And the link there to "(see Graceful shutdown, linger options, and socket closure for more information)". To assure that all data is sent and received on a connected socket before it is closed, an application should use shutdown to close connection before calling closesocket. For example, to initiate a graceful disconnect: 1)Call WSAAsyncSelect to register for FD_CLOSE notification. 2)Call shutdown with how=SD_SEND. 3)When FD_CLOSE received, call recv until zero returned, or SOCKET_ERROR. 4)Call closesocket.
