title: dbus c: what bindings (gdbus?) and client/server simple example
body: <p>I would like to use dbus for communication between applications (actually I'm using a localhost socket).
  I'm searching for a very basic (but complete/compilable) working example, so googleing around I found that the low level api is not to use because it is better to use bindings, dbus-glib bindings have some documentation but are also not to use because now there's the new gdbus (dbus integrated in glib) since version 2.26.
  about gdbus except for the api <a href="http://developer.gnome.org/gio/stable/gdbus-convenience.html" rel="nofollow">http://developer.gnome.org/gio/stable/gdbus-convenience.html</a> I cannot find any mini tutorial/minimal working example.
  Can anybody help me out with this?
  Thanks.</p>
