pthread_yield - yield the processor
#define _GNU_SOURCE /* See feature_test_macros(7) */
#include <pthread.h>
int pthread_yield(void);
Compile and link with
-pthread.
pthread_yield() causes the calling thread to relinquish the CPU. The
thread is placed at the end of the run queue for its static priority and
another thread is scheduled to run. For further details, see
sched_yield(2)
On success,
pthread_yield() returns 0; on error, it returns an error
number.
On Linux, this call always succeeds (but portable and future-proof applications
should nevertheless handle a possible error return).
For an explanation of the terms used in this section, see

This call is nonstandard, but present on several other systems. Use the
standardized
sched_yield(2) instead.
On Linux, this function is implemented as a call to
sched_yield(2).
pthread_yield() is intended for use with real-time scheduling policies
(i.e.,
SCHED_FIFO or
SCHED_RR). Use of
pthread_yield()
with nondeterministic scheduling policies such as
SCHED_OTHER is
unspecified and very likely means your application design is broken.
