Anticipating the default handler

Looking at the example in the tutorial,

     http://www.net-snmp.org/dev/agent/scalar__int_8c-example.html

I wrote the test at the end of this email.

My problem is that my handler apparently gets called after the default
handler, so if I want to manipulate the string that the agent will
return, my manipulation happens after the default handler returns the
value.

How can I prevent this?

Thanks,

    netsnmp_register_read_only_int_instance("my example int variable",
                                            my_registration_oid,

                                            &jordi_int, &jordi_handler);

 Sample output:

 jordi@clio:~/snmp$ snmpget localhost netSnmpExampleInteger.0
 NET-SNMP-EXAMPLES-MIB::netSnmpExampleInteger.0 = INTEGER: 6969
 jordi@clio:~/snmp$ snmpget localhost netSnmpExampleInteger.0
 NET-SNMP-EXAMPLES-MIB::netSnmpExampleInteger.0 = INTEGER: 42

 Want 42 to always be the answer, not 6969.
