Don't know what a subdissector does, but ill explain more what im doing. Taking the raw data in my custom dissector, sending it to a dll that will act like a proxy. Sends the data to another lib which sends back a message object to the proxy. Then that object is send to a decoder lib which will allow me to pick out parts of the message that i want using the functions in the decoder lib.
the first lib takes a buffer as parameter and i was wondering how i could pass the data from the dissector to the proxy to the lib. So if thats a subdissector...then yes. What does tvb_new_subset(...) do? I'm new to wireshark development.
Thanks,
Greg

Like a subdissector ?
Look at tcp_dissect_pdus (into packet-tcp.c) :
next_tvb = tvb_new_subset(tvb, offset, length, plen);

The way that i think would be best would be to create a tvbuff and pass it to the dll however, i'm unsure of how to create the new tvbuff with just the one packet of data. I read epan/tvbuff.h and tvbuff.c but i dont quite understand. Any help would be appreciated, or if you have a better idea of how to do this let me know.
