No header file

[James Howe]

No header is provided in order to link against the shared library.

The Python example provides some clues to the API but is not sufficient, especially for the magic number parameters.

Aha, I found them after all:

Are you able to put them in the download packages from the OS website, or is that out of your control?

[Paul Michell]

James, I’m afraid some of the examples were developed after the official release and are not part of the download for that reason and yes, as you say, the files on the OS website are not under my control.
