Hi,
How does your application get called from the network stack?
Wireshark works in a similar way so the answer depends on what your protocol
run:
Ethernet ATM FR TCP UDP SCTP....

Ämne: Re: [Wireshark-dev] packet parsing question
Okay. I did a quick read through the README.developers doc and didn't see
anything that looked like it applied. I also took a look at the
README.design and a couple of other README docs. I have been looking through
code, but I am kind of stuck right now. I guess I was looking for an
overview of the flow. I thought that might help "unstick" me.
Am I missing something or is this all there is? I do not think I have a
"conversation" as described in the README.developer doc. What I have is a
packet that I know the protocol and simply want wireshark to dissect it. Is
it possible for me to have wireshark easily do this?
thanks,

You want to read doc/README.developer from the src tree.
