	Actually, you have to reference the class' virtual function tables
through C.  For instance, if lpDD is a DirectDraw object and you want to
call its Release() method, instead of lpDD->Release(), use
lpDD->lpVtbl->Release(lpDD).  For each method, you must provide the
"object" (in this case lpDD) as the first parameter.  This is why the
Release() method which normally takes no parameters in C++ must take the
lpDD parameter in C.
