Re: Passing data from Plugin dissector to a standard wireshark dissector (i.e. TCP)

a while ago, I added dissection of DVB-CI messages that contain a tcp or
udp part. Have a look at epan/dissectors/packet-dvbci.c. When the
connection is opened, I call store_lsc_msg_dissector() and try to find
the matching dissector for the selected tcp (or udp) port.
Later in dissect_dvbci_payload_lsc(), case
T_COMMS_SEND_LAST..., I call the tcp dissector using call_dissector()
and pass the message tvb as a parameter.

Is this similar to your task?

Regards,
