Qpid C++ session.release behavior

[msharee9 <ms...@gmail.com>]

Hi 

A quick question abiut the release method. The API doc says that the broker
MAY redeliver a released message. Does this mean the message is not
guaranteed to be redelivered? 

What is the behavior of broker in case of multiple consumers trying to fetch
from the same queue when broker redelivers a released message from one of
the consumers?

That depends on the broker being used.

For the c++ broker, at present it will always be delivered. In theory it 
could eventually decide to dead-letter the message, but in practice the 
c++ broker does not do that at this time.

Again that depends on the broker being used. The c++ broker will 
effectively return the message to the queue to be consumed by any of the 
currently active consumers.
