RTEMS C User's Guide
The final mechanism for altering the RTEMS scheduling
algorithm is called manual round-robin. Manual round-robin is
invoked by using the rtems_task_wake_after
directive with a time interval of RTEMS_YIELD_PROCESSOR.
This allows a task to give up the
processor and be immediately returned to the ready chain at the
end of its priority group. If no other tasks of the same
priority are ready to run, then the task does not lose control
of the processor.
