OID comparision in callback handler

[Yeo Siow Vic]

hi,   I have a MIB table, i use mib2c to create the c file. I want to customise the processing of the MIB table. Therefore, i have to compare the OID of eacg incoming request and take action respectively.   How should i compare the OID in callback handler??   i can't figure out.   if (requests->requestvb->name == .......)  /*??? what should be here*/   int dot11PhyTable_handler(netsnmp_mib_handler *handler,                                 netsnmp_handler_registration *reginfo,                                 netsnmp_agent_request_info *reqinfo,                                 netsnmp_request_info *requests) {     u_long * curChannel_cache = NULL;     int channel;   printf("[cb handler] channel %d\n",channel);     /*      * 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.      */   printf("Oid is %s\n", requests->requestvb->name); printf("Oid length is %d\n", (requests->requestvb->name_length));       switch (reqinfo->mode) {         /*          * registering as an instance means we don't need to deal with          * getnext processing, so we don't handle it here at all.          *          * However, since the instance handler already reset the mode          * back to GETNEXT from the faked GET mode, we need to do the          * same thing in both cases.  This should be fixed in future          * versions of net-snmp hopefully.          */     case MODE_GET:     case MODE_GETNEXT:         /*          * return the curren value          */         snmp_set_var_typed_value(requests->requestvb,                                  ASN_INTEGER,                                  (u_char *) &channel,                                  sizeof(channel));         break;       case MODE_SET_ACTION:         /*          * update current value          */         channel = *(requests->requestvb->val.integer); printf("[cb handler] updated channel is %d\n", channel);         break;       default:         break;     }     return SNMP_ERR_NOERROR; }
