# realpath
2+
3+
Example program how to retrieve the real path of a file or directory that
4+
may be bind mounted into a Windows container.
5+
6+
But the function `GetFinalPathNameByHandle()` doesn't seem to retrieve us
7+
at least the absolute path of the file/directory given.
8+
It just returns with error 53 ERROR_BAD_NETPATH: The network path was not found.
9+
10+
```
