Hi,
 
I am trying to figure out how wireshark actually does teh dissection of a 
packet. I have a packet and I know the protocol, but do not have a parser for 
it. I would like to be able to give the packet to wireshark and have wireshark 
parse it then read the values back form the appropriate structure.
 
I have been looking a the code and do not see where wireshark a determines what 
the protocol is and which specific dissector to call. I have been able to find 
out where it determines which file type the input file is. I have traced the 
code into a routine called call_dissector_through_handle in packet.c. This 
appears to call the specific dissector through dissector_handle funtion 
pointer. I cannot find where the dissector_handle is set.
 
Am I on the right track? Any guidance would be appreciated.
 
thanks,
 
Tim
