| * Test that clock_settime() sets errno=EINVAL if tp has a nsec value < 0 or |
| * >= 1000 million. |
| * |
| * Test calling clock_settime() with the following tp.tv_nsec values: |
| * MIN INT = INT32_MIN |
| * MAX INT = INT32_MAX |
| * MIN INT - 1 = 2147483647 (this is what gcc will set to) |
| * MAX INT + 1 = -2147483647 (this is what gcc will set to) |
| * unassigned value = -1073743192 (ex. of what gcc will set to) |
| * unassigned value = 1073743192 (ex. of what gcc will set to) |
| * -1 |
| * 1000000000 |
| * 1000000001 |
| * |
| * The clock_id CLOCK_REALTIME is used. |
