sched_yield – yield processor

LIBRARY SYNOPSIS DESCRIPTION RETURN VALUES ERRORS STANDARDS

Standard C Library (libc, -lc)

#include <sched.h>

int
sched_yield(void);

The sched_yield() system call forces the running process to relinquish the processor until it again becomes the head of its process list. It takes no arguments.

The sched_yield function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to indicate the error.

On failure errno will be set to the corresponding value:

[ENOSYS]
	The system is not configured to support this functionality.

The sched_yield() system call conforms to IEEE Std 1003.1b-93 ("POSIX.1").
