Proton-C - how to acknowledge received messages?

Dear protons,

I am using Proton-C to read amqp messages and I wonder why there is no
acknowledge call in the messenger.

In the Qpid C++ Messaging API there is an acknowledge() call in the Session
class.

I assume that the ack is going to the message broker. If this is the case
then I ask myself why there is no ack call in Proton.

Can anyone enlighten me?

Regards,
Raphael

You should be able to call pn_messenger_accept(...) or
messenger.accpet(...) on the tracker of the message depending on what
flavor of the API you are using. In python, the tracker is returned when
you call get(...) in C you can access the tracker for the most recently
received message by using pn_messenger_incoming_tracker(...).
