"Finally"? You mean, the part of the code which is responsible for 
opening the socket, sending the packet, retrying it, etc. etc.? That's a 
fairly uninteresting part of the code, and also it tends to be somewhat 
dependent on the underlying OS and/or network stack. Depending on 
exactly what you're trying to do, you may be more interested in the part 
of the code which "renders" the packet, i.e. converts the internal data 
structures into wire-format.

Also, are you dealing with BIND 8 or BIND 9? These are completely 
different codebases.

Beyond the comments in the source files, include files, etc.? Not that 
I'm aware of. If you find any, please let me know.
