Your idea would work, so go for it if you want, but I find that clean code is happy code .
Why not just do a reinterpret_cast to a char* or a memcpy into a char buffer? They're basically the same thing and less confusing .

Hi all,
I have a C++ method signature that looks like this:

I don't see an obvious problem with your code.
You do not free it also.
Also, OLE2A may allocate memory due to conversion (take a look) .
This memory is allocated on server side.
I guess you need to destroy request with ::SysFreeString().
