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.1b (formerly POSIX.4)
