pn_rt_handle = find_dissector("pn_rt);
 
> void proto_reg_handoff_pb(void)
> {
> static gboolean initialized=FALSE;

> if (!initialized) {
  
pn_rt_handle = find_dissector("pn_rt);

> pb_handle = create_dissector_handle(dissect_pb, proto_pb);
> dissector_add("pn_rt.frame_id", 0xffff , pb_handle);
 
initialized = TRUE;
