 * Test that pthread_detach()
 *
 * Upon failure, it shall return an error number:
 * -[EINVAL] The implemenation has detected that the value specified by
 * 'thread' does not refer to a joinable thread.
 * -[ESRCH] No thread could be found corresponding to that thread

 * It shall not return an error code of [EINTR]
 *
 * STEPS:
 * 1.Create a detached state thread
 * 2.Detach that thread
 * 3.Check the return value and make sure it is EINVAL
