Creating a PL/pgSQL function that returns multiple out parameters and refcursor

Ho do I create a PL/pgSQL function that returns multiple out parameters and a refcursor. Something like this:

create function myfunction(p_cursor out refcursor, p_code out varchar, p_message out varchar) returns record as $$

  begin

    open p_cursor is select * from table;

    p_code := 'OK';

    p_message := 'message';

    return ???

  end;

$$ language plpgsql;
