42  * Test Synopsis:
43  * - Test timed wait on a CV.
44  *
45  * Test Method (Validation or Falsification):
46  * - Validation
47  *
48  * Requirements Tested:
49  * -
50  *
51  * Features Tested:
52  * -
53  *
54  * Cases Tested:
55  * -
56  *
57  * Description:
58  * - Because the CV is never signaled, we expect the wait to time out.
59  *
60  * Environment:
61  * -
62  *
63  * Input:
64  * - None.
65  *
66  * Output:
67  * - File name, Line number, and failed expression on failure.
68  * - No output on success.
69  *
70  * Assumptions:
71  * -
72  *
73  * Pass Criteria:
74  * - pthread_cond_timedwait returns ETIMEDOUT.
75  * - Process returns zero exit status.
76  *
77  * Fail Criteria:
78  * - pthread_cond_timedwait does not return ETIMEDOUT.
79  * - Process returns non-zero exit status.
