According to the man page, it's Linux-specific.

It's not quite the same thing, anyway. What I had in
mind was attaching the handler itself directly to the
file descriptor, rather than going through a signal
number. That way, different piece of code can use the
mechanism independently on different file descriptors
without having to coordinate over sharing a signal
handler.
