+ * Name: pthread_barrier_destroy
+ *
+ * Description:
+ *   The pthread_barrier_destroy() function destroys the barrier referenced by
+ *   'barrier' and releases any resources used by the barrier. The effect of
+ *   subsequent use of the barrier is undefined until the barrier is
+ *   reinitialized by another call to pthread_barrier_init(). The results are
+ *   undefined if pthread_barrier_destroy() is called when any thread is blocked
+ *   on the barrier, or if this function is called with an uninitialized barrier.
+ *
+ * Parameters:
+ *   barrier - barrier to be destroyed.
+ *
+ * Return Value:
+ *   0 (OK) on success or on of the following error numbers:
+ *
+ *   EBUSY  The implementation has detected an attempt to destroy a barrier while
+ *           it is in use.
+ *   EINVAL The value specified by barrier is invalid.
+ *
+ * Assumptions:
