So the functions would be like:

// present_pos is an std::vector<boost::uint8_t>::iterator to the 
// where the reading will start.
//
// dest_addr_ptr is where to write in memory
//
// length is how many bytes to read.
void read ( boost::uint8_t* dest_addr_ptr, boost::uint32_t const& length )
{
        if ( present_pos + length > data.end() )
        {
                // ERROR
        }

        memcpy ( dest_addr_ptr, *(*present_pos), length;
}

Was this what you had in mind?
