NAME

     sched_yield -- yield processor

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <sched.h>

     int
     sched_yield(void);

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.1'').
