Thread: How to close an open port with WindowsSockets

The socket will not close if there is data incomming or it is 'held' open by the server.

Try this, before calling to close, to slam the socket shut without waiting for it to clean up.

Code:

LINGER    DontLinger;

DontLinger.l_onoff=1;
DontLinger.l_linger=0;

setsockopt(Socket, SOL_SOCKET, SO_LINGER  ,(char*)&DontLinger ,sizeof(LINGER) );

We aren't coding a firewall, he is gonna use it for sharing, like Napster, the prob was, that the port wasn't closed -> we gonna check it.

Thank's for the help (-> but is there a function to close directly the port, when the tool is going to be closed).

I think this information will help me too, for coding a Apache module for this sharing prog.

You mean

if(closesocket(SOCKET)==SOCKET_ERROR)
iError=WSAGetLastError();
