* Show the sign for NaN as per POSIX; from Elliott Hughes.daniel2014-12-212-8/+6

* C99 says setvbuf() returns non-zero, not EOF. Also, POSIX documentsmillert2014-11-252-10/+37
| | | | | that it returns an error for invalid mode which matches our behavior. OK jmc@ deraadt@

* Reduce instances of `` '' in manuals.bentley2014-11-152-7/+12
| | | | | | | | | | | | troff displays these as typographic quotes, but nroff implementations almost always print them literally, which rarely has the intended effect with modern fonts, even in stock xterm. These uses of `` '' can be replaced either with more semantic alternatives or with Dq, which prints typographic quotes in a UTF-8 locale (but will automatically fall back to `` '' in an ASCII locale). improvements and ok schwarze@
* explicitly clarify that reading also stops after size-1 bytestedu2014-11-041-3/+5

* Use "const char tempchars[]" instead of "const char *tempchars".millert2014-10-311-2/+2
| | | | | Since tempchars is never reassigned there's no need to indirect through a pointer. Still getting used to this newfangled C89.
* The open flags param to mkostemps() should be "flags" not "oflags"millert2014-10-261-3/+3
| | | | for consistency with the rest of the manual.
* Fix bounds check for newlen without relying on unspecified behavior.millert2014-10-161-4/+3

* Add additional userland interfaces for setting close-on-exec on fdsguenther2014-08-317-63/+231
| | | | | | | | | | | | | when creating them: mkostemp(), mkostemps(), the 'e' mode letter for fopen(), freopen(), fdopen(), and popen(). The close-on-exec flag will be cleared by the action created by posix_spawn_file_actions_adddup2(). Also, add support for the C11 'x' mode letter for fopen() and freopen(), setting O_EXCL when possibly creating files. Note: this requires kernel support for pipe2() and dup3()! ok millert@

| | | | | | | arc4random_buf() to avoid lots of arc4random() calls with a getpid() syscall for each one. We fetch 32 bytes of random data at a time which can handle up to 16 Xs. 16 Xs should be enough for anyone. Requested and OK deraadt@
