Since your C file only deals with the structure via pointers to void,
moving the class into a name space will have no effect.

Note, that the functions you are declaring to return/take pointers to
void, really do return/take pointers to void, and the functions do the
casting to Apple* inside.

The thing to note is that by definition, a pointer to ANY type/object
can be converted to a pointer to void and back to its original type and
it will point to the same object.
