MIB callback handler

[Yeo Siow Vic]

hi,   I have built a customised MIB into SNMP agent.   Now I want to customise the the processing of SNMP GET/SET. I register a callback function in netsnmp_register_table_data_set().   The callback function is: int dot11xxxxxxx_handler(netsnmp_mib_handler *handler,                                 netsnmp_handler_registration *reginfo,                                 netsnmp_agent_request_info *reqinfo,                                 netsnmp_request_info *requests) {     /*      * perform anything here that you need to do.  The requests have      * already been processed by the master table_dataset handler, but      * this gives you chance to act on the request in some other way      * if need be.      */   }   How to change this function, so that processing is according to OID? Where can i find example?   Rgds, Siow Vic
