AcceptConnection
The AcceptConnection service accepts a TCP connection request from a
remote destination. Before calling AcceptConnection, call CreateSocket
and specify the local port number that will accept the connection. When
AcceptConnection completes, it returns a socket instance that you use for
sending and receiving data on the newly-created connection.
The AcceptConnection service is not valid for UDP sockets.
