What about integral promotion? I.e. what if the platform int isn't 4 bytes?
What if you need to output 1 or 2 bytes?

Rather than a machine and compiler-dependent binary IO facility based on
iostreams, I'd rather have a simple, minimal, portable binary streaming
interface that handled endianness and alignment well for
wire-representation defined structures.
<iostream> brings in a huge header tree with 99% unnecessary
functionality for binary protocols. The more efficient the headers, the
better. Functions that didn't need to read could just include the header
for writing, and vice-versa.
