 * Test that pthread_attr_setdetachstate()
 *   
 * If the thread is created detached, then use of the ID of the newly created 
 * thread by the pthread_detach() or pthread_join() function is an error.
 * 
 * Steps:
 * 1.  Initialize a pthread_attr_t object using pthread_attr_init().
 * 2.  Using pthread_attr_setdetachstate(), set the detachstate to 
 *     PTHREAD_CREATE_DETACHED.
 * 3.  Create a thread with this attribute.     
 * 4.  Call pthread_detach() and pthread_join() on this thread, it should give
 *     an error.      
 *
