/// Start an asynchronous read.
/**
* This function is used to asynchronously read data from the stream handle.
* The function call always returns immediately.
*
* @param buffers One or more buffers into which the data will be read.
* Although the buffers object may be copied as necessary, ownership of the
* underlying memory blocks is retained by the caller, which must guarantee
* that they remain valid until the handler is called.
*
* @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(
* const boost::system::error_code& error, // Result of operation.
* std::size_t bytes_transferred // Number of bytes read.
* ); @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 The read operation may not read all of the requested number of bytes.
* Consider using the @ref async_read function if you need to ensure that the
* requested amount of data is read before the asynchronous operation
* completes.
*
* @par Example
* To read into a single data buffer use the @ref buffer function as follows:
* @code
* handle.async_read_some(boost::asio::buffer(data, size), handler);
* @endcode
* See the @ref buffer documentation for information on reading into multiple
* buffers in one go, and how to use it with arrays, boost::array or
* std::vector.
