| * 2. Too many symbolic links were encountered in translating path, |
| * ELOOP would return. |
| * 3. path is too long, ENAMETOOLONG would return. |
| * 4. The file referred to by path does not exist, ENOENT would return. |
| * 5. A component of the path prefix of path is not a directory, |
| * ENOENT would return. |
