@node symlinkat
@section @code{symlinkat}
@findex symlinkat
POSIX specification:@* @url{http://www.opengroup.org/onlinepubs/9699919799/functions/symlinkat.html}
Gnulib module: symlinkat
Portability problems fixed by Gnulib:
@itemize
@item
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, Solaris 10, Cygwin 1.5.x, mingw, MSVC 14, Android 4.4.
But the replacement function is not safe to be used in libraries and is not multithread-safe.
@item
Some platforms declare this function in @code{stdio.h} instead of
@code{unistd.h}:
Cygwin 1.7.1.
@item
On some systems, @code{symlinkat(value, fd, "name/")} mistakenly creates a
symlink:
AIX 7.1.
@end itemize
Portability problems not fixed by Gnulib:
@itemize
@item
This function always fails with @samp{ENOSYS} on platforms that don't
support symlinks:
mingw, MSVC 14.
