63 * @short_description: Helper for accepting connections
66 * #GDBusServer is a helper for listening to and accepting D-Bus
67 * connections. This can be used to create a new D-Bus server, allowing two
68 * peers to use the D-Bus protocol for their own specialized communication.
69 * A server instance provided in this way will not perform message routing or
70 * implement the org.freedesktop.DBus interface.
72 * To just export an object on a well-known name on a message bus, such as the
73 * session or system bus, you should instead use g_bus_own_name().
75 * <example id="gdbus-peer-to-peer"><title>D-Bus peer-to-peer example</title><programlisting><xi:include xmlns:xi="http://www.w3.org/2001/XInclude" parse="text" href="../../../../gio/tests/gdbus-example-peer.c"><xi:fallback>FIXME: MISSING XINCLUDE CONTENT</xi:fallback></xi:include></programlisting></example>

402 * connection call g_dbus_connection_close() and give up your
403 * reference. Note that the other peer may disconnect at any time -

415 * that it's suitable to call g_dbus_connection_register_object() or
