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.
