Get access to raw buffer for usage within MPI (message parsing interface)

[Matthias]

Is it possible to get access to a serialized object in form of a pointer to the begin of the serialized buffer and also to the total size of the buffer?

That would allow to use it within MPI programs to pass around instances of classes which can be serialized with cereal between different processes.

Boost contains a library (boost::mpi) which uses the boost::serialization library to achieve this functionality.

Thanks for help/info!
