days of the week may be abbreviated or spelled out in full.
+Note that there must be no spaces within the
+.B ON
+field.
+.TP
+.B AT
+Gives the time of day at which the rule takes effect.
+Recognized forms include:
+.nf
+.in +.5i
+.sp
+.ta \w'1:28:13\0\0'u
+2	time in hours
+2:00	time in hours and minutes
+15:00	24-hour format time (for times after noon)
+1:28:14	time in hours, minutes, and seconds
+.fi
+.in -.5i
+.sp
+Any of these forms may be followed by the letter
+.B w
+if the given time is local
+.q "wall clock"
+time,
+.B s
+if the given time is local
+.q standard
+time, or
+.B u
+(or
+.B g
+or
+.BR z )
+if the given time is universal time;
+in the absence of an indicator,
+wall clock time is assumed.
+.TP
+.B SAVE
+Gives the amount of time to be added to local standard time when the rule is in
+effect.
+This field has the same format as the
+.B AT
+field
+(although, of course, the
+.B w
+and
+.B s
+suffixes are not used).
+.TP
+.B LETTER/S
+Gives the
+.q "variable part"
+(for example, the
+.q S
+or
+.q D
+in
+.q EST
+or
+.q EDT )
+of time zone abbreviations to be used when this rule is in effect.
+If this field is
+.BR \- ,
+the variable part is null.
+.PP
+A zone line has the form
+.sp
+.nf
+.ti +.5i
+.ta \w'Zone\0\0'u +\w'Australia/Adelaide\0\0'u +\w'GMTOFF\0\0'u +\w'RULES/SAVE\0\0'u +\w'FORMAT\0\0'u
+Zone	NAME	GMTOFF	RULES/SAVE	FORMAT	[UNTIL]
+.sp
+For example:
+.sp
+.ti +.5i
+Zone	Australia/Adelaide	9:30	Aus	CST	1971 Oct 31 2:00
+.sp
+.fi
+The fields that make up a zone line are:
+.TP "\w'GMTOFF'u"
+.B NAME
+The name of the time zone.
+This is the name used in creating the time conversion information file for the
+zone.
+.TP
+.B GMTOFF
+The amount of time to add to GMT to get standard time in this zone.
+This field has the same format as the
+.B AT
+and
+.B SAVE
+fields of rule lines;
+begin the field with a minus sign if time must be subtracted from GMT.
+.TP
+.B RULES/SAVE
+The name of the rule(s) that apply in the time zone or,
+alternately, an amount of time to add to local standard time.
+If this field is
+.B \-
+then standard time always applies in the time zone.
+.TP
+.B FORMAT
+The format for time zone abbreviations in this time zone.
+The pair of characters
+.B %s
+is used to show where the
+.q "variable part"
+of the time zone abbreviation goes.
+Alternately,
+a slash (/)
+separates standard and daylight abbreviations.
+.TP
+.B UNTIL
+The time at which the GMT offset or the rule(s) change for a location.
+It is specified as a year, a month, a day, and a time of day.
+If this is specified,
+the time zone information is generated from the given GMT offset
+and rule change until the time specified.
+.IP
+The next line must be a
+.q continuation
+line; this has the same form as a zone line except that the
+string
+.q Zone
+and the name are omitted, as the continuation line will
+place information starting at the time specified as the
+.B UNTIL
+field in the previous line in the file used by the previous line.
+Continuation lines may contain an
+.B UNTIL
+field, just as zone lines do, indicating that the next line is a further
+continuation.
+.PP
+A link line has the form
+.sp
+.nf
+.ti +.5i
+.if t .ta \w'Link\0\0'u +\w'LINK-FROM\0\0'u
+.if n .ta \w'Link\0\0'u +\w'US/Eastern\0\0'u
+Link	LINK-FROM	LINK-TO
+.sp
+For example:
+.sp
+.ti +.5i
+Link	US/Eastern	EST5EDT
+.sp
+.fi
+The
+.B LINK-FROM
+field should appear as the
+.B NAME
+field in some zone line;
+the
+.B LINK-TO
+field is used as an alternate name for that zone.
+.PP
+Except for continuation lines,
+lines may appear in any order in the input.
+.PP
+Lines in the file that describes leap seconds have the following form:
+.nf
+.ti +.5i
+.ta \w'Leap\0\0'u +\w'YEAR\0\0'u +\w'MONTH\0\0'u +\w'DAY\0\0'u +\w'HH:MM:SS\0\0'u +\w'CORR\0\0'u
+.sp
+Leap	YEAR	MONTH	DAY	HH:MM:SS	CORR	R/S
+.sp
+For example:
+.ti +.5i
+.sp
+Leap	1974	Dec	31	23:59:60	+	S
+.sp
+.fi
+The
+.BR YEAR ,
+.BR MONTH ,
+.BR DAY ,
+and
+.B HH:MM:SS
+fields tell when the leap second happened.
