Is it safe to use boost serialization to serialize objects in C++ to a binary format for use over a socket?

Question

I know that you can use boost serialization to serialize to a text format and then push over a socket, but I'd like to serialize a class of statistics data into a binary format (both for size and encoding/decoding overhead reasons). Is it safe to use boost serialization for this?

My specific worries are:

1. Differences between integer type sizes on different platforms (mainly 32-bit vs 64-bit).
   Though I can largely get around this by using exactly-sized integer from stdint, I'd still like to understand the behavior.
2. Differences in endianness between systems, does boost serialize into a standard endian-ness (eg: network ordering), and then deserialize using the host's endianness?

It's a very nice library, but unfortunately documentation on it's binary capabilities is somewhat limited, so I just want to make sure that using it this way would be safe.

Answer 1

No, in general boost binary serialization is not machine-independent. See here.
