Hang on - isn't this back to front?

If the structure is declared as exportable from the DLL, then he
doesn't want to define some memory that he can export as a function,
he wants to read and write it, having imported it from the DLL

In which case, it's just a matter of casing the return value of
GetProcAddress right?

Or am I being silly?
