void vCoRoutineSchedule( void );

Run a co-routine.

vCoRoutineSchedule() executes the highest priority co-routine that is able to run. The co-routine will execute until it either blocks, yields or is preempted by a task. Co-routines execute cooperatively so one co-routine cannot be preempted by another, but can be preempted by a task.

If an application comprises of both tasks and co-routines then vCoRoutineSchedule should be called from the idle task (in an idle task hook).

Example usage:

// This idle task hook will schedule a co-routine each time it is called.
// The rest of the idle task will execute between co-routine calls.
void vApplicationIdleHook( void )
{
   vCoRoutineSchedule();
}

// Alternatively, if you do not require any other part of the idle task to
// execute, the idle task hook can call vCoRoutineScheduler() within an
// infinite loop.
void vApplicationIdleHook( void )
{
   for( ;; )
   {
       vCoRoutineSchedule();
   }
}
