Hello! I'm new to proton (and AMQP), and have some questions about using the Messenger API in the C library to send messages to Windows Azure. I've noticed that it takes three steps before a message is actually sent (i.e. before it is fetched when running the 'recv' command line example). I call pn_messenger_put(), pn_messenger_send(), and then pn_messenger_stop(). My question is about the third call -- to pn_messenger_stop(). If I omit that and just call the first two, the message is not actually sent.
My concern is whether calling stop() after every send will be a problem in the case where I want to use the same instance of messenger to call recv() in a separate thread. The API docs state "A messenger cannot send or recv messages when it is stopped.". So, two questions: (1) Is the need to call stop() after each send() expected behavior? (2) Will repeatedly calling stop() affect the recv() running in the separate thread? Thank you! - Paul