+The
+.B CORR
+field
+should be
+.q +
+if a second was added
+or
+.q -
+if a second was skipped.
+.\" There's no need to document the following, since it's impossible for more
+.\" than one leap second to be inserted or deleted at a time.
+.\" The C Standard is in error in suggesting the possibility.
+.\" See Terry J Quinn, The BIPM and the accurate measure of time,
+.\" Proc IEEE 79, 7 (July 1991), 894-905.
+.\"	or
+.\"	.q ++
+.\"	if two seconds were added
+.\"	or
+.\"	.q --
+.\"	if two seconds were skipped.
+The
+.B R/S
+field
+should be (an abbreviation of)
+.q Stationary
+if the leap second time given by the other fields should be interpreted as GMT
+or
+(an abbreviation of)
+.q Rolling
+if the leap second time given by the other fields should be interpreted as
+local wall clock time.
+.SH NOTE
+For areas with more than two types of local time,
+you may need to use local standard time in the
+.B AT
+field of the earliest transition time's rule to ensure that
+the earliest transition time recorded in the compiled file is correct.

+.Sh DESCRIPTION
+The
+.Nm ypclnt
+suite provides an interface to the YP subsystem.  For a general description
+of the YP subsystem, see
+.Xr yp 8 .
+.Pp
+For all functions, input values begin with
+.Pa in
+and output values begin with
+.Pa out .
+Any output values of type
+.Em char **
+should be the addresses of uninitialized character pointers.  Memory will be
+allocated by the YP client routines using
+.Fn malloc .
+This memory can later be freed by the user if there is no additional need for
+the data stored there.  For
+.Pa outkey
+and
+.Pa outval ,
+two extra bytes of memory are allocated for a
+.Ql \en
+and
+.Ql \e0 ,
+which are not
+reflected in the values of
+.Pa outkeylen
+or
+.Pa outvallen .
+All occurrences of
+.Pa indomain
+and
+.Pa inmap
+must be non-null, null-terminated strings.  All input strings which also have
+a corresponding length parameter cannot be null unless the corresponding
+length value is zero.  Such strings need not be null-terminated.
+.Pp
+All YP lookup calls (the functions
+.Fn yp_all ,
+.Fn yp_first ,
+.Fn yp_master ,
+.Fn yp_match ,
+.Fn yp_next ,
+.Fn yp_order )
+require a YP domain name and a YP map name.  The default domain name may be 
+obtained by calling
+.Fn yp_get_default_domain ,
+and should thus be used before all other YP calls in a client program.
+The value it places
+.Pa outdomain
+is suitable for use as the
+.Pa indomain
+parameter to all subsequent YP calls.
+.Pp
+In order for YP lookup calls to succeed, the client process must be bound
+to a YP server process.  The client process need not explicitly bind to
+the server, as it happens automatically whenever a lookup occurs.
+The function
+.Fn yp_bind
+is provided for a backup strategy, e.g. a local file, when a YP server process
+is not available.  Each binding uses one socket descriptor on the client
+process, which may be explicitly freed using
+.Fn yp_unbind ,
+which frees all per-process and per-node resources to bind the domain and
+marks the domain unbound.
+.Pp
+If, during a YP lookup, an RPC failure occurs, the domain used in the lookup
+is automatically marked unbound and the
+.Nm ypclnt
+layer retries the lookup as long as
+.Xr ypbind 8
+is running and either the client process cannot bind to a server for the domain
+specified in the lookup, or RPC requests to the YP server process fail.
+If an error is not RPC-related, one of the YP error codes described below
+is returned and control given back to the user code.
+.Pp
+The
+.Nm ypclnt
+suite provides the following functionality:
+.Bl -tag -width Fn yp_match
+.It Fn yp_match
+Provides the value associated with the given key.
+.It Fn yp_first
+Provides the first key-value pair from the given map in the named domain.
+.It Fn yp_next
+Provides the next key-value pair in the given map.  To obtain the second pair,
+the
+.Pa inkey
+value should be the
+.Pa outkey
+value provided by the initial call to
+.Fn yp_first .
+In the general case, the next key-value pair may be obtained by using the
+.Pa outkey
+value from the previous call to
+.Fn yp_next
+as the value for
+.Pa inkey .
+.Pp
+Of course, the notions of ``first'' and ``next'' are particular to the
+type of YP map being accessed, and thus there is no guarantee of lexical
+order.  The only guarantees provided with
+.Fn yp_first
+and
+.Fn yp_next ,
+providing that the same map on the same server is polled repeatedly
+until
+.Fn yp_next
+returns YPERR_NOMORE, are that all key-value pairs in that map will be accessed
+exactly once, and if the entire procedure is repeated, the order will be
+the same.
