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 calling 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.

ERRORS

In the Linux implementation, sched_yield () always succeeds.

CONFORMING TO

POSIX.1-2001.
