Function Documentation

Evt_t event_last_signaled_get

(

void

)

Gets the last signaled event

Returns

Last signaled event

Remarks

Usage:
Used when waiting for multiple events, to find out which event was signaled.

event_wait_multiple(0, event1, event2);
Evt_t lastEvt = event_last_signaled_get();
if ( lastEvt == event1 ) {
  ...
}
