NAME
sched_yield - yield the processorSYNOPSIS
#include <sched.h>int sched_yield(void);
DESCRIPTION
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>.
RETURN VALUE
On success, sched_yield() returns 0. On error, -1 is returned, and errno is set appropriately.ERRORS
In the Linux implementation, sched_yield() always succeeds.CONFORMING TO
