POSIX specification: http://www.opengroup.org/onlinepubs/9699919799/functions/faccessat.html

Gnulib module: faccessat

Portability problems fixed by Gnulib:

  * This function is missing on some platforms: glibc 2.3.6, MacOS X 10.3, FreeBSD 6.0, NetBSD 3.0, OpenBSD 3.8, AIX 5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1, Solaris 10, Cygwin 1.5.x, mingw, Interix 3.5, BeOS. However, the replacement does not always take into account ACLs.

Portability problems not fixed by Gnulib:

  * There is an inherent race between calling this function and performing some action based on the results; you should think twice before trusting this function in a set-uid or set-gid program.
