* Implement getdelim(3) and getline(3).fgsch2012-03-214-3/+332
| | | | | | | | | Prompted in a mail to tech@ by Jan Klemkow (j-dot-klemkow-at-wemelug-dot-de) but this is based on NetBSD's implementation instead with some tweaks by me. Further improvements would happen in tree. ok millert@; discussed with many others ports cleanup by naddy@, sthen@. Antti Harri, Gonzalo L. R. and myself.
* Credit Keith Sklower and 2BSD for the first implementation of read-writeschwarze2012-01-221-2/+7

* Add support for C99 %ls, %lc, and %l[ format directives to scanf(3).stsp2012-01-183-9/+210
| | | | | | Based on code from FreeBSD. Tested by myself (full release/install cycle on i386 and sparc64) and ajacoutot. Man page help from jmc.
* Document early history of a few functions specifically mentioned in 2BSDschwarze2012-01-152-4/+41

* make -column lists pretty again;jmc2011-09-033-77/+77
| | | | | | | | | | specifically, rewrite them to permit some markup in the column headers, and use "Ta" instead of literal tabs; mandoc does not currently match groff 100%, but a mandoc fix may be some time off, and we've gone enough releases with poorly formatting column lists. in some cases i have rewritten the lists as -tag, where -column made little sense.

* from Tim van der Molen:jmc2011-07-051-5/+12
| | | | | | | | | | | - State that ftell() and ftello() return -1 on error rather than just a non-zero value. The latter is not specific enough, because these functions can also return non-zero on success. - For clarity and search-friendliness, don't refer to fgetpos() and fsetpos() as "the others", but mention them by name. ok millert otto

| | | | | | | and llib-lwrap.ln databases; so that the lint features doing format strings checks are enabled by default. Looks good to millert@.

* Various improvements, mainly regarding ERRORS.schwarze2010-03-221-40/+39
| | | | | | | | | | | | | * Document EINVAL and EEXIST. * Neither mkstemp nor mkdtemp use lstat, but mktemp does. * Documenting ENOTDIR is useless, it is documented in lstat(2), mkdir(2) and open(2), and it's just one thing out of several that could go wrong. * Refer to lstat(2) instead of stat(2), which is actually used here. * State that two of these functions are standardized in the XPG. * Move the sentence about mkdtemp and mkstemps to the new STANDARDS section. * Get rid of the ugly ".So Li X Sc Ns s", just use "Xs" (suggested by jmc@). tweaks and ok jmc@ millert@

| | | | | | | | | | | | | internally when and where required. Macros in <stdio.h> are updated to automatically call the underlying functions when the process is threaded to obtain the necessary locking. A private mutex is added to protect __sglue, the internal list of FILE handles, and another to protect the one-time initialization. Some routines in libc that use getc() change to use getc_unlocked() as they're either protected by their own lock or aren't thread-safe routines anyway. committing on behalf of and okay guenther@ now that we have install media space available.
