Why is the waitSet itself attached in this example?

[mangodan2003]

I've been using the below linked file as a basis for my project and am trying to better understand how the waitSet is being used.

Can somebody explain this?

https://github.com/eclipse-cyclonedds/cyclonedds/blob/master/examples/shm_throughput/shmsubscriber.c#L464

I gather one reason for doing this is to allow the application to "be woken up" from the blocking state of dds_waitset_wait() e.g. for shutdown, but this does not seem to be the case here, i.e. nowhere is dds_waitset_set_trigger() used.

I'd say your understanding is correct, which means I screwed up by overlooking that bit in https://github.com/eclipse-cyclonedds/cyclonedds/pull/101, and then this got propagated into shmsubscriber.c.

If you'd be willing to do a PR to remove this, that'd be great!

Sorry for the noise! I had some dummy/incorrect signoff details on my machine that I hadn't noticed until too late and wasn't sure how to deal with. Ended up scrubbing the branch and the original PR and starting over.
