  man pages->Linux man pages -> sched_yield (2)              



NAME    [Toc]    [Back]

       sched_yield - yield the processor

SYNOPSIS    [Toc]    [Back]

       #include <sched.h>

       int sched_yield(void);

DESCRIPTION    [Toc]    [Back]

       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_PRIOR-
       ITY_SCHEDULING in <unistd.h>.

RETURN VALUE    [Toc]    [Back]

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

CONFORMING TO    [Toc]    [Back]

       POSIX.1b (formerly POSIX.4)
