If your select() call returns telling you that there is something readabl=
e (or=20
a QSocketNotifier sends you a signal) and a subsequent read() call return=
s 0=20
bytes, the socket has been closed by the remote end. You can still get a=20
SIG_PIPE of course if the connection closes just before you try to send=20
something.
