Hi I'm part of the IBM team developing MQ Light ( https://www.ibmdw.net/messaging/mq-light/) and we are implementing our client API using the AMQP Messenger C API. Our client API has a connect function, which is required to be invoked before sending or receiving messages. The AMQP Messager C API does not seem to have an API function to perform a connect, without sending a message or subscribing to receive messages.
Looking at the messenger.c source code I found that function pn_messenger_resolve appears to give the connect behaviour we require. So could the pn_messenger_resolve be added to the API please (maybe with a different name, say: pn_messenger_connect, which seems more intuitive)? I was thinking that the pn_messenger_start function should eventually be doing the connect, but that does not take an address argument, so is probably not appropriate. I would also be interested in others opinions about this, as it may seem to be a strange thing to want to do, i.e. why would you want to connect if you're not going to send or receive messages? A use case for this could be that a server wants to be aware of active clients communicating with it before they are ready to send or receive messages. Also a connect function enables a client to determine if a server is available before exchanging data with it.
