Detecting a full queue from a publisher object

[forestf255]

Does Iceoryx support either returning an error to the publisher or otherwise detecting when a subscribers queue is full? Neither the QoS policies documentation nor the BasePublisher API indicate this is possible, but wanted to make sure I am not missing anything. It seems like detecting overwritten/lost data is only visible from the subscriber

@forestf255 there is no API for that. The problem is that a publisher can have multiple subscriber and not all of the queues might be in the same state

@forestf255 We provide a publisher option to wait when a subscriber queue is full, see: https://github.com/eclipse-iceoryx/iceoryx/blob/master/iceoryx_examples/iceoptions/iox_publisher_with_options.cpp

Maybe this helps you to solve your problem.
