In order to receive traps you should use  snmp++; I have implemented a
snmptrapd which make use of snmp::notify_register()
method to register a collection of traps OIDs I am intereste in to
receive and a collection of trap  senders which I listen
for incomming traps. Once a traps is received  the myCallback method is
invoked to handle it. You can find more inf on the SNMP++
documentation.

myCallback(int reason, Snmp *snmp,
                Pdu &pdu, SnmpTarget &target, void *data)
{
  // handle the received trap pdu here..
}

void
listen(int portNumber)
{
   int status;
   Snmp snmp(status);
   if(status != SNMP_CLASS_SUCCESS) {
        //handle error here
   }

   CNotifyEventQueue::set_listen_port(portNumber);
   status = snmp.notify_register(trapOidCollection, trapSenderCollection,

                                 myCallback, NULL);
   if (status != SNMP_CLASS_SUCCESS) {
         //handle error here
   }
   while (true)
       SNMPProcessEvents();
}
