+/// A channel for messages.
+/**
+ * The basic_channel class template is used for sending messages between
+ * different parts of the same application. A <em>message</em> is defined as a
+ * collection of arguments to be passed to a completion handler, and the set of
+ * messages supported by a channel is specified by its @c Traits and
+ * <tt>Signatures...</tt> template parameters. Messages may be sent and received
+ * using asynchronous or non-blocking synchronous operations.
+ *
+ * Unless customising the traits, applications will typically use the @c
+ * experimental::channel alias template. For example:
+ * @code void send_loop(int i, steady_timer& timer,
+ * channel<void(error_code, int)>& ch)
+ * {
+ * if (i < 10)
+ * {
+ * timer.expires_after(chrono::seconds(1));
+ * timer.async_wait(
+ * [i, &timer, &ch](error_code error)
+ * {
+ * if (!error)
+ * {
+ * ch.async_send(error_code(), i,
+ * [i, &timer, &ch](error_code error)
+ * {
+ * if (!error)
+ * {
+ * send_loop(i + 1, timer, ch);
+ * }
+ * });
+ * }
+ * });
+ * }
+ * else
+ * {
+ * ch.close();
+ * }
+ * }
+ *
+ * void receive_loop(channel<void(error_code, int)>& ch)
+ * {
+ * ch.async_receive(
+ * [&ch](error_code error, int i)
+ * {
+ * if (!error)
+ * {
+ * std::cout << "Received " << i << "\n";
+ * receive_loop(ch);
+ * }
+ * });
+ * } @endcode
+ *
+ * @par Thread Safety
+ * @e Distinct @e objects: Safe.@n
+ * @e Shared @e objects: Unsafe.
+ *
+ * The basic_channel class template is not thread-safe, and would typically be
+ * used for passing messages between application code that runs on the same
+ * thread or in the same strand. Consider using @ref basic_concurrent_channel,
+ * and its alias template @c experimental::concurrent_channel, to pass messages
+ * between code running in different threads.

+/// Creates an initiation function object that may be used to launch a
+/// coroutine-based composed asynchronous operation.
+/**
+ * The experimental::co_composed utility simplifies the implementation of
+ * composed asynchronous operations by automatically adapting a coroutine to be
+ * an initiation function object for use with @c async_initiate. When awaiting
+ * asynchronous operations, the coroutine automatically uses a conforming
+ * intermediate completion handler.
+ *
+ * @param implementation A function object that contains the coroutine-based
+ * implementation of the composed asynchronous operation. The first argument to
+ * the function object represents the state of the operation, and may be used
+ * to test for cancellation. The remaining arguments are those passed to @c
+ * async_initiate after the completion token.
+ *
+ * @param io_objects_or_executors Zero or more I/O objects or I/O executors for
+ * which outstanding work must be maintained while the operation is incomplete.
+ *
+ * @par Per-Operation Cancellation
+ * By default, terminal per-operation cancellation is enabled for composed
+ * operations that use experimental::co_composed. To disable cancellation for
+ * the composed operation, or to alter its supported cancellation types, call
+ * the state's @c reset_cancellation_state function.
+ *
+ * @par Examples
+ * The following example illustrates manual error handling and explicit checks
+ * for cancellation. The completion handler is invoked via a @c co_yield to the
+ * state's @c complete function, which never returns.
+ *
+ * @code template <typename CompletionToken>
+ * auto async_echo(tcp::socket& socket,
+ * CompletionToken&& token)
+ * {
+ * return asio::async_initiate<
+ * CompletionToken, void(std::error_code)>(
+ * asio::experimental::co_composed(
+ * [](auto state, tcp::socket& socket) -> void
+ * {
+ * state.reset_cancellation_state(
+ * asio::enable_terminal_cancellation());
+ *
+ * while (!state.cancelled())
+ * {
+ * char data[1024];
+ * auto [e1, n1] =
+ * co_await socket.async_read_some(
+ * asio::buffer(data),
+ * asio::as_tuple(asio::deferred));
+ *
+ * if (e1)
+ * co_yield state.complete(e1);
+ *
+ * if (!!state.cancelled())
+ * co_yield state.complete(
+ * make_error_code(asio::error::operation_aborted));
+ *
+ * auto [e2, n2] =
+ * co_await asio::async_write(socket,
+ * asio::buffer(data, n1),
+ * asio::as_tuple(asio::deferred));
+ *
+ * if (e2)
+ * co_yield state.complete(e2);
+ * }
+ * }, socket),
+ * token, std::ref(socket));
+ * } @endcode
+ *
+ * This next example shows exception-based error handling and implicit checks
+ * for cancellation. The completion handler is invoked after returning from the
+ * coroutine via @c co_return. Valid @c co_return values are specified using
+ * completion signatures passed to the @c co_composed function.
+ *
+ * @code template <typename CompletionToken>
+ * auto async_echo(tcp::socket& socket,
+ * CompletionToken&& token)
+ * {
+ * return asio::async_initiate<
+ * CompletionToken, void(std::error_code)>(
+ * asio::experimental::co_composed<
+ * void(std::error_code)>(
+ * [](auto state, tcp::socket& socket) -> void
+ * {
+ * try
+ * {
+ * state.throw_if_cancelled(true);
+ * state.reset_cancellation_state(
+ * asio::enable_terminal_cancellation());
+ *
+ * for (;;)
+ * {
+ * char data[1024];
+ * std::size_t n = co_await socket.async_read_some(

