Is this a standalone application, a separate subagent,
or a module within the main SNMP agent?
How are you sending the traps?

If this is part of the main SNMP agent, then the easiest way
would probably be to call
netsnmp_config("trapsink 10.20.30.40");
That sets up the trap destination, in exactly the same way
as the equivalent line in snmpd.conf would do.
If this is part of a standalone application, then it's up to you
to initialise the netsnmp_session structure used for sending
the trap. So you can configure the appropriate destination
yourself.
If this is part of an AgentX subagent, then it's not really possible.
At least, not if using the 'sent_trap()' style of call. The subagent
simply passes the notification off to the master agent, and it's
up to the master agent where these are sent.
The only sensible approach here would be to send the traps
directly to the required destination. In which case, this is
effectively a standalone application. See the previous case.
