Asynchronous MQTT Client
An Asynchronous MQTT client library for C.© Copyright IBM Corp. 2009, 2013
An MQTT client application connects to MQTT-capable servers. A typical client is responsible for collecting information from a telemetry device and publishing the information to the server. It can also subscribe to topics, receive messages, and use this information to control the telemetry device.
MQTT clients implement the published MQTT v3 protocol. You can write your own API to the MQTT protocol using the programming language and platform of your choice. This can be time-consuming and error-prone.
To simplify writing MQTT client applications, this library encapsulates the MQTT v3 protocol for you. Using this library enables a fully functional MQTT client application to be written in a few lines of code. The information presented here documents the API provided by the Asynchronous MQTT Client library for C.
