 * Test that pthread_rwlockattr_getpshared()
 *
 *  It shall obtain the value of the process-shared attribute from 'attr'.
 *  The default value of the process-shared attribute shall be PTHREAD_PROCESS_PRIVATE.
 *
 * 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.
