/*
* File: condvar2_1.c
*
* 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.
