Section (3) pthread_yield
pthread_yield — yield the processor
#define _GNU_SOURCE /* See feature_test_macros(7) */ #include <pthread.h>
Compile and link with
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
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 attributes(7).
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_RR). Use of
pthread_yield() with nondeterministic
scheduling policies such as
SCHED_OTHER is unspecified and very likely
means your application design is broken.
