|
* Test Synopsis:
|
|
* - Test timeout of multiple waits on a CV with no signal/broadcast.
|
|
*
|
|
* Test Method (Validation or Falsification):
|
|
* - Validation
|
|
*
|
|
* Requirements Tested:
|
|
* -
|
|
*
|
|
* Features Tested:
|
|
* -
|
|
*
|
|
* Cases Tested:
|
|
* -
|
|
*
|
|
* Description:
|
|
* - Because the CV is never signaled, we expect the waits to time out.
|
|
*
|
|
* 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.
