- * 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
- * asio::io_context::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
- * descriptor.async_read_some(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.
