Hi,
The below works fine, cheers.
The below stops all further connections but, when my program initialises I
do the below:
WHen I exit the thread, my previous email, things work, but I want to stop
all further connections,then restart them later. As the thread is now
exited, I now have to closethe original socket below. But do I unbind (if
exists) the below, then stop listen(..) . If I do this, how do I do it? and
how would I restart it again.
Regards
Neil

AfxMessageBox(tmp);
return false;
}
if (listen(m_Connection, qlen) == SOCKET_ERROR)

AfxMessageBox(tmp);

Subject: RE: [msvc] breaking out from an event.
I have an application where I want to break out an event, and
exit the thread. I have the following:
WSAEVENT hEvent = WSA_INVALID_EVENT;
hEvent = WSACreateEvent();
::WSAEventSelect(CSock.m_Connection, hEvent, FD_ACCEPT);
but at any point within the application I want to break the thread,
and stop any other connections, then restart the thread again at
any time.
From MSDN on WSAEventSelect():
"Closing a socket with closesocket also cancels the association and
selection of network events specified in WSAEventSelect for the socket.
The
application, however, still must call WSACloseEvent to explicitly close
the
event object and free any resources."
It seems you can simply close the socket, then call WSACloseEvent(), and
it
should be OK to end the thread?
You can call ::WSAEventSelect(CSock.m_Connection, hEvent, 0) first, if
that
make it seem less like pulling the power cord out {;v)
Of course, if you have started waiting on that event, then I guess you
should use WSASetEvent() to set it to signalled (thus ending the wait),
and
carefully check the result from the Wait call to find out that it was
cancelled rather than because you had an accept...
