Here is an example program:

#include <boost/archive/binary_oarchive.hpp>
#include <boost/archive/binary_iarchive.hpp>
#include <boost/iostreams/stream_buffer.hpp>
#include <boost/iostreams/stream.hpp>
#include <boost/iostreams/device/back_inserter.hpp>
#include <boost/serialization/vector.hpp>
#include <vector>
#include <iostream>

int main()
{

   namespace io = boost::iostreams;
   typedef std::vector<char> buffer_type;
   buffer_type buffer;

   const std::vector<double> data(10000000);

   io::stream<io::back_insert_device<buffer_type> >  
output_stream(buffer);
   boost::archive::binary_oarchive oa(output_stream);

   oa << data;
   output_stream.flush();

   std::vector<double> data_in;

   io::basic_array_source<char> source(&buffer[0],buffer.size());
   io::stream<io::basic_array_source <char> > input_stream(source);
   boost::archive::binary_iarchive ia(input_stream);

   ia >> data_in;
}
