Have a look at 'snmptrapd' - in particular the routines
   netsnmp_add_traphandler()  and
   netsnmp_add_global_traphandler()


These can be used to invoke a specified routine when
either a particular trap arrives (1st form), or *any*
trap arrives (2nd form)

Unfortunately, snmptrapd.conf won't help you here.
That can be used to configure various "standard" trap
handler routines, but not to add new ones.  If you
need to add this extra functionality, you're going
to have to start tweaking the snmptrapd code itself.


Have a look at some of the existing trap handlers
(in 'snmptrapd_handler.c'), and how they are registered
(in 'snmptrapd.c').

Any questions, just ask on the list.
