[Telepathy] obtaining handles to contacts to establish a text channel

[harini satyanarayanan]

It worked finally, i guess it was probably a badly organized code or
data structure, i modified it and it worked. this is the working
snippet of the code.



    const gchar  *id = "contact at gmail.com";


    const gchar *contact_ids[] = {id, NULL};


    success = tp_conn_request_handles (DBUS_G_PROXY
(tp_connection),TP_CONN_HANDLE_TYPE_CONTACT,contact_ids, &handles1,
&error1);
    handle1 = g_array_index(handles1, guint, 0);
    g_array_free (handles1, TRUE);

Thanks for all the help!!!! :)

thanks,
harini
