If you are handling this from within the master SNMP agent,
then you could invoke the config-handling code using a
suitably constructed string - i.e the equivalent of what you
would otherwise have read in from the config file.
Probably something like
sprintf( mybuf, "trapsink %s", newdest )
snmp_config_when( mybuf, NORMAL_CONFIG );
(untested!)
Otherwise if you're working from a subagent or some other application,
then you''ll probably be looking at manipulating the snmpNotifyTable,
snmpTargetAddrTable and snmpTargetParamsTable directly,
using SET commands.
Try walking these tables to see what entries get installed by
the "trapsink" (and similar) directives under the normal agent.
Then use "snmpset" to reproduce these manually.
Once you've identified the appropriate SET varbinds to use,
then you can hardcode these into your subagent/application.
