* Name: pthread_barrierattr_setpshared
|
|
*
|
|
* Description:
|
|
* The process-shared attribute is set to PTHREAD_PROCESS_SHARED to permit
|
|
* a barrier to be operated upon by any thread that has access to the
|
|
* memory where the barrier is allocated. If the process-shared attribute
|
|
* is PTHREAD_PROCESS_PRIVATE, the barrier can only be operated upon by
|
|
* threads created within the same process as the thread that initialized
|
|
* the barrier.
|
|
* If threads of different processes attempt to operate on such a barrier,
|
|
* the behavior is undefined. The default value of the attribute is
|
|
* PTHREAD_PROCESS_PRIVATE.
|
|
*
|
|
* Both constants PTHREAD_PROCESS_SHARED and PTHREAD_PROCESS_PRIVATE are
|
|
* defined in pthread.h.
|
|
*
|
|
* Input Parameters:
|
|
* attr - barrier attributes to be modified.
|
|
* pshared - the new value of the pshared attribute.
|
|
*
|
|
* Returned Value:
|
|
* 0 (OK) on success or EINVAL if either attr is invalid or pshared is not
|
|
* one of PTHREAD_PROCESS_SHARED or PTHREAD_PROCESS_PRIVATE.
|
|
*
|
|
* Assumptions:
|
|
*
