Well, I'm not sure about UDP sockets, but for TCP sockets it should cancel
read operation the same way as if remote end had closed connection, I
believe. Though the socket won't be useful for reading after that anyway.

Alternate approach to your problem could be to configure receive timeout
for the socket, like this:

  setsockopt(s, SOL_SOCKET, SO_RCVTIMEO, &tv, len);
