[Click] help

[科进 舒]

hi,
     Nowadays I am trying to handle netflows with click.I think it's really useful and helpful when I caputure or classify the packets but when I want to handle the packets more precisely,it's hard to do that.
     As I see from the web,click stores packets in a single flat array of bytes.And now I want to parse the packets and then store every part of packets separately.
     Now my question is I can parse the packets from the array,but I don't know how to store them,particularly,the data.How to store and handle the binary data?
     Besides,is there a packet structure that I can use to get every part of the packet easily,like src ip,dst ip,src port,dst port,protocol and so on ?
     Best wishes and waiting for your responses!
     Thank you!
                                                                           Sincerely yours,
                                                                                Aaron
