-/// Start an asynchronous operation to read data into a streambuf until a
-/// function object indicates a match.
-/**
- * This function is used to asynchronously read data into the specified
- * streambuf until a user-defined match condition function object, when applied
- * to the data contained in the streambuf, indicates a successful match. The
- * function call always returns immediately. The asynchronous operation will
- * continue until one of the following conditions is true:
- *
- * @li The match condition function object returns a std::pair where the second
- * element evaluates to true.
- *
- * @li An error occurred.
- *
- * This operation is implemented in terms of zero or more calls to the stream's
- * async_read_some function. If the match condition function object already
- * indicates a match, the operation completes immediately.
- *
- * @param s The stream from which the data is to be read. The type must support
- * the AsyncReadStream concept.
- *
- * @param b A streambuf object into which the data will be read.
- *
- * @param match_condition The function object to be called to determine whether
- * a match exists. The signature of the function object must be:
- * @code pair<iterator, bool> match_condition(iterator begin, iterator end);
- * @endcode
- * where @c iterator represents the type:
- * @code buffers_iterator<basic_streambuf<Allocator>::const_buffers_type>
- * @endcode
- * The iterator parameters @c begin and @c end define the range of bytes to be
- * scanned to determine whether there is a match. The @c first member of the
- * return value is an iterator marking one-past-the-end of the bytes that have
- * been consumed by the match function. This iterator is used to calculate the
- * @c begin parameter for any subsequent invocation of the match condition. The
- * @c second member of the return value is true if a match has been found, false
- * otherwise.
- *
- * @param handler The handler to be called when the read operation completes.
- * Copies will be made of the handler as required. The function signature of the
- * handler must be:
- * @code void handler(
- *   // Result of operation.
- *   const boost::system::error_code& error,
- *
- *   // The number of bytes in the streambuf's get
- *   // area that have been fully consumed by the
- *   // match function. O if an error occurred.
- *   std::size_t bytes_transferred
- * ); @endcode
- * Regardless of whether the asynchronous operation completes immediately or
- * not, the handler will not be invoked from within this function. Invocation of
- * the handler will be performed in a manner equivalent to using
- * boost::asio::io_service::post().
- *
- * @note After a successful async_read_until operation, the streambuf may
- * contain additional data beyond that which matched the function object. An
- * application will typically leave that data in the streambuf for a subsequent
- * async_read_until operation to examine.
- *
- * @note The default implementation of the @c is_match_condition type trait
- * evaluates to true for function pointers and function objects with a
- * @c result_type typedef. It must be specialised for other user-defined
- * function objects.
- *
- * @par Examples
- * To asynchronously read data into a streambuf until whitespace is encountered:
- * @code typedef boost::asio::buffers_iterator<
- *     boost::asio::streambuf::const_buffers_type> iterator;
- *
- * std::pair<iterator, bool>
- * match_whitespace(iterator begin, iterator end)
- * {
- *   iterator i = begin;
- *   while (i != end)
- *     if (std::isspace(*i++))
- *       return std::make_pair(i, true);
- *   return std::make_pair(i, false);
- * }
- * ...
- * void handler(const boost::system::error_code& e, std::size_t size);
- * ...
- * boost::asio::streambuf b;
- * boost::asio::async_read_until(s, b, match_whitespace, handler);
- * @endcode
- *
- * To asynchronously read data into a streambuf until a matching character is
- * found:
- * @code class match_char
- * {
- * public:
- *   explicit match_char(char c) : c_(c) {}
- *
- *   template <typename Iterator>
- *   std::pair<Iterator, bool> operator()(
- *       Iterator begin, Iterator end) const
- *   {
- *     Iterator i = begin;
- *     while (i != end)
- *       if (c_ == *i++)
- *         return std::make_pair(i, true);
- *     return std::make_pair(i, false);
- *   }
- *
- * private:
- *   char c_;
- * };

- * namespace asio {
- *   template <> struct is_match_condition<match_char>
- *     : public boost::true_type {};
- * } // namespace asio
- * ...
- * void handler(const boost::system::error_code& e, std::size_t size);
- * ...
- * boost::asio::streambuf b;
