public bool get_contact_list_sync (string query, Queue out_contacts, Cancellable? cancellable = null) throws Error
Obtains a set of Contact instances which satisfy the criteria
specified in query, and deposits them in out_contacts.
The returned Contact instances are referenced for thread-safety and must be unreferenced with unref when finished with them.
If an error occurs, the function will set throws and return false. Note that an empty result set does not necessarily imply an error.
