Creating standalone COM objects... [message #436259]

If I implement IUnknown (as is done in say OleClientSite), is it usable from
any arbitrary COM object? I ask this because I was trying to understand the
implementation in callback.c and it seems like that when a Vtlb is created
through COMObject and Callback(in java) classes, all the functions are
supposed to take jint arguments. Moreover, when a function is called
(callback.c's callback function) the va_arg macro is passed jint so if the
function is called as a result of QueryInterface(IID...), what will the
first param contain?

Thanks,
