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).
The pthread_yield() function is thread-safe.
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).
