NAME

sched_yield — yield the processor

SYNOPSIS

#include <sched.h>

int
sched_yield(void);

The sched_yield() function makes the current thread yield the processor and be put at the end of its run queue without altering its priority.

Upon successful completion, the value 0 is returned; otherwise the value -1 is returned and the global variable errno is set to indicate the error.

The sched_yield() function conforms to IEEE Std 1003.1-2008 (“POSIX.1”).

The sched_yield() system call appeared in OpenBSD 4.2.

The effect of sched_yield() is only precisely defined for real-time scheduling classes, none of which are currently supported by OpenBSD.
