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”).
