Destroy a barrier object
#include <pthread.h> int pthread_barrier_destroy( pthread_barrier_t * barrier );
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The pthread_barrier_destroy() function destroys the barrier referenced by barrier and releases any resources used by the barrier. Subsequent use of the barrier is undefined until you reinitialize the barrier by calling pthread_barrier_init().
