Linking .dll files written in C++

Hi,
I am currently doing a final year project using JADE and the project requires us to link to a hardware using the provided driver. Thus I would like to know how to link to .dll files and drivers stored in other extensions. (eg .bfd). By the way, some functions in the driver does not return a char pointer, instead it returns a pointer to a handler and how would i be able to access the address in the handler in JADE ? Thanks alot.

A handle is basically a pointer to a piece of memory, which on x86 is a 32 bit integer. This can be represented in Jade as an Integer variable. This handle can be passed to other external functions as Integers. You may need to cast these in the .dll to the appropriate data type.

I am not familiar with .bfd files sorry. If you can do it in C++ then you can so it in JADE in the sense that you can export functions in a dll that can then be called frmo within a JADE application.

Regards,
Allistar.
