41*fcf3ce44SJohn Forte  * Note: Even though we take various arguments in within the API,
42*fcf3ce44SJohn Forte  * we don't actually filter anything, since sys-even is either on
43*fcf3ce44SJohn Forte  * or off.  The idea is that the actual Listener themselves will perform
44*fcf3ce44SJohn Forte  * a final filter pass, so why do the work twice.  If we were going to
45*fcf3ce44SJohn Forte  * use proprietary IOCTLs or some other event plumbing that allowed filtering,
46*fcf3ce44SJohn Forte  * we could use the passed in arguments to do useful work.  In short,
47*fcf3ce44SJohn Forte  * once turned on, we send events of a given type and rely on
48*fcf3ce44SJohn Forte  * someone downstream to filter.
