SCHED_YIELD(2)             Linux Programmer's Manual            SCHED_YIELD(2)



NAME
       sched_yield - yield the processor

SYNOPSIS
       #include <&lt;sched.h>&gt;

       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 calling 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 &lt;unistd.h&gt;.

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
       POSIX.1-2001.
