[paho-dev] MQTTClient_publishMessage()'s in asynchronous mode

[Laurent FAILLIE <l_faillie@xxxxxxxxx>]

Hello,

I made several C daemons that are publishing dynamically allocated data. PAHO is used in asynchronous mode.

Is it safe to :

dt = malloc( ... );

MQTTClient_publishMessage( dt ),

free(dt)

If not, how can I ensure data are not anymore used ?

I firstly thought to wait for delivery completion using MQTTClient_deliveryComplete() but the documentation said it doesn't work with QoS0 ... which is my case.

Thanks

Laurent
