Re: using pinfo structure to save data after first iteration

[koundinya poluri <koundi.poluri () gmail com>]

Hi guys,

I am not completely familiar with the conversations part of wireshark.I did
go throught the sharkfest ppt by Guy Haaris.Then I realized that i can use
the p_add_proto_data or p_get_proto_data to save data for each packet.I am
not familar with it so I am reading rtp dissectors's code to understand it
better.

As I understand a conversation is created using the port and ip addresses
and then dissectors add their convo_data using the handle(proto_rtp in case
of rtp) then you can get get the conversation using find_conversation.The
link I am missing is how is this conversation related to
p_add/get_proto_data.
So I have a couple of questions hope you dont mind answering them!

1.How is a conversation related to p_add/get_proto_data.
2.where does p_add_proto_data save the data after it is called?

Thanks a lot!
