[Telepathy] [SOS!!]how to get group members?

[孟倩倩]

hi, everyone:

     I have a problem when I try to get group members of contactlist. Now I
can create account and have already got the connection interface and can
list channels of the connection, also can get channel
interface--org.freedesktop.Telepathy.Channel.Type.ContactList, but when I
try to get the  members of the contacelist, I don't know how to thansfer the
parameter--DBusGProxy *proxy?

     For implementations of the interface
org.freedesktop.Telepathy.channel.type.contacetlist must also implement
org.freedesktop.Telepathy.channel and
org.freedesktop.Telepathy.channel.interface.group.
I try to request channel list by the interface --
org.freedesktop.Telepathy.Channel.Type.ContactList, using the TpConn which I
already got, it generates "Segmentation fault", I don't know why, please
help me, thank you.

     some source and result as follow:


 1.mc = mission_control_new ( tp_get_bus() );
 2.tp_cm = mission_control_get_connection(mc, account, &new_error);
//account I have already create correctly
 3.tp_conn_get_status(DBUS_G_PROXY(tp_cm), &status, &new_error)---//the
status is connected
 4.tp_conn_request_handles(DBUS_G_PROXY(tp_cm), TP_HANDLE_TYPE_CONTACT,
hdl_names, &hdl_list, &new_error)//hdl_list as follow:
                                       guint i = 0;
                                       for ( ; i < hdl_list->len; i++ ) {
                                            guint handler =
g_array_index(hdl_list, guint, i);
                                            g_debug("handler_name: %s
handler: %d", hdl_names[i], handler);

6.Then I try to get members
    gchar          *object_path;
    const gchar    *bus_name;
    TpChan         *new_chan;
    if (!tp_conn_request_channel (DBUS_G_PROXY (tp_cm),
                      TP_IFACE_CHANNEL_TYPE_CONTACT_LIST,
                      TP_HANDLE_TYPE_GROUP,
                      handle_test,
                      FALSE,
                      &object_path,
                      &new_error)) {
        g_debug ("Couldn't request channel: %s",
                  new_error ? new_error->message : "No error given");
        g_clear_error (&new_error);
        g_object_unref (mc);
        g_object_unref (tp_cm);
        return;
    }

    bus_name = dbus_g_proxy_get_bus_name (DBUS_G_PROXY (tp_cm));
    new_chan = tp_chan_new (tp_get_bus (),
                bus_name,
                object_path,
                TP_IFACE_CHANNEL_TYPE_CONTACT_LIST,
                TP_HANDLE_TYPE_GROUP,
                handle);//when I use handle 0, the result is "Segmentation
fault"
                           when I use handle 3, the result is "Couldn't
request channel: invalid handle 3"


   GArray *member_list = NULL;
   tp_chan_iface_group_get_members (DBUS_G_PROXY(new_chan),
                                        &member_list,