+.Pp
+If the server is heaviliy loaded or the server fails for some reason, the
+domain being used may become unbound.  If this happens, and the client process
+re-binds, the retrieval rules will break: some entries may be seen twice, and
+others not at all.  For this reason, the function
+.Fn yp_all
+provides a better solution for reading all of the entries in a particular
+map.
+.It Fn yp_all
+This function provides a way to transfer an entire an entire map from
+the server to the client process with a single request.  This transfer
+uses TCP, unlike all other functions in the
+.Nm ypclnt
+suite, which use UDP.  The entire transaction occurs in a single RPC
+request-response.  The third argument to this function provides a way
+to supply the name of a function to process each key-value pair in the
+map.
+.Fn Yp_all
+returns after the entire transaction is complete, or the
+.Pa foreach
+function decides that it does not want any more key-value pairs.  The third
+argument to
+.Fn yp_all
+is:
+.Bd -literal -offset indent
+struct ypall_callback *incallback {
+	int (*foreach)();
+	char *data;
+};
+.Ed
+.Pp
+The
+.Em char *data
+argument is an opaque pointer for use by the callback function.  The
+.Pa foreach
+function should return non-zero when it no longer wishes to process
+key-value pairs, at which time
+.Fn yp_all
+returns a value of 0, and is called with the following arguments:
+.Pp
+.Bd -literal -offset indent
+int foreach (
+	int instatus,
+	char *inkey,
+	int inkeylen,
+	char *inval,
+	int invallen,
+	char *indata
+);
+.Ed
+.Pp
+Where:
+.Bl -tag -width "inkey, inval"
+.It Fa instatus
+Holds one of the return status values described in
+.Nm <rpcsvc/yp_prot.h> :
+see
+.Fn ypprot_err
+below for a function that will translate YP protocol errors into a
+.Nm ypclnt
+layer error code as described in
+.Nm <rpcsvc/ypclnt.h> .
+.It Fa inkey, inval
+The key and value arguments are somewhat different here than described
+above.  In this case, the memory pointed to by
+.Fa inkey
+and
+.Fa inval
+is private to
+.Fn yp_all ,
+and is overwritten with each subsequent key-value pair, thus the
+.Pa foreach
+function should do something useful with the contents of that memory during
+each iteration.  If the key-value pairs are not terminated with either
+.Ql \en
+or
+.Ql \e0
+in the map, then they will not be terminated as such when given to the
+.Pa foreach
+function, either.
+.It Fa indata
+This is the contents of the
+.Pa incallback->data
+element of the callback structure.  It is provided as a means to share
+state between the
+.Pa foreach
+function and the user code.  Its use is completely optional: cast it to
+something useful or simply ignore it.
+.El
+.It Fn yp_order
+Returns the order number for a map.
+.It Fn yp_master
+Returns the hostname for the machine on which the master YP server process for
+a map is running.
+.It Fn yperr_string
+Returns a pointer to a null-terminated error string that does not contain a
+.Ql \&.
+or
+.Ql \en .
+.It Fn ypprot_err
+Converts a YP protocol error code to a
+.Nm ypclnt
+error code suitable for
+.Fn yperr_string .
+.El
+.Sh RETURN VALUES
+All functions in the
+.Nm ypclnt
+suite which are of type
+.Em int
+return 0 upon success or one of the following error codes upon failure:
+.Bl -tag -width "YPERR_BADARGS   "
+.It Bq Er YPERR_BADARGS
+The passed arguments to the function are invalid
+.It Bq Er YPERR_BADDB
+The YP map that was polled is defective.
+.It Bq Er YPERR_DOMAIN
+Client process cannot bind to server on this YP domain.
+.It Bq Er YPERR_KEY
+The key passed does not exist.
+.It Bq Er YPERR_MAP
+There is no such map in the server's domain.
+.It Bq Er YPERR_DOM
+The local YP domain is not set.
+.It Bq Er YPERR_NOMORE
+There are no more records in the queried map.
+.It Bq Er YPERR_PMAP
+Cannot communicate with portmap.
+.It Bq Er YPERR_RESRC
+A resource allocation failure occurred.
+.It Bq Er YPERR_RPC
+An RPC failure has occurred.  The domain has been marked unbound.
+.It Bq Er YPERR_VERS
+Client/server version mismatch.  If the server is running version 1
+of the YP protocol,
+.Fn yp_all
+functionality does not exist.
+.It Bq Er YPERR_BIND
+Cannot communicate with
