36 * Test Synopsis:
37 * - Test timed wait on a CV.
38 *
39 * Test Method (Validation or Falsification):
40 * - Validation
41 *
42 * Requirements Tested:
43 * -
44 *
45 * Features Tested:
46 * -
47 *
48 * Cases Tested:
49 * -
50 *
51 * Description:
52 * - Because the CV is never signaled, we expect the wait to time out.
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 * -
66 *
67 * Pass Criteria:
68 * - pthread_cond_timedwait returns ETIMEDOUT.
69 * - Process returns zero exit status.
70 *
71 * Fail Criteria:
72 * - pthread_cond_timedwait does not return ETIMEDOUT.
73 * - Process returns non-zero exit status.
