glibc/misc/mkstemp.c
Ulrich Drepper 46c3f8cdb4 Update.
2001-02-26  Paul Eggert  <eggert@twinsun.com>

	Modify mkstemp.c and tempname.c so that they can be used by
	GNU applications on non-glibc platforms.

	* misc/mkstemp.c (__GT_FILE): Define to zero if not defined.

	* sysdeps/posix/tempname.c: Include <config.h> if HAVE_CONFIG_H.
	Include <stddef.h>, <stdint.h>, <string.h> only if
	STDC_HEADERS || _LIBC.
	Include <fcntl.h> only if HAVE_FCNTL_H || _LIBC.
	Include <unistd.h> only if HAVE_UNISTD_H || _LIBC.
	Include <sys/time.h> only if HAVE_SYS_TIME_H || _LIBC.
	(__set_errno): Define this macro if <errno.h> doesn't.
	(P_tmpdir, TMP_MAX, __GT_FILE, __GT_BIGFILE, __GT_DIR, __GT_NOCREATE):
	Define these macros if <stdio.h> doesn't.
	(S_ISDIR, S_IRUSR, S_IWUSR, S_IXUSR):
	Define these macros if <sys/stat.h> doesn't.
	Ignore <sys/stat.h> S_ISDIR if STAT_MACROS_BROKEN.
	(stat64, __getpid, __gettimeofday, __mkdir, __open, __open64,
	lxstat64, __xstat64): Define if not _LIBC.
	(struct_stat64): New macro.
	(direxists, __gen_tempname): Use it, to avoid a
	portability problem with Solaris 8.
	(__secure_getenv): Define if ! (HAVE___SECURE_GETENV || _LIBC).
	(__gen_tempname): Invoke gettimeofday only if
	HAVE_GETTIMEOFDAY || _LIBC; otherwise, fall back on plain "time".
	Use portable macros like S_IRUSR | S_IWUSR rather than nonportable
	octal values like 0600.
