Hallo Jochen,
I think they are save, and even saver that a solution with type casts
due to word boundaries. pos+1 does not need to point to a word
boundary, and you might run into trouble if you cast such a pointer,
though it might work on most compilers/systems.
The memory representation does not matter, as they are read and
written with the same method (I hope :-).