-/** @defgroup asio_handler_invoke asio::asio_handler_invoke
- *
- * @brief Default invoke function for handlers.
- *
- * Completion handlers for asynchronous operations are invoked by the
- * io_context associated with the corresponding object (e.g. a socket or
- * deadline_timer). Certain guarantees are made on when the handler may be
- * invoked, in particular that a handler can only be invoked from a thread that
- * is currently calling @c run() on the corresponding io_context object.
- * Handlers may subsequently be invoked through other objects (such as
- * io_context::strand objects) that provide additional guarantees.
- *
- * When asynchronous operations are composed from other asynchronous
- * operations, all intermediate handlers should be invoked using the same
- * method as the final handler. This is required to ensure that user-defined
- * objects are not accessed in a way that may violate the guarantees. This
- * hooking function ensures that the invoked method used for the final handler
- * is accessible at each intermediate step.
- *
- * Implement asio_handler_invoke for your own handlers to specify a custom
- * invocation strategy.
- *
- * This default implementation invokes the function object like so:
- * @code function(); @endcode
- * If necessary, the default implementation makes a copy of the function object
- * so that the non-const operator() can be used.
- *
- * @par Example
- * @code
- * class my_handler;
- *
- * template <typename Function>
- * void asio_handler_invoke(Function function, my_handler* context)
- * {
- * context->strand_.dispatch(function);
- * }
- * @endcode

-/**
- * The signal_set class provides the ability to perform an asynchronous wait
- * for one or more signals to occur.
- *
- * @par Thread Safety
- * @e Distinct @e objects: Safe.@n
- * @e Shared @e objects: Unsafe.
- *
- * @par Example
- * Performing an asynchronous wait:
- * @code
- * void handler(
- * const asio::error_code& error,
- * int signal_number)
- * {
- * if (!error)
- * {
- * // A signal occurred.
- * }
- * }
- *
- * ...
- *
- * // Construct a signal set registered for process termination.
- * asio::signal_set signals(io_context, SIGINT, SIGTERM);
- *
- * // Start an asynchronous wait for one of the signals to occur.
- * signals.async_wait(handler);
- * @endcode
- *
- * @par Queueing of signal notifications
- *
- * If a signal is registered with a signal_set, and the signal occurs when
- * there are no waiting handlers, then the signal notification is queued. The
- * next async_wait operation on that signal_set will dequeue the notification.
- * If multiple notifications are queued, subsequent async_wait operations
- * dequeue them one at a time. Signal notifications are dequeued in order of
- * ascending signal number.
- *
- * If a signal number is removed from a signal_set (using the @c remove or @c
- * erase member functions) then any queued notifications for that signal are
- * discarded.
- *
- * @par Multiple registration of signals
- *
- * The same signal number may be registered with different signal_set objects.
- * When the signal occurs, one handler is called for each signal_set object.
- *
- * Note that multiple registration only works for signals that are registered
- * using Asio. The application must not also register a signal handler using
- * functions such as @c signal() or @c sigaction().
- *
- * @par Signal masking on POSIX platforms
- *
- * POSIX allows signals to be blocked using functions such as @c sigprocmask()
- * and @c pthread_sigmask(). For signals to be delivered, programs must ensure
- * that any signals registered using signal_set objects are unblocked in at
- * least one thread.
