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.
