-/*
- * File: condvar3_1.c
- *
- * Test Synopsis:
- * - Test timeout of multiple waits on a CV with some signaled.
- *
- * Test Method (Validation or Falsification):
- * - Validation
- *
- * Requirements Tested:
- * -
- *
- * Features Tested:
- * -
- *
- * Cases Tested:
- * -
- *
- * Description:
- * - Because some CVs are never signaled, we expect their waits to time out.
- * Some are signaled, the rest time out. Pthread_cond_destroy() will fail
- * unless all are accounted for, either signaled or timedout.
- *
- * Environment:
- * -
- *
- * Input:
- * - None.
- *
- * Output:
- * - File name, Line number, and failed expression on failure.
- * - No output on success.
- *
- * Assumptions:
- * -
- *
- * Pass Criteria:
- * - pthread_cond_timedwait returns ETIMEDOUT.
- * - Process returns zero exit status.
- *
- * Fail Criteria:
- * - pthread_cond_timedwait does not return ETIMEDOUT.
- * - Process returns non-zero exit status.
