| /* |
| * Test Name: llistxattr02 |
| * |
| * Description: |
| * 1) llistxattr(2) fails if the size of the list buffer is too small |
| * to hold the result. |
| * 2) llistxattr(2) fails if path is an empty string. |
| * 3) llistxattr(2) fails when attempted to read from a invalid address. |
| * 4) llistxattr(2) fails if path is longer than allowed. |
| * |
| * Expected Result: |
| * 1) llistxattr(2) should return -1 and set errno to ERANGE. |
| * 2) llistxattr(2) should return -1 and set errno to ENOENT. |
| * 3) llistxattr(2) should return -1 and set errno to EFAULT. |
| * 4) llistxattr(2) should return -1 and set errno to ENAMETOOLONG. |
