You can access it just like you access std::streambuf. Look at the example:
http://www.boost.org/doc/libs/1_40_0/doc/html/boost_asio/reference/streambuf.html

Besides, you can use streambuf::data() member function to access the
character sequence directly. Look how it's done in
boost/asio/impl/read_util.ipp.
