| * Test to see if timer_delete() returns -1 and sets errno==EINVAL when |
| * trying to delete a timer that has already been deleted or not. |
| * Since this is a "may" assertion, either option is a pass. |
| * Steps: |
| * - Run test case 1-1.c and then try to delete the timer again. |
| * |
| * For this test, signal SIGTOTEST will be used, clock CLOCK_REALTIME |
| * will be used. |
