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 $$
BEGINRETURN QUERYSELECT * FROM public."tbl_employees" ;
END;$$ LANGUAGE plpgsql;

Thanks.
