Paho C Client

The Paho C Client is a software library that allows programs written in C to communicate using the MQTT protocol, which is designed for lightweight, real-time messaging between devices. It enables devices and applications to send ("publish") and receive ("subscribe") messages efficiently over networks, such as sensors reporting data or control systems managing devices. By providing standardized tools, Paho C simplifies the development of reliable, scalable, and efficient messaging systems, especially in Internet of Things (IoT) environments, where multiple devices need to communicate seamlessly and with minimal resources.
