bind executor to subscribe/publish

[owny990312]

I would like to ask, is there any way to make the subscribe callback run in the specified executor thread API.

In addition, is the listener object multi-threaded when listening to multiple subscribers? Is it possible to configure the number of threads?

@owny990312 I would not recommend to use the Listener at all. If you want to have explicit control over the thread you need to use the WaitSet instead.

Here it is possible to spawn a thread explicitly, maybe from you executor thread API, and handle all events directly.

Thank you for your response.
I notice that iceoryx2 seems to only have the waitset mechanism for handling subscription callbacks. During the use of waitset, I see that we need to use： ‘’auto notificationVector = waitset_raw_ptr->wait(); ‘ ’to block and wait for a subscription callback to be notified for execution. I'm wondering if this is thread-safe?

No API of iceoryx is thread-safe if it is not explicitly stated in the documentation. WaitSet::wait() cannot be called from multiple threads.

Thank you for your response.
