OK, now it runs.
But the strage thing is.

Thas it works in the following way (5 or 6 times in my code)

void (pointer) (void **,int*,void*);

and in the next line

pointer = CallBackFunction;

Without the & before the function and without the typedef.

And the error message is realy confusing for me.

Thanks
