* Test Synopsis: Test calling pthread_exit from a Win32 thread
* having created an implicit POSIX handle for it.
*
* Test Method (Validation or Falsification):
* - Validate return value and that POSIX handle is created and destroyed.
*
* Requirements Tested:
* -
*
* Features Tested:
* -
*
* Cases Tested:
* -
*
* Description:
* -
*
* 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
*
* Pass Criteria:
* - Process returns zero exit status.
*
* Fail Criteria:
* - Process returns non-zero exit status.
