Function Documentation

void QEQueue_postLIFO	(	QEQueue *	me,
		QEvent const *	e
	)

"raw" thread-safe QF event queue implementation for the Last-In-First-Out (LIFO) event posting.

Note:

The LIFO policy should be used only with great caution because it alters order of events in the queue.

The function raises an assertion if the native QF queue becomes full and cannot accept the event. You can call this function from any task context or ISR context. Please note that this function uses internally a critical section.
