+/// Provides waitable timer functionality.
+/**
+ * The basic_deadline_timer class template provides the ability to perform a
+ * blocking or asynchronous wait for a timer to expire.
+ *
+ * Most applications will use the boost::asio::deadline_timer typedef.
+ *
+ * @par Thread Safety
+ * @e Distinct @e objects: Safe._at_n
+ * @e Shared @e objects: Unsafe.
+ *
+ * @par Examples
+ * Performing a blocking wait:
+ * @code
+ * // Construct a timer without setting an expiry time.
+ * boost::asio::deadline_timer timer(io_service);
+ *
+ * // Set an expiry time relative to now.
+ * timer.expires_from_now(boost::posix_time::seconds(5));
+ *
+ * // Wait for the timer to expire.
+ * timer.wait();
+ * @endcode
+ *
+ * @par
+ * Performing an asynchronous wait:
+ * @code
+ * void handler(const boost::system::error_code& error)
+ * {
+ * if (!error)
+ * {
+ * // Timer expired.
+ * }
+ * }
+ *
+ * ...
+ *
+ * // Construct a timer with an absolute expiry time.
+ * boost::asio::deadline_timer timer(io_service,
+ * boost::posix_time::time_from_string("2005-12-07 23:59:59.000"));
+ *
+ * // Start an asynchronous wait.
+ * timer.async_wait(handler);
+ * @endcode
+ *
+ * @par Changing an active deadline_timer's expiry time
+ *
+ * Changing the expiry time of a timer while there are pending asynchronous
+ * waits causes those wait operations to be cancelled. To ensure that the action
+ * associated with the timer is performed only once, use something like this:
+ * used:
+ *
+ * @code
+ * void on_some_event()
+ * {
+ * if (my_timer.expires_from_now(seconds(5)) > 0)
+ * {
+ * // We managed to cancel the timer. Start new asynchronous wait.
+ * my_timer.async_wait(on_timeout);
+ * }
+ * else
+ * {
+ * // Too late, timer has already expired!
+ * }
+ * }
+ *
+ * void on_timeout(const boost::system::error_code& e)
+ * {
+ * if (e != boost::asio::error::operation_aborted)
+ * {
+ * // Timer was not cancelled, take necessary action.
+ * }
+ * }
+ * @endcode
+ *
+ * @li The boost::asio::basic_deadline_timer::expires_from_now() function
+ * cancels any pending asynchronous waits, and returns the number of
+ * asynchronous waits that were cancelled. If it returns 0 then you were too
+ * late and the wait handler has already been executed, or will soon be
+ * executed. If it returns 1 then the wait handler was successfully cancelled.
+ *
+ * @li If a wait handler is cancelled, the boost::system::error_code passed to
+ * it contains the value boost::asio::error::operation_aborted.

+/** @defgroup buffer boost::asio::buffer
+ *
+ * @brief The boost::asio::buffer function is used to create a buffer object to
+ * represent raw memory, an array of POD elements, or a vector of POD elements.
+ *
+ * The simplest use case involves reading or writing a single buffer of a
+ * specified size:
+ *
+ * @code sock.write(boost::asio::buffer(data, size)); @endcode
+ *
+ * In the above example, the return value of boost::asio::buffer meets the
+ * requirements of the ConstBufferSequence concept so that it may be directly
+ * passed to the socket's write function. A buffer created for modifiable
+ * memory also meets the requirements of the MutableBufferSequence concept.
+ *
+ * An individual buffer may be created from a builtin array, std::vector or
+ * boost::array of POD elements. This helps prevent buffer overruns by
+ * automatically determining the size of the buffer:
+ *
+ * @code char d1[128];
+ * size_t bytes_transferred = sock.read(boost::asio::buffer(d1));
+ *
+ * std::vector<char> d2(128);
