* Test Synopsis: Test passing of exceptions back to the application.
|
|
*
|
|
* Test Method (Validation or Falsification):
|
|
* -
|
|
*
|
|
* Requirements Tested:
|
|
* -
|
|
*
|
|
* Features Tested:
|
|
* -
|
|

|
|
*
|
|
* Environment:
|
|
* -
|
|
*
|
|
* Input:
|
|
* - None.
|
|
*
|
|
* Output:
|
|
* - File name, Line number, and failed expression on failure.
|
|
* - No output on success.
|
|
*
|
|
* Assumptions:
|
|
* - have working pthread_create, pthread_self, pthread_mutex_lock/unlock
|
|
* pthread_testcancel, pthread_cancel, pthread_join
|
|
*
|
|
* Pass Criteria:
|
|
* - Process returns zero exit status.
|
|
*
|
|
* Fail Criteria:
|
|
* - Process returns non-zero exit status.
