[systemd-devel] sd-bus signal callback return value

[Daan De Meyer]

Hi,

I've opened a pull request to clarify the return values of the callbacks
and their effect: https://github.com/systemd/systemd/pull/15253. It's not
complete yet but the idea is to add answers for all your questions to the
docs.

Regards,

Daan
