| 1 | | = Finding a Directory's Path = |
| 2 | | When referencing paths, it is best to use Haiku's Find Directory functionality. The system defines numerous key directories in the [http://dev.haiku-os.org/browser/haiku/trunk/headers/os/storage/FindDirectory.h os/storage/FindDirectory.h] header. In addition to C/C++, a command line utility `finddir` can be used with the same variable names. |
