Cursors returned from a package

Question

Ok, I've done this a long time ago but how do I get a package to return a cursor?
Here's my spec...
CREATE OR REPLACE PACKAGE reservationhistory AS
TYPE ResType IS RECORD
               (resid integer,
               status varchar2(2));
PROCEDURE getHistory(i_providerid in integer,
     resdetail in out ResType,
     o_error_code out varchar2);
END reservationhistory;
Here's my attempt at the body...
CREATE OR REPLACE PACKAGE BODY reservationhistory AS
PROCEDURE getHistory(i_providerid in integer,
          resdetail in out ResType,
          o_error_code out varchar2) IS
BEGIN
OPEN resdetail FOR
               select bookingid resid, status, providerid from booking
               where providerid = i_providerid;
          o_error_code := 0;
END getHistory;
END reservationhistory;
But it doesn't like this.
What am I missing???
Thanks,
Todd

Thanks, I tried that and but it still doesn't work. The following code gives me this error:
LINE/COL ERROR
10/9 PLS-00306: wrong number or types of arguments in call to
'RESDETAIL'
10/9 PL/SQL: SQL Statement ignored
Here's the code...
CREATE OR REPLACE PACKAGE reservationhistory AS
TYPE ResType IS ref cursor;
PROCEDURE getHistory(i_providerid in integer,
     resdetail in out ResType,
     o_error_code out varchar2);
END reservationhistory;
CREATE OR REPLACE PACKAGE BODY reservationhistory AS
PROCEDURE getHistory(i_providerid in integer,
          resdetail in out ResType,
          o_error_code out varchar2) IS
BEGIN
OPEN resdetail FOR
               select bookingid resid, status, providerid from booking
               where providerid = i_providerid;
          o_error_code := 0;
END getHistory;
END reservationhistory;
I appreciate your help on this.
