 * Test that pthread_rwlockattr_setpshared()
 *
 *  It shall set the value of the process-shared attribute from 'attr'.
 *
 * Steps:
 * 1.  Initialize a pthread_rwlockattr_t object with pthread_rwlockattr_init().
 * 2.  Set the process shared to PTHREAD_PROCESS_PRIVATE.
 * 3.  Get the attribute and test whether the setting in step 2 is correct.
 * 4.  Set the process shared to PTHREAD_PROCESS_SHARED.
 * 5.  Get the attribute and test whether the setting in step 4 is correct.
