* an D-Bus client, it is often easier to use the g_bus_own_name(),
* g_bus_watch_name() or g_dbus_proxy_new_for_bus() APIs.
*
* Most of the ways to obtain a #GDBusConnection automatically initialize it
* (i.e. connect to D-Bus): for instance, g_dbus_connection_new() and
* g_bus_get(), and the synchronous versions of those methods, give you an
* initialized connection. Language bindings for GIO should use
* g_initable_new() or g_async_initable_new(), which also initialize the
* connection.
*
* If you construct an uninitialized #GDBusConnection, such as via
* g_object_new(), you must initialize it via g_initable_init() or
* g_async_initable_init() before using its methods or properties. Calling
* methods or accessing properties on a #GDBusConnection that has not completed
* initialization successfully is considered to be invalid, and leads to
* undefined behaviour. In particular, if initialization fails with a #GError,
* the only valid thing you can do with that #GDBusConnection is to free it
* with g_object_unref().
