openat - GNU Gnulib

Gnulib module: openat

Portability problems fixed by Gnulib:

This function is missing on some platforms: glibc 2.3.6, Mac OS X 10.5, FreeBSD 6.0, NetBSD 5.0, OpenBSD 3.8, Minix 3.1.8, AIX 5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1, Cygwin 1.5.x, mingw, MSVC 9, Interix 3.5, BeOS. But the replacement function is not safe to be used in libraries and is not multithread-safe.
On platforms where off_t is a 32-bit type, open may not work correctly with files larger than 2 GB. (Cf. AC_SYS_LARGEFILE.)
This function does not fail when the file name argument ends in a slash and (without the slash) names a nonexistent file or a file that is not a directory, on some platforms: Solaris 9.
