Where can I find a documentation for WinCC OA API functions?

Due to the fact that our WinCC OA API contains a great number of functions and classes we decided to split the details from the WinCC OA Help and use a seperate documentation for the API.
The API documentation has been created using Doxygen and can be found inside your WinCC OA installation directory under the folder "/api/docu/" when the API-package is installed.
To open the documentation, navigate to the "index.html" file located inside the "/api/docu/" folder and open it with a web browser of your choice.

Please note: A short introduction and the basics for creating own drivers with the WinCC OA API can also be found in our WinCC OA Documentation.
