Questions tagged [libmosquitto]

MQTT client library maintained by Eclipse IoT project. It is written in C language.

Read Eclipse Mosquitto project overview. This MQTT client library is developed as part of Eclipse IoT mosquitto project. The client header file mainly used is mosquitto.h(1)

  1. This library also has bindings in languages like C++(mosquittopp) and Python. Those bindings are also covered under this tag.
  2. This library is different from the client library provided by Eclipse Paho project and so queries related to Paho client and it's bindings( e.g. mqttpp ) should not use this tag.
