Ok, I used the solution you suggested by using a thread but I have a
problem when referencing the delegated cache:
* I register an handler for a scalar with:
netsnmp_register_scalar(
netsnmp_create_handler_registration("data", data_handler,
data_oid, OID_LENGTH(data_oid),
HANDLER_CAN_RWRITE)
);
* Then in data_handler I crete a delegated cache and spawn the thread:
requests->delegated = ~0;
cache = netsnmp_create_delegated_cache(handler, reginfo, reqinfo, requests,
if (cache == NULL)
goto create_cache;
ret = pthread_create(&tid, NULL, data_delayed_handler, cache);
if (ret < 0)
goto create_thread;
pthread_detach(tid);
* When I check the delegated cache in data_delayed_handler I got NULL!
cache = (netsnmp_delegated_cache *) data;
cache = netsnmp_handler_check_cache(cache);
if (cache == NULL) {
snmp_log(LOG_ERR, "illegal call to return delayed response for \"data\"\n");
return;
}
Where I do wrong?
Thanks in advance,
Rodolfo
