Hm thanks for all your help. I knew that my function cast was wrong
but I tried to do this in that way because VC6 SP5 does not allow me
using the predefined macros, if i do i get a type mismatch error...
since
(VALUE)(*)(...)) is different from (VALUE)(*)()) which all rb_define
methods want ..... does anybody know a workaround for this ..

To the first answer, I do not need an InitXXY Method or export because
i am embedding ruby in my application so the extension module is
built-in...

Thanks
