Destroy a barrier-attributes object
#include <pthread.h>
int pthread_barrierattr_destroy(
pthread_barrierattr_t * attr );
- attr
- A pointer to the pthread_barrierattr_t object that
you want to destroy.

Use the -l c option to
qcc
to link against this library.
This library is usually included automatically.
The pthread_barrierattr_destroy() function
destroys the barrier-attributes object attr.
Subsequent use of the object is undefined until you reinitialize the object
by calling
pthread_barrierattr_init().
Once you've used a barrier-attributes object to initialize one or more
barriers, any changes to the attributes object (including destroying it)
don't affect any previously initialized barriers.
- EOK
- Success.
- EINVAL
- Invalid barrier attribute object attr.
