Public bug reported:
I am using apollo broker, and mosquitto v 3.1 C client library to
interact with the broker. I am using a basic program to test the client
and the broker. While the program works nicely with qos 1, it does not
work with qos 0 and I cannot find the reason why it is not working with
qos 0. I am using a ubuntu 14.04LTS. Ill add the code that I am using
below. Please help me
#include<stdio.h>
#include<stdlib.h>
#include<mosquitto.h>
void on_publish(struct mosquitto *mosq, void *userdata, int mid)
{
printf("Inside publish callback");
mosquitto_disconnect(mosq);
}
int main(int argc, char *argv[])
{
struct mosquitto *mosq;
int err;
int err1;
mosq = mosquitto_new("unknown", true, NULL);
mosquitto_publish_callback_set(mosq, on_publish);
mosquitto_username_pw_set(mosq,"admin","password");
err=mosquitto_connect(mosq, "localhost", 61613,60);
if(err != 0 ){
printf("connect error= %s\n",mosquitto_strerror(err));
printf("error : %d\n",err1);
exit(0);
}
err1 = mosquitto_publish(mosq, NULL, "subject", 11, "Works", 1, true);
printf("Publish error = %s\n",mosquitto_strerror(err1));
mosquitto_loop_forever(mosq, -1, 1);
return 0;
}
