Reading below I assume you found this out, but just in case, it's sparse but an easy introduction: https://bind9.readthedocs.io/en/latest/chapter4.html#developing-plugins Also, see `lib/ns/include/ns/hooks.h` which contains a way more detailed explanation of plugin internals. > trying to do what I want to do.

If somebody could help there... I'd suggest having a look at `bin/plugins/synthrecord.c`, in particular the function `synthrecord_response` (and its call-sites) which synthesize a record. Not exactly what you want, but it's a good start to grasp how to create/manipulate rdata/rdatalist/rdataset.
