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.
|
|
But the replacement function is not safe to be used in libraries and is not multithread-safe.

Some platforms do not allow changing the access bits on symbolic
|
|
links. POSIX states that @code{fchmodat(@dots{},AT_SYMLINK_NOFOLLOW)}
|
|
may fail with @code{EOPNOTSUPP} when called on a symlink, but some
|
|
platforms, as well as the gnulib replacement, fail for any use of
|
|
AT_SYMLINK_NOFOLLOW even if the target was not a symlink:
|
|
glibc, Cygwin.
