IUnknown Interface

  • Article

The IUnknown interface contains three basic functions: the QueryInterface() function, the AddRef() function, and the Release() function.

The IImeActiveDict interface follows the COM specification. The COM interface must be binary compatible and can be written by any computer language that supports function pointers. C++ is the recommended language, because it is object oriented and supports inheritance.
