Wireshark · Wireshark-dev: [Wireshark-dev] how to decode a packet based on the flags in the previous packet.

[qiaoyin_yang@xxxxxxxxxx]

Hello All, 

I am writing a dissector. The captured
traffic has a request packet and a response packet. How the response should
be decoded depends on the information in the previous request packet.  The
request contains a few bytes that I want to read and use it in decoding
the response packet. 

Are there any functions that allow me
to do so? Can anybody please show me these functions or an example. You
help is greatly appreciated!

Thanks!
