On Mon, Dec 14, 2009 at 10:52 AM, Nicola Michael Gutberlet You generally have to do a read on the socket to reliably detect when the other side has closed (or crashed).

And a write, too, or else use TCP keepalives.

Unfortunately, write isn't reliable since it will always succeed until you fill up your send buffer. Jon
