sched_yield -- yield processor
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-1993
(``POSIX.1'').
