print location

[stephen () stephengarrett net]

Hi,

I'm trying to find where in the code tcpdump prints the packet info like source and destination IP addresses.  I need 
to insert some code to make a custom version of tcpdump that will send a message to another program every time tcpdump 
prints a line, and I also need to know if those source and destination IP addresses are stored in a variable somewhere 
and if not, how can I access them.

Any help or direction is greatly appreciated.

Thanks,
Stephen
