There is always a way to define your data types with correct sizes
in your toolchain (compiler is most affected). AFAIK, exact sizes
are not specified by C++ standard (it is by C, I think).
Well, C99 typedefs int32_t for a 32 bit type *if there is one*. If int
happens to be 36 or 48 bits, the typedef would be missing.
C++0x will do the same.
You use a
"tailor" header for that. Said header is shipped for any toolchain
you will support.
You define your serialized/streamed/marshaled format in a toolchain-
agnostic manner. Specifically for numbers, you need to know the
endiannes, too. That influences they way you (de)serialize them on
the sending/receiving sides.
Right, you define the transport format for the network, and implement
that on each platform. VERY hard to do that portably.
