How to get client IP address?

[joe-average-user]

Hello,

I want to create an auth module for mosquitto that uses amongst other the client IP address. Is mosquitto->address the client IP (in some form (as string))?

Thank you!

mosquitto_client_address func

static int basic_auth_callback(int event, void *event_data, void *userdata)
{
struct mosquitto_evt_basic_auth *ed = event_data;
const char *ip_address;

UNUSED(event);
UNUSED(userdata);

ip_address = mosquitto_client_address(ed->client);
if(!strcmp(ip_address, "127.0.0.1")){
	/* Only allow connections from localhost */
	return MOSQ_ERR_SUCCESS;
}else{
	return MOSQ_ERR_AUTH;
}

}
