RabbitMQ C/C++ Async Publisher Confirm

[U MK]

Hi,

Is there any way to achieve the asynchronous Publisher confirm( i.e. Published receive ack asynchronously once subscriber read message from Queue) in RabbitMQ C/C++ library.

In RabbitMQ tutorial there is a an example for Publisher confirm asynchronously https://www.rabbitmq.com/tutorials/tutorial-seven-dotnet.html

I wanted similar example to achieve in C++, Can some one suggest me how I can achieve in C/C++ windows

Thanks,

Mohan

Hello

You could refer the documentation defined here:
https://github.com/CopernicaMarketingSoftware/AMQP-CPP

* Publish a message to an exchange
*
* You have to supply the name of an exchange and a routing key.
RabbitMQ will
* then try to send the message to one or more queues. With the
optional flags
* parameter you can specify what should happen if the message could
not be routed
* to a queue. By default, unroutable message are silently discarded.
*
* This method returns a reference to a DeferredPublisher object. You
can use
* this returned object to install callbacks that are called when an
undeliverable
* message is returned, or to set the callback that is called when the
server
* confirms that the message was received.
*
* To enable handling returned messages, or to enable
publisher-confirms, you must
* not only set the callback, but also pass in appropriate flags to
enable this
* feature. If you do not pass in these flags, your callbacks will not
be called.
* If you are not at all interested in returned messages or
publish-confirms, you
* can ignore the flag and the returned object.

Hi, 

Thanks for your reply.

I have this AMQP-CPP library, In which sample code it demonstrate the async publisher confirm.

I am using C code in VS2008, it wont support latest C++11 features, Is C++11 support is must for RabbitMQ.

Hi,

I am using reference library, https://github.com/alanxz/rabbitmq-c

Because our existing application build on VS 2008, which doesn't use C++11 feature.

Can you please guide in plane C RabbitMQ how to get async publisher confirm.

Thanks,

Mohan

Hi,

I have doubt, in AMQP-CPP 

Publisher confirm means ?

     1) When publisher publish the message to broker, broker confirms to publisher that I have received and processed 

              OR

     2) When publisher publish message to broker, broker confirms to Publisher  that consumer consume the message and deleted from queue.

Which statement is true?

I want to achieve the 2nd statement. by using publisher confirm is it possible to achieve?

Thanks,

Mohan
