36  * Test Synopsis: Test calling pthread_exit from a Win32 thread
37  *                without having created an implicit POSIX handle for it.
38  *
39  * Test Method (Validation or Falsification):
40  * -
41  *
42  * Requirements Tested:
43  * -
44  *
45  * Features Tested:
46  * -
47  *
48  * Cases Tested:
49  * -
50  *
51  * Description:
52  * -
53  *
54  * Environment:
55  * -
56  *
57  * Input:
58  * - None.
59  *
60  * Output:
61  * - File name, Line number, and failed expression on failure.
62  * - No output on success.
63  *
64  * Assumptions:
65  * - have working pthread_create, pthread_self, pthread_mutex_lock/unlock
66  *   pthread_testcancel, pthread_cancel, pthread_join
67  *
68  * Pass Criteria:
69  * - Process returns zero exit status.
70  *
71  * Fail Criteria:
72  * - Process returns non-zero exit status.
