pthread_barrierattr_destroy()

Destroy a barrier-attributes object

#include <pthread.h>

int pthread_barrierattr_destroy( 
                   pthread_barrierattr_t * attr );

Arguments:

attr

A pointer to the pthread_barrierattr_t object that you want to destroy.

Library:

libc

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.
