Listen - WinSock

Hi!

I am just trying out few options with Sockets... I was reading the MSDN for the listen function and found the following lines....

If there are no available socket descriptors, listen attempts to continue to function. If descriptors become available, a later call to listen or accept will refill the queue to the current or most recent backlog, if possible, and resume listening for incoming connections.

If listen is called on an already listening socket, it will return success without changing the backlog. Setting the backlog to 0 in a subsequent call to listen on a listening socket is not considered a proper reset, especially if there are connections on the socket.

Can anyone elaborate on the same lines

Does it implies that I can have multiple threads listening on the same socket if that is the case.. how will the server be able to isolate transactions for client requests

Sorry if i sound too stupid but I was unable to decode these lines...

Regards,
