But if there are multiple threads and one thread is completed then that id can be reused. Full example of pthread_cond_timedwait The following code has two threads. For more information about cancelability see Thread cancellation APIs.

Wait for thread to exit int err pthread_jointhreadId. Once the main thread receives its signal it will join the pthread and terminate. Int pthread_rwlock_timedrdlock pthread_rwlock_t rwlock_ const struct timespec ts rwlock_t rwlock.
