[New-bugs-announce] [issue22781] ctypes: Differing results between Python and C.

[Geoff Clements]

New submission from Geoff Clements:

I have used ctypes to create a binding to libdvdread but I am getting some bad values back from libdvdread when using python. I have used ctypeslib to generate the python bindings, i.e. h2xml and xml2py and, as far as I can tell, the bind is a faithful representation of the h files.

In order to demonstrate this I have created a small C program and a small Python3 program both doing the same thing. When run they should produce the same output but they do not. In order to run these you need a DVD inserted in a DVD drive, I've hard-coded the device path to the DVD drive as /dev/sr0 in both programs so this may need to be changed.
