The functions of the software development kit are exported with the call convention "_cdecl". Visual Basic 6.0 needs however functions with the convention "_stdcall " (pascal convention). You can call up the FALCON/EAGLE functions directly from Visual Basic 6.0, if you replace the functions is_<function name> by iss_<function name>.
All "is_<Function name>" functions are _cdecl functions. _stdcall functions exist parallel to these functions as "iss_<Function name>". Function parameters and return values are identical. A small Visual Basic project is contained in the scope of delivery created with Visual Basic 6.0. It can only be opened with Visual Basic 6.0 or higher.
