When a new 40 * connection is made to the service the #GSocketService::incoming 41 * signal is emitted. 42 * 43 * A #GSocketService is a subclass of #GSocketListener and you need 44 * to add the addresses you want to accept connections on with the 45 * #GSocketListener APIs. 46 * 47 * There are two options for implementing a network service based on 48 * #GSocketService. The first is to create the service using 49 * g_socket_service_new() and to connect to the #GSocketService::incoming 50 * signal. The second is to subclass #GSocketService and override the 51 * default signal handler implementation. 52 * 53 * In either case, the handler must immediately return, or else it 54 * will block additional incoming connections from being serviced. 55 * If you are interested in writing connection handlers that contain 56 * blocking code then see #GThreadedSocketService. 57 * 58 * The socket service runs on the main loop of the 59 * [thread-default context][g-main-context-push-thread-default-context] 60 * of the thread it is created in, and is not 61 * threadsafe in general.
