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



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(1,3) for its static priority and a new process gets(3,n) to run.

       Note:  If the current process is the only process in(1,8) the highest prior-
       ity list at that time(1,2,n), 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(1,8) <unistd.h>.


RETURN VALUE
       On success, sched_yield returns 0.  On error(8,n), -1 is returned, and errno
       is set(7,n,1 builtins) appropriately.


CONFORMING TO
       POSIX.1b (formerly POSIX.4)
