Ok while sizeof(Myenum) and sizeof(int) works, I would like to use sizeof(object), but I don’t want the size of the object, but the size of pointer… only for portability reason, I need to know if is a 64 bit pointer or 32 bit pointer, I can avoid using sizeof if is ok with conditional compilation, but I don’t know if there are constants to check if we are on a 32 bit system instead of 64 bit

Thanks for suggestions
