7 Gnulib module: fchownat
9 Portability problems fixed by Gnulib:
12 This function is missing on some platforms:
13 glibc 2.3.6, Mac OS X 10.5, FreeBSD 6.0, NetBSD 5.0, OpenBSD 3.8, Minix 3.1.8,
14 AIX 5.1, HP-UX 11, IRIX 6.5, Cygwin 1.5.x, mingw, MSVC 14.
15 But the replacement function is not safe to be used in libraries and
16 is not multithread-safe. Also, the replacement may fail to change
17 symlinks if @code{lchown} is unsupported, or fail altogether if
18 @code{chown} is unsupported.
20 This function is declared in @code{<sys/stat.h>}, not in @code{<unistd.h>},
24 Some platforms fail to detect trailing slash on non-directories, as in
25 @code{fchown(dir,"link-to-file/",uid,gid,flag)}:
28 Some platforms mistakenly dereference symlinks when using
29 @code{AT_SYMLINK_NOFOLLOW}:
32 This function does not fail for an empty filename on some platforms:
33 Linux with glibc < 2.11.
