NAME

sched_yield − yield processor

SYNOPSIS

cc [ flag ... ] file ... −lposix4 [ library ... ]

#include <sched.h>

int sched_yield(void);

MT-LEVEL

MT-Safe

DESCRIPTION

sched_yield() forces the running process to relinquish the processor until the process again becomes the head of its process list. 

RETURN VALUES

If successful, sched_yield() returns 0, otherwise, it returns -1, and sets errno to indicate the error condition. 

ERRORS

ENOSYS sched_yield() is not supported by this implementation.

BUGS

In Solaris 2.5, these functions always return −1 and set errno to ENOSYS, because this release does not support the Priority Scheduling option.  It is our intention to provide support for these interfaces in future releases.
