Getting a segmentation fault when using mosquitto connect after using mosquitto_tls_set

        }

}

Am I doing something wrong here. I've checked all of my paths and tested them.

This looks ok, but without more details it is difficult to say. One comment - mosquitto_connect() will return 0 on success.
