I will be calling it from a JAVA application using JNI. Not sure how whether or not I run Ethernet affects this situation. I will not be requiring wireshark to access the network at all. I simply have a packet of data from another application that I can convert to whatever C structure/datatype I need to. I would like to be able to pass that "packet" to wireshark to parse and then I will access the wireshark structure to get the parsed values.
As I look through the code I do not think wireshark was created for this, but would like to see if it is possible. It would allow me to reuse the protocol dissectors. I think the dissectors in wireshark have been tested and would simply like to reuse them.
Do this clarify things?
thanks

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.
