Hey All -

Is there any way to natively broadcast an event/signal/message to multiple processes? 

Example: 

Processes A, B, and C all want to know when some Event X has occurred, so they each register themselves in the system 
and block on the arrival of Event X.

At some later point in time, some ISR fires and broadcasts Event X out to the system. Processes A, B, and C all wake up 
and do their own special onEventX() handler stuff...

Is something like that possible with native QNX messaging? 

Thanks!
