How I can call funtions callback into a Class

[GiovaniSchreiber]

I am trying to call the function "callback" into a Class, but it not work.

PubSubClientTools *clientMQTT;

......
clientMQTT->subscribe(TOPICO_SUBSCRIBE_CM_LAMP, MQTTClass::subscriber);//the problem is here
//clientMQTT->subscribe(TOPICO_SUBSCRIBE_CM_LAMP, std::bind(&MQTTClass::subscriber, this);//not work too
..........
void MQTTClass::subscriber(String topic, String message) {
MQTT_Call_buttonPress(bool(message), MQTT_S);
}
Does anyone know how I do it?

This library already does it in the .h file, just implement something similar in your own code:

ArduinoPubSubClientTools/PubSubClientTools.h

Line 41 in bd93920

std::function<void(PUBSUBCLIENT_CALLBACK_PARAMETERS)> mqtt_callback = std::bind(&PubSubClientTools::callback, this, std::placeholders::_1, std::placeholders::_2, std::placeholders::_3);

Afaik the std::* things are only available on ESP8266, not AVR platform.
