What happen to a msg Qos >0 with the Asyncclient if you do not receive the PUBACK ?

[Pascal-Fremaux]

I am not capable to really understand what happen to a message QoS>0, sent previously, but with no reception of the PUBACK ever.

Seems the msg stay in the client->outboundMsgs, and might be republished on some conditions (unclear?)

The queue seems to be freed on the client free : could you confirm ? Can it be freed by other trigger (close session?)

Is there any way to cancel (ListRemove(client->outboundMsgs)) a particular previous "sent" message that did not yet receive its PUBACK after some time during a session to avoid reemission ?

Coud I remove all the messages not acked on a close session ? Or do I have to free the client ?
