Similarly, the internal implementation of the API's function has been developed in several languages, historically. Despite the fact that C is not an language, the Windows API and Windows have both historically been described as object-oriented. There have also been many wrapper classes and extensions (from Microsoft and others) for object-oriented languages that make this object-oriented structure more explicit ( (MFC), (VCL),, etc.).
