I'd suggest writing a suitable handler script, to forward these traps
to your custom application,
and registering this using "traphandle".  (See snmptrapd.conf(5)).

If your application can read traps from standard input (in the defined
format), then this could even invoke your application directly.
Otherwise, you'd need to have a suitable interface script.

Another possibility would be to write an equivalent internal trap
handler to pass these traps on to your application (using whatever API
is most suitable).   There's less documentation on how to do this, and
it would require adding code to snmptrapd and recompiling - but it
might prove more efficient in the long run.

Either use a 'traphandle' script, or write an internal trap handler.
See forward_handler() and
parse_forward() (both in apps/snmptrapd_handlers.c) for an example of
this latter approach.
