You mean COM interfaces? I usually do this:
interface SomeComInterface : IUnknown

     extern(Windows):

But maybe this is already implicit when deriving from IUnknown, I wouldn't know.

But from what I can tell some of those prototypes seem to have C
linkage, maybe you're getting access violations due to wrong calling
conventions.


Thanks for the reply. But it still doesn't work.

interface ISomeComInterface : IUnknown
{
        void funcWithManyParams(/*10 params*/);

        extern(/*insert whatever linkage here*/)
        void funcWrapperWithLessParams(/*3 params*/)
        {
                funcWithManyParams(/*fill in some default params*/);
        }
        //this func is inlined in the MS SDK header
}

DMD complains that the function body of funcWrapperWithLessParams isn't 
abstract.
