Kindly where the documentation for the constructer Mosquitto("some string here")

what does the parameter for that constructor mean? because in the mqtt for paho project, the constructor takes 4 parameters, and the one that is close to your case is the client id. Thus, do you represent your client s using that kind of contacination ?
