sched_yield — yield the processor
#include <sched.h>
int
sched_yield( |
void) ; |
A process can relinquish the processor voluntarily without
blocking by calling sched_yield

moved to the end of the queue for its static priority and a
new process gets to run.

If the current process is the only process in the
highest priority list at that time, this process will
continue to run after a call to |
POSIX systems on which sched_yield
() is available define
_POSIX_PRIORITY_SCHEDULING

<unistd.h>.
On success, sched_yield
()
returns 0. On error, −1 is returned, and errno
is set appropriately.
