+# D-Bus Name Watching
+
+Convenience API for watching bus names.
+
+A simple example for watching a name can be found in
+[`gdbus-example-watch-name.c`](https://gitlab.gnome.org/GNOME/glib/-/blob/HEAD/gio/tests/gdbus-example-watch-name.c).
+
+The main API for watching names is:
+ * [func@Gio.bus_watch_name]
+ * [func@Gio.bus_unwatch_name]
