Qpid Proton vs Qpid C++

[Jose Alberto Fernandez Parejo <ja...@indra.es>]

Hello All,

We have to connect a C application to an AMQP1.0 peer (rabbitmq and
other gateway using AMQP1.0).

We plan to create a simple interface with basic oriented connection
primitives (open, connect, send, received, close,...) in order to be
easy to change the current SW to connect to AMQP connection.

We have installed and make tests with qpid proton and qpi c++.
For qpid c++ we have seen a basic correspondence with what we intent to do :
(1) Establishes the connection
(2) Creates a session
(3) Creates a receiver
(4) Creates a sender that sends
(5) Receives the message
(6) Closes the connection

But for qpid proton, this basic correspondence cannot be set

Since qpid c++ needs qpid proton for AMQP1.0 support. We are wondering
if, qpid proton has this basic primitive correspondence?

what are the C/C++ API differences between qpid proton and qpid c++?

Thanks for your support.

Regards

Not sure exactly what you mean there but you can certainly do all of 
those things with the proton c++ API. In fact you can probably use the 
simple_recv.cpp example as is and run it against rabbitmq.

The biggest difference really is one of API style. The proton c++ api is 
event driven, the qpid::messaging API is more synchronous, with library 
controlled IO thread(s) distinct from the applictaion thread.
