Socket Question (was Re: Socket Tutorial)

[Rayan Zachariassen]

Speaking of sockets, why doesn't SIGIO seem to work on a bound and listened-to
but not accepted file descriptor?  Assume the FASYNC flag is set and the
notified-pid is correct.  Did I do something else wrong?  Would SIGPOLL work
in that situation if the networking was streams-based instead of 4.3 code ?
Yes, select would work, but I'd like an async (non-polled) notification that
someone is trying to talk to me.
