Testing for a closed socket

Question

I\'m trying to test for a closed socket that has been gracefully closed by the peer without incurring the latency hit of a double send to induce a SIGPIPE.

Answer 1

(Slightly "off topic", sorry). Perhaps this discussion may be helpful four you. It still doesn't answer to you "FIN" question, but may help you to react in a more easy way to the peer shutdown while your program is sending.
