| * Description: |
| * Verify that, |
| * 1) utimes() returns -1 and sets errno to EACCES if times |
| * is NULL, the caller's effective user ID does not match |
| * the owner of the file, the caller does not have write |
| * access to the file, and the caller is not privileged. |
| * 2) utimes() returns -1 and sets errno to ENOENT if filename |
| * does not exist. |
| * 3) utimes() returns -1 and sets errno to EFAULT if filename |
| * is NULL. |
| * 4) utimes() returns -1 and sets errno to EPERM if times is |
| * not NULL, the caller's effective UID does not match the |
| * owner of the file, and the caller is not privileged. |
| * 5) utimes() returns -1 and sets errno to EROFS if path resides |
| * on a read-only file system. |
