If you have the header files,
have a look at www.drbob42.com as there is an automated conversion program
for C header files - it does most of it for you - it is not 100% correct but
is very good.

> #ifndef DLLEXPORT
> #define DLLEXPORT __declspec( dllexport )
> #endif
> then at the end of the header file there is:
> DLLEXPORT VisInfo* QueryModule(void); /* exported DLL */
> I understand that DLLEXPORT will be replaced with __declspec( dllexport

> but it's the only place so why bother defining it? And what does it do?

> 4) Can I ignore the #pragmas? There is only one (used in a couple of
> places):
> #pragma pack (push, 8) and #pragma pack (pop, 8)
>
> 5) When compiling are there any special flags etc that I should use to
