One additional point.
Entries in the zone file are normally of the form:
somealias IN CNAME somecanonicalnameorotheralies
What I would like to achieve is
For zone file example.com entries of the form
[*] IN PNAME [Name of routine that parses [*] and returns somecanonicalnameorotheralias]
Does anyone have idea how this might be achieved or point me to the appropriate source code section(s). My C/C++ skills are somewhat rusty and a helpful start would be apprecaited.
Thanks
