You apparently have no understanding at all of how parameters are passed
to and from C-language functions in Postgres :-(. Start here:
http://www.postgresql.org/docs/8.3/static/xfunc-c.html
and note that any situation involving multiple OUT parameters is handled
as returning an anonymous composite type. There are a number of
useful examples in the contrib modules.
