 * Test that pthread_rwlockattr_init()
 *   shall initialize a read-write attributes object 'attr' with the default
 *   value for all of the attributes defined by the implementation.

 * Steps:
 * 1.  Initialize a pthread_rwlockattr_t object with pthread_rwlockattr_init()
 * 2.  Call pthread_rwlockattr_getpshared() to check if the process-shared
 *     attribute is set as the default value PTHREAD_PROCESS_PRIVATE.
