Hi,

use it ?

Thanks.

"void" is 'nothing', so it is useless in a managed world (where the
datatype can be reflected)...

If you want to pass an pointer you can use "IntPtr"...

But in general you should make an wrapper around the unmanaged
class/data; this also means that you should never returns som unknown
object to the managed world...
