Symbolic links

[fanf]

What happens if you try to create a symlink to a zero-length target, as in ln -s "" foo?

Linux: ENOENT.

Mac OS X 10.4: EINVAL.

FreeBSD: works, and any attempt to resolve the symlink returns ENOENT.

Solaris: works, and the resulting symlink behaves the same as ln -s . foo

A quick strace ln -s "" zzz turns up

symlink("", "zzz")                      = -1 ENOENT (No such file or directory)

so it doesn't look as if glibc is doing anything obviously silly above the syscall level.
