Return Table in StoredProceure/Function

How can I return table in Stored Procedure ? I can do it in function but I have inout parameters.So I can not create in function. What can I do this case ?

I guess,It should be like for function :

CREATE or REPLACE FUNCTION public."test" (INOUT "x" integer, INOUT "y" text)

RETURNS TABLE  (
"id" integer,
"filesize" character varying(36)
)
AS $$BEGIN
RETURN QUERY
SELECT * FROM    public."tbl_employees" ;

END;
$$ LANGUAGE plpgsql;

Thanks.
