Yup.
I tried the suggestions made so far and it never gets to:
printf(" >>> ERRNO %i\n", errno);
I would expect that on a disconnect (I use putty in telnet or raw
mode) it would return -1 whether it is doing MSG_PEEK or an actual
retrieval. No luck.
Nope (http://www.opengroup.org/onlinepubs/7990989775/xns/recv.html):
"If no messages are available to be received and the peer has performed an
orderly shutdown, recv() returns 0."
I think that's what you're missing.
