How is it encoded? Binary numbers usually differ in endianness. If you want to assume it’s the same as the current host’s endianness, you can use
freaddirectly. Otherwise, you’ll need to byte-swap it after reading.For bonus points, assuming you have control over how it’s serialized, you could indicate the endianness with some flag or byte order mark.
