If you're using the evconnlistener code to accept client connections,
you get that information passed to you in the callback when a client
connects.

If you're using accept(), then as other people have noted, you can
pass it a sockaddr_in (or sockaddr_storage, or whatever) to accept()
to find out the address.

If you just have an fd, you can call getpeername() on that fd to find
out the address on the other side.
