Making dig calls in GPG code

Hi all,

Is there a documented way of making dig (dnsutils) calls from within
GPG? Or a standard means to run a shell command and parse its output? I
looked at exec_write() call but its usage wasn't entirely clear after I
read its code because of fork+exec+pipe at play and the pipe reading
from stdin.

Suggestions welcome!

Thanks and Regards,
