Обсуждение: execute query from inside C function

I've googled the docs but I can't seem to make a link as to how to execute database queries from inside a C function.
I'mused to having a PGconn and using the API around that, but how do I do that from inside a C function (and a bit
lateron, a language handler?) 

Thanks

Yep just found it. I obviously didn't google hard enough.

Thanks
