But you are actually writing a varint32, which can be anywhere
between 1 and 5 bytes depending on the value.
Use CodedOutputStream::Varint32Size() to compute the number of bytes
needed to encode a particular value.
This has the advantage that you can allocate a buffer of exactly the
right size, rather than adding 100 as an estimate. However, you can
also find the final size after all the writes with
CodedOutputStream::ByteCount()
You should not need to do any byte swapping if you are serializing and
deserializing integers using the protobuf API: it handles any required
byte swapping for you.
