sched_yield - temporarily pause the current thread in favor of other threads
The task sched_yield() cause the calling thread to relinquish the CPU. The thread is put to the end of the queue for its static priority and another thread will be scheduled to run. If there are no other threads running in the system, the yield will cause the thread to continue to run.
sched_yield() is useful for an application to allow other threads to run (i.e. to prevent starvation of other threads) or for a thread to be scheduled in to reduce the latency for an scheduling event.
No arguments for this syscall.
To monitor context switches.
Example Use Case¶
sched_yield() should be used when a process needs to pause its execution and give a chance to the other threads, waiting in the same priority queue.
If there are no runnable threads with the same priority level, then the current thread will not be context switched and all other threads will be stuck behind it.
- sched_setscheduler: to change the scheduling policy and priority of selected thread.
- sched_get_priority_max/min: to get the highest/lowest priority limit of a scheduling policy.
