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
R 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
R sched_yield ().
POSIX systems on which
R sched_yield ()
is available define
_POSIX_PRIORITY_SCHEDULING
in <unistd.h>.
RETURN VALUE
On success,
R sched_yield ()
returns 0.
On error, -1 is returned, and
errno
is set appropriately.
ERRORS
In the Linux implementation,
R sched_yield ()
always succeeds.
