Get the value of a barrier's process-shared attribute
#include <pthread.h>
int pthread_barrierattr_getpshared(
const pthread_barrierattr_t * attr
int * pshared );
- attr
- A pointer to the pthread_barrierattr_t object whose
attribute you want to query.
You must have initialized this object by calling
pthread_barrierattr_init()
before calling pthread_barrierattr_getpshared().
- pshared
- A pointer to a location where the function can store the value of the
process-shared attribute.
For information about the possible values, see
pthread_barrierattr_setpshared().

process-shared attribute from the attributes object referenced by
attr and stores the value in the object referenced by
pshared.
- EOK
- Success.
