I'm not sure quite what's happening as regards the engineID.
But one thing I (eventually!) noticed about your program:
> This is what I wrote in the program:

If this is a Trap-style PDU that you're sending, then there shouldn't
actually be a response. Traps are unacknowledged.
If you need a response to be returned, you should use SNMP_MSG_INFORM.
I'm also not sure that you can use SNMP_MSG_TRAP with an SNMPv3 session
anyway - that's a v1 trap, so is only valid with SNMPv1.
For SNMPv3 (or SNMPv2c) you should use SNMP_MSG_TRAP2 instead.
If pressed, I'd suspect that the engineID should be a binary value,
rather than an ASCII string. But I'm no SNMPv3 expert (which is why
I didn't really look at this query properly before now).
And it's probably much too late now anyway. Sorry about that.
