obj_base.h patch

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This is supposed to make it easier for widl to emit a reasonably simple
definition for that ancestorless COM base class (IUnknown).

Log:
Ove Kaaven <ovek@transgaming.com>
Add ICOM_DEFINE1 macro to define a COM interface without a base class.
Use it to define IUnknown.
