correct.

snmp++ does not use an internal thread, so it's up to the user to call 
these functions when he thinks it's the right time to call one of them 
and a suitable timeout value should be passed.

SNMPProcessPendingEvents() immediately returns if nothing is to do. You 
can use SNMPProcessEvents(1000), which will sleep up to 1000 ms.
