BSTR is a wide string, so your declaration would be ‘P’ (or  
‘L’ if you plan on passing addresses around).

I’ve never dealt with BSTR directly, but it looks like you may  
have to manipulate your strings with MultiByteToWideChar() and  
WideCharToMultiByte() first, before passing them to whatever  
function you use that requires BSTR data types.

If you can provide an example of something you’re having  
trouble with we can probably help you better.
