Is there any maximum limit for maxBufferedMessages parameter or
it depends on the memory (INT_MAX in other words)?
Said U.
Hi Said,
it is implemented. There is a setting for the maximum number
of buffered messages:
https://www.eclipse.org/paho/files/mqttdoc/MQTTAsync/html/struct_m_q_t_t_async__create_options.html#a3b74acf6f315bb5fe36266bc9647ee97
Also, by checking the callback responses to publish, the
application can keep track of how many messages are still
outstanding, when the QoS > 0. (QoS 0 messages have no
responses so there is less feedback).

Hi Everybody,
I just want to be sure that C client has offline sending
feature (in Async client)? I saw comment that says " *
Ian Craggs - automatic reconnect and offline buffering (send
while disconnected) " on MQTTAsync.h, however I'm not
sure if it is implemented or feature enhancement. If offline
buffering implemented, are there any configuration available
to use in application (Setting the max number of messages that
will be stored offline etc.)?
