pthread_barrierattr_destroy()

Destroy a barrier-attributes object

Synopsis:

#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.

Classification:

POSIX 1003.1 THR BAR

Safety:
Cancellation point No
Interrupt handler No
Signal handler Yes
Thread Yes
