9.235 fchownat
POSIX specification:
http://www.opengroup.org/onlinepubs/9699919799/functions/fchownat.html
Gnulib module: fchownat
Portability problems fixed by Gnulib:
- Some platforms fail to detect trailing slash on non-directories, as in
fchown(dir,"link-to-file/",uid,gid,flag)
:
Solaris 9.
- Some platforms mistakenly dereference symlinks when using
AT_SYMLINK_NOFOLLOW
:
Linux kernel 2.6.17.
- This function does not fail for an empty filename on some platforms:
Linux with glibc < 2.11.
- 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. Also, the replacement may fail to change
symlinks if
lchown
is unsupported, or fail altogether if
chown
is unsupported.
