About API Documentation

Do we have any copy of the offline C++ API Documentation, any pdfs or chm file of the documentation. Can somebody post a link if possible?

as far as I know there is only the panda manual available for download.

I am not sure if the C++ references or any of the python API references can be downloaded as well.
