sched_yield() - Unix, Linux System Call
Advertisements
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
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.
CONFORMING TO
POSIX.1-2001.
