[Tinyos-help] Accessing whole word(16bits)

[Paul Stickney]

Use an nx_[u]int16_t field in your message structure.
You can define multiple message structures and overlay or use (but I
wouldn't recommend it) unions of structures.

Or explicitly "deconvert" in a compatible manner.
You *could* use a cast if endians align, but this is just bad behavior
to rely on.
Pay attention to the warning messages--the num * pointer is likely wrong.

HTH,
Paul
