sched_yield — yield processor

LIBRARY¶

Standard C Library (libc, -lc)

DESCRIPTION¶

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.

RETURN VALUES¶

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.

ERRORS¶

On failure errno will be set to the corresponding value:

[ENOSYS]

The system is not configured to support this functionality.

STANDARDS¶

The sched_yield() system call conforms to IEEE Std 1003.1b-1993 (“POSIX.1b”).
