void scheduler_interrupt

(

void

)

this function is called from a timer interruption. If an event has to be scheduled, it will execute the fonction (IRQ are allowed during the execution of the function). This interruption can be interrupted by itself too, in this case only events with a higher priority can be scheduled.

We assume that this function is called from a SIGNAL(), with global interrupt flag disabled --> that's why we can use cli() and sei() instead of IRQ_LOCK(flags).
