Hi,
You'll find an interface between the wiretap library providing input
and the dissection engine in epan/packet.c:dissect_packet(). Here the
packet data is encapsulated in a TVB and presented to the top level
dissector.
Thanks,
Jaap

If I want to understand how the wireshark print the contents of the
packets wireshark just as the table at the bottom in wireshark GUI,which
files should I read. In fact,I just want to find out the array which
save the data of the packet wireshark has captured so that I can do some
work with the data.As http protocol,should I read the files
packet-http.c under the directory wireshark/epan/dissectors or other files?
I have read the epan/packet.c:dissect_packet() .However I am still not
very clear about where the data is.Do you mean the edt->tvb save the
packet data ?
Hi,
Indeed edt->tvb is the object containing your packet data, to be
accessed through its interface functions.
Thanks,
Jaap

Thank you very much. I have found the packet data in edt->tvb.Actually I
have noticed edt->tvb- >real_data get the packet data through the
argument const guchar *pd in dissect_packet() .However I can't find
where dissect_packet() is called.Where pd come from.For http protocol,I
can't find that dissect_packet() is called in
wireshark/epan/dissectors/packet-http.c
