The utility 'rndc status' will return the full path of the configuration 
file:
   rndc status | grep "configuration file:"

And the utility 'named-checkconf -px configfile' will print out the 
configuration in canonical form, from which you could grab anything you 
like.

But if what you want isn't in the configuration file (e.g. passed as a 
command-line parameter, or compiled in), then named-checkconf isn't 
going to help. To learn those, I think you'll need to query the 
operating system for information about the specif process. I'd be 
looking at pgrep and ps, but there's probably better ways to do it.
