Writing SQL functions in Postgres

Hi,

I want to write an SQL function in postgres that returns
row as a result.

The problem is the select statement inside the funtion has
a two table join. So I dont know what to put after SETOF

CREATE FUNCTION dummy()
RETURNS SETOF ?????
AS 'select a.name,b.cc
from tblusers a,
tbldocs b
where a.name=b.name'
LANGUAGE 'SQL';

SETOF tblusers -- doesnt work
ERROR: function declared to return type tblusers does not retrieve
(tblusers.*)

neither does SETOF tbldocs

SETOF tblusers,tbldocs wont work either.

Anyone was able to returns a row that is a result of few table joins
inside the
function???
