61 * @short_description: Helper for accepting connections
64 * #GDBusServer is a helper for listening to and accepting D-Bus
65 * connections. This can be used to create a new D-Bus server, allowing two
66 * peers to use the D-Bus protocol for their own specialized communication.
67 * A server instance provided in this way will not perform message routing or
68 * implement the org.freedesktop.DBus interface.
70 * To just export an object on a well-known name on a message bus, such as the
71 * session or system bus, you should instead use g_bus_own_name().
73 * An example of peer-to-peer communication with G-DBus can be found
74 * in [gdbus-example-peer.c](https://git.gnome.org/browse/glib/tree/gio/tests/gdbus-example-peer.c).
80 * The #GDBusServer structure contains only private data and
81 * should only be accessed using the provided API.

399 * If you want to accept the connection, take a reference to the
400 * @connection object and return %TRUE. When you are done with the
401 * connection call g_dbus_connection_close() and give up your
402 * reference. Note that the other peer may disconnect at any time -
403 * a typical thing to do when accepting a connection is to listen to
404 * the #GDBusConnection::closed signal.
406 * If #GDBusServer:flags contains %G_DBUS_SERVER_FLAGS_RUN_IN_THREAD

409 * [thread-default main context][g-main-context-push-thread-default]
410 * of the thread that @server was constructed in.
412 * You are guaranteed that signal handlers for this signal runs
413 * before incoming messages on @connection are processed. This means
414 * that it's suitable to call g_dbus_connection_register_object() or
415 * similar from the signal handler.
