8  * Test that pthread_detach()
9  *
10  * Upon failure, it shall return an error number:
11  * -[EINVAL] The implemenation has detected that the value specified by
12  * 'thread' does not refer to a joinable thread.
13  * -[ESRCH] No thread could be found corresponding to that thread
14 
15  * It shall not return an error code of [EINTR]
16  *
17  * STEPS:
18  * 1.Create a detached state thread
19  * 2.Detach that thread
20  * 3.Check the return value and make sure it is EINVAL
