Synopsis:

Use the -l c option to qcc to link against this library. This library is usually included automatically.
Description:
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.
Returns:
- EOK
- Success.
- EINVAL
- Invalid barrier attribute object attr.
