39  * A #GSocketService is an object that represents a service that
40  * is provided to the network or over local sockets.  When a new
41  * connection is made to the service the #GSocketService::incoming
42  * signal is emitted.
43  * 
44  * A #GSocketService is a subclass of #GSocketListener and you need
45  * to add the addresses you want to accept connections on with the
46  * #GSocketListener APIs.
47  * 
48  * There are two options for implementing a network service based on
49  * #GSocketService. The first is to create the service using
50  * g_socket_service_new() and to connect to the #GSocketService::incoming
51  * signal. The second is to subclass #GSocketService and override the
52  * default signal handler implementation.
53  * 
54  * In either case, the handler must immediately return, or else it
55  * will block additional incoming connections from being serviced.
56  * If you are interested in writing connection handlers that contain
57  * blocking code then see #GThreadedSocketService.
58  * 
59  * The socket service runs on the main loop of the
60  * [thread-default context][g-main-context-push-thread-default-context]
61  * of the thread it is created in, and is not
62  * threadsafe in general. However, the calls to start and stop the
63  * service are thread-safe so these can be used from threads that
64  * handle incoming clients.
65  *
