IUnknown: Products, Methods & Implementations on other platforms

In the computer programming of applications on Microsoft Windows through the Windows API, the IUnknown interface is the fundamental interface of Component Object Model (COM). The COM specification mandates that COM objects must implement this interface. Furthermore, every other COM interface must be derived from IUnknown. IUnknown resides in the global…
