Dear All,
  I am trying to implement an interface from the BBox to the
Excalibur digital receiver (http://www.winradio.co.uk/home/g31ddc.htm)
using the provided DLL library. I came across some strange (at least
for me) C/C++ constructs, and I do not know how to map them to the
CP:


DECLARE_INTERFACE(IG31DDCDeviceEnumerator)
{
    STDMETHOD_(LONG,AddRef)(THIS) PURE;
    STDMETHOD_(LONG,Release)(THIS) PURE;

    STDMETHOD_(BOOL,Enumerate)(THIS) PURE;
    STDMETHOD_(UINT32,GetCount)(THIS) PURE;
    STDMETHOD_(BOOL,GetDeviceInfo)(THIS_ UINT32
DeviceIndex,G31DDC_DEVICE_INFO *DeviceInfo,UINT32 BufferLength) PURE;
};

also how I should map the following construct to CP?

 BOOL __stdcall CreateInstance(UINT32 ClassId,void **Intf);
 (my fist solution was: fcn_map : PROCEDURE (ClassId :INTEGER; Inft
: ANYPTR):BOOLEAN but I not sure if it makes any sense).

The DLL has only one entry that allows creation of two objects, and
the rest of functionality is (somehow) embedded within the object's
code.
 How should I approach this kind of interfaces?

 Any tips & tricks are very welcome.

 Regards,
   Darek
