sched_yield − yield the processor
#include <sched.h>
int sched_yield(void);
A process can relinquish the processor voluntarily without blocking by calling sched_yield. The process will then be moved to the end of the queue for its static priority and a new process gets to run.
Note: If the current process is the only process in the highest priority list at that time, this process will continue to run after a call to sched_yield.
POSIX systems on which sched_yield is available define _POSIX_PRIORITY_SCHEDULING in <unistd.h>.
On success, sched_yield returns 0. On error, −1 is returned, and errno is set appropriately.
