Destroying a Barrier Attributes Object

The pthread_barrierattr_destroy() function destroys a barrier attributes object. A destroyed attr attributes object can be reinitialized using pthread_barrierattr_init().

After a barrier attributes object has been used to initialize one or more barriers, destroying the object does not affect any previously initialized barrier.
