Is there a set of functions that do the oposite to the *ptr functions.
I want to be able to get a pointer as the parameter for a native DLL to
avoid the ANSI to UNICODE conversion.

I don't see how that's the opposite of the xPtr functions, it's
exactly what StrPtr does -- it gives you a pointer to a Unicode BSTR
that you can pass out to external code.

But can I write a DLL that is being passed a pointer and use that
pointer with a VB function or should I investigate the CopyMemory API?

I don't know what you really want. Something more concrete might help,
maybe an example or some code. What is your larger goal here?

What language will the DLL be written in? How will it be invoked
(Declare, COM, ??). What do you mean by 'and use that pointer with a
VB function'? I thought you asked about passing a pointer OUT of a VB
function.
