What is the best way to find out if message was delivered to broker?
Hello,
I recently started to use libmosquitto in C program. I am writing publisher client and now I am looking for way to find out if message was actually delivered to broker (I use QOS=1). I found out what if broker connection was lost mosquitto_publish() still return MOSQ_ERR_SUCCESS (I suppose that's because mosquitto will send it after connection will resume). But I can't understand how my client can know is message was actually received by broker? The only way I found is log_callback() function is called when message was ACKed by broker. But in log_callback() I have only a text line like this:
"Client mosq/W0t6rA:
I don't think that to parse text is a good way to look for PUBACK for specified message ID. Is there better way to do that?
