How can I see the contents in a Ref Cursor

Question

I have this code:
CREATE OR REPLACE PACKAGE APOD_LOG.APOD_C3_LOG_API_PKG
AUTHID CURRENT_USER
AS
type rc is ref cursor;
PROCEDURE Fetch_Log_Spec
in_LOCAL_IP_VALUE IN BINARY_INTEGER,
out_RESULT_SET OUT rc
END APOD_C3_LOG_API_PKG;
CREATE OR REPLACE PACKAGE BODY APOD_LOG.APOD_C3_LOG_API_PKG
AS
PROCEDURE Fetch_Log_Spec
in_LOCAL_IP_VALUE IN BINARY_INTEGER,
out_RESULT_SET OUT rc
IS
BEGIN
DBMS_APPLICATION_INFO.set_module(module_name => 'APOD_LOG.API_PKG',action_name => 'Fetch_Log_Spec');
DBMS_APPLICATION_INFO.set_client_info(client_info => 'Calling with in_LOCAL_IP_VALUE = ' ||to_char(in_LOCAL_IP_VALUE));
open out_RESULT_SET for
select
in_LOCAL_IP_VALUE as IN_LOCAL_IP_VALUE,
10002 as PORT,
APOD_CORE.UTIL_IP_PKG.IPAddressToIPValue2('''224.168.100.1''') as MULTICAST_IP_VALUE
from
dual
union
select
in_LOCAL_IP_VALUE as IN_LOCAL_IP_VALUE,
10002 as PORT,
APOD_CORE.UTIL_IP_PKG.IPAddressToIPValue2('''224.168.200.1''') as MULTICAST_IP_VALUE
from
dual
union
select
in_LOCAL_IP_VALUE as IN_LOCAL_IP_VALUE,
10002 as PORT,
APOD_CORE.UTIL_IP_PKG.IPAddressToIPValue2('''224.168.100.123''') as MULTICAST_IP_VALUE
from
dual
union
select
in_LOCAL_IP_VALUE as IN_LOCAL_IP_VALUE,
10002 as PORT,
APOD_CORE.UTIL_IP_PKG.IPAddressToIPValue2('''224.168.200.123''') as MULTICAST_IP_VALUE
from
dual;
DBMS_APPLICATION_INFO.set_client_info(client_info => 'Called Fetch_Log_Spec '||to_char(SQL%ROWCOUNT)||' row(s) returned with in_LOCAL_IP_VALUE = '||to_char(in_LOCAL_IP_VALUE) );
END Fetch_Log_Spec;
END APOD_C3_LOG_API_PKG;
And I am trying to test it like this:
DECLARE
IN_LOCAL_IP_VALUE BINARY_INTEGER;
OUT_RESULT_SET APOD_LOG.APOD_C3_LOG_API_PKG.rc;
BEGIN
IN_LOCAL_IP_VALUE := 23374048;
-- OUT_RESULT_SET := NULL; How do I see this
APOD_LOG.APOD_C3_LOG_API_PKG.FETCH_LOG_SPEC ( IN_LOCAL_IP_VALUE, OUT_RESULT_SET );
END;
How can I see the dataset returnd by the OUT_RESULT_SET in SQLPlus or Quest ScriptRunner?

A ref cursor doesn't really contain rows but you can use them to reference a SQL statement that fetches the rows.
