You need a boost::interprocess::file_mapping and a 
boost::interprocess::mapped_region. The example at your link above 
should be enough to get you going.

I've found boost::iostreams::mapped_file[_source/_sink] to be a little 
more straightforward, and it directly supports using 
boost::filesystem::paths. See:
