NAME
       sched_yield - yield the processor

SYNOPSIS
       #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 prior‐
       ity 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_PRIOR‐
       ITY_SCHEDULING in <unistd.h>.

RETURN VALUE
       On success, sched_yield() returns 0.  On error,	-1  is	returned,  and
       errno is set appropriately.

CONFORMING TO
       POSIX.1-2001.
