  He did not say he was communicating with some other program that
expected a certain byte order, so he's free to choose any order he wants.
Of course the C program might be on another machine with another byte
order, or another floating point representation, etc, so he might need
to convert a 32 bit "word" on machine A to the equivalent on machine B.
