| * Basic tests for getxattr(2) and make sure getxattr(2) handles error |
| * conditions correctly. |
| * |
| * There are 4 test cases: |
| * 1. Get an non-existing attribute, |
| * getxattr(2) should return -1 and set errno to ENOATTR |
| * 2. Buffer size is smaller than attribute value size, |
| * getxattr(2) should return -1 and set errno to ERANGE |
| * 3. Get attribute, getxattr(2) should succeed |
| * 4. Verify the attribute got by getxattr(2) is same as the value we set |
