 | 
						|
 * Input:
 | 
						|
 * - None.
 | 
						|
 *
 | 
						|
 * Output:
 | 
						|
 * - File name, Line number, and failed expression on failure.
 | 
						|
 * - No output on success.
 | 
						|
 *
 | 
						|
 * Assumptions:
 |

 *   pthread_testcancel, pthread_cancel, pthread_join
 | 
						|
 *
 | 
						|
 * Pass Criteria:
 | 
						|
 * - Process returns zero exit status.
