// -=- SocketManager.h
// 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().
