- // Socket manager class for Win32.
- // Passed a network::SocketListener and a network::SocketServer when
- // constructed. Uses WSAAsyncSelect to get notifications of network
- // connection attempts. When an incoming connection is received,
- // the manager will call network::SocketServer::addClient(). If
- // addClient returns true then the manager registers interest in
- // network events on that socket, and calls
- // network::SocketServer::processSocketEvent().
