- * Test Synopsis:
- * - Test basic function of a CV
- *
- * Test Method (Validation or Falsification):
- * - Validation
- *
- * Requirements Tested:
- * -
- *
- * Features Tested:
- * -
- *
- * Cases Tested:
- * -
- *
- * Description:
- * - The primary thread takes the lock before creating any threads.
- * The secondary thread blocks on the lock allowing the primary
- * thread to enter the cv wait state which releases the lock.
- * The secondary thread then takes the lock and signals the waiting
- * primary thread.
- *
- * Environment:
- * -
- *
- * Input:
- * - None.
- *
- * Output:
- * - File name, Line number, and failed expression on failure.
- * - No output on success.
- *
- * Assumptions:
- * -
- *
- * Pass Criteria:
- * - pthread_cond_timedwait returns 0.
- * - Process returns zero exit status.
- *
- * Fail Criteria:
- * - pthread_cond_timedwait returns ETIMEDOUT.
- * - Process returns non-zero exit status.
