 | 
						|
 * Test Synopsis: Test setting cancel state and cancel type.
 | 
						|
 * - 
 | 
						|
 *
 | 
						|
 * Test Method (Validation or Falsification):
 | 
						|
 * - 
 | 
						|
 *
 | 
						|
 * Requirements Tested:
 | 
						|
 * - pthread_setcancelstate function
 | 
						|
 * - pthread_setcanceltype function
 | 
						|
 *
 | 
						|
 * Features Tested:
 | 
						|
 * - 
 | 
						|
 *
 | 
						|
 * Cases Tested:

 * Input:
 | 
						|
 * - None.
 |

 *
 | 
						|
 * Output:
 | 
						|
 * - File name, Line number, and failed expression on failure.
 | 
						|
 * - No output on success.
 | 
						|
 *
 | 
						|
 * Assumptions:
 | 
						|
 * - pthread_create, pthread_self work.
 | 
						|
 *
 | 
						|
 * Pass Criteria:
 | 
						|
 * - Process returns zero exit status.
 | 
						|
 *
 | 
						|
 * Fail Criteria:
 | 
						|
 * - Process returns non-zero exit status.
