* colon. Ports may be given as decimal numbers or symbolic names (in
* which case an /etc/services lookup is performed).
*
* If no port override is given in @host_and_port then @default_port will be
* used as the port number to connect to.
*
* In general, @host_and_port is expected to be provided by the user (allowing
* them to give the hostname, and a port overide if necessary) and
* @default_port is expected to be provided by the application.
* In the case that an IP address is given, a single connection

/**
* SECTION: gsocketservice
* @title: GSocketService
* @short_description: a high-level object representing a service
* @see_also: #GThreadedSocketService, #GSocketListener.
*
* A #GSocketService is an object that represents a service that is
* provided to the network or over local sockets. When a new
* connection is made to the service the ::incoming signal is emitted.
*
* A #GSocketService is a subclass of #GSocketListener and you need
* to add the addresses you want to accept connections on to the
* with the #GSocketListener APIs.
*
* There are two options for implementing a network service based on
* #GSocketService. The first is to create the service using
* g_socket_service_new() and to connect to the ::incoming signal.
* The second is to subclass #GSocketService and override the default
* signal handler implementation.
*
* In either case, the handler must immediately return, or else it
* will block additional incoming connections from being serviced. If
* you are interested in writing connection handlers that contain
* blocking code then see #GThreadedSocketService.

* The socket service runs on the main loop in the main thread, and is
* not threadsafe in general. However, the calls to start and stop
* the service are threadsafe so these can be used from threads that

* As with #GSocketService, you may connect to ::run, or subclass and
