Look up the htons, nstoh, htonl, nltoh, WSAHtonl, ... functions. These
functions convert from whatever the hardware uses natively to a neutral
consistent ordering. If you use the same functions on the different
platforms (well, OK, the WSAHxxx functions are Windows specific), then
it should all work fine, since the different platforms will supply their
own versions which Just Do The Right Thing.

Note that the functions may just return whatever they're fed with if
that's already in network order.
