| * Test Synopsis: Test asynchronous cancelation (alertable or non-alertable). |
| * |
| * Test Method (Validation or Falsification): |
| * - |
| * |
| * Requirements Tested: |
| * - Async cancel if thread is not blocked (i.e. voluntarily resumes if blocked). |
| * |
| * 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, pthread_join. |
| * - quserex.dll and alertdrv.sys are not available. |
| * |
| * Pass Criteria: |
| * - Process returns zero exit status. |
| * |
| * Fail Criteria: |
| * - Process returns non-zero exit status. |
