Summary

Pulses the Event object.

Pascal

 public function Pulse: Boolean;

Return Value

If the function succeeds it returns True, otherwise it returns False. In the latter case you can call GetLastError to get extended error information.

Description

Pulse sets the Event to the signaled state and back to nonsignaled in one single operation releasing the appropriate waiting threads in between. For a manual-reset event, all waiting threads are released before returning the Event to the nonsignaled state. For an auto-reset event, only one waiting thread is released. If no threads are waiting the function merely resets the Event to the nonsignaled state.
