Function Documentation

void QF_tick

(

void const *const

sender

)

Processes all armed time events at every clock tick.

This function must be called periodically from a time-tick ISR or from the highest-priority task so that QF can manage the timeout events.

Note:

The QF_tick() function is not reentrant meaning that it must run to completion before it is called again. Also, QF_tick() assumes that it never will get preempted by a task, which is always the case when it is called from an ISR or the highest-priority task.

this function should be called only via the macro QF_TICK
