[publisher] [endsect] [section:receiver The receiver] This example shows how to use __Client__ as a receiver. The __Client__ subscribes and indefinitely receives Application Messages from the Broker. [receiver] [endsect] [section:multiflight_client The multiflight Client] This example shows how to use __Client__ to simultaneously dispatch multiple requests. [multiflight_client] [endsect] [section:timeout_with_parallel_group Timed MQTT operations with parallel group] This example demonstrates how to use the __Client__ with its support for per-operation cancellation to perform operations under a time constraint using parallel group. Specifically, in this example, the __Client__ will subscribe to a Topic and try to receive a message from the Topic within `5 seconds`. [timeout_with_parallel_group] [endsect] [section:timeout_with_awaitable_operators Timed MQTT operations with awaitable operators] This example demonstrates how to use the __Client__ with its support for per-operation cancellation to perform operations under a time constraint using awaitable operators. Specifically, in this example, a call to [refmem mqtt_client async_publish] and [refmem mqtt_client async_disconnect] must complete within `5 seconds`. Otherwise, they will be cancelled. [timeout_with_awaitable_operators] [endsect] [section:hello_world_in_multithreaded_env Hello World in a multithreaded environment using callbacks] This example demonstrates how to publish a "Hello World" message in a multithreaded environment using callbacks (`post`/`dispatch`). [hello_world_in_multithreaded_env] [endsect] [section:hello_world_in_coro_multithreaded_env Hello World in a multithreaded environment using coroutines] This example demonstrates how to publish a "Hello World" message in a multithreaded environment using coroutines (`co_spawn`).
