It works, thanks !

I've got 2 more questions (sorry):

 - Clients has a name returned by dbus_g_method_get_sender. But how
clients can get his name ? My idea is to register a new object for each
client with path "/org/blah/<client's name>". But the client has to know
his name to know the path. Is it possible ? Or should I register an
object with a method like "GetObjectPath" which returns the path of the
object registered for the client calling this method ?

 - Another question: Is it possible to have methods with valist in args
or with the printf syntax. for example func(char *format, ...); ?

Thanks,

Xavier Claessens.
