symlinkat (GNU Gnulib)

Gnulib module: symlinkat

Portability problems fixed by Gnulib:

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, 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.
Some platforms declare this function in stdio.h instead of unistd.h: Cygwin 1.7.1.
On some systems, symlinkat(value, fd, "name/") mistakenly creates a symlink: macOS 14, AIX 7.1.

Portability problems not fixed by Gnulib:

This function always fails with ‘ENOSYS’ on platforms that don’t support symlinks: mingw, MSVC 14.
