Interacting with systemd services programmatically in c++ about sdbus-cpp

[sangelovic]

AFAIK, systemctl transforms these command line actions into D-Bus calls to the org.freedesktop.systemd1 service, which exports /org/freedesktop/systemd1 object with a number of D-Bus methods, properties and signals. You are probably asking whether you can create a proxy to that systemd1 object by using sdbus-c++ in your application. From what I have seen, I don't see any reason for that to be undoable. It should be perfectly possible. Probably the best way is to use D-Bus introspection to introspect systemd1 object interface definition, the result of which will be an XML interface description. Then out of this description, you can use sdbus-c++-xml2cpp generator to generate adaptor (you don't need that) and proxy classes. Then simply instantiate a proxy (see using-c++ tutorial for how to do that, or for example look at sdbus-c++ perf tests proxy) and you can issue calls against systemd1 and receive signals from it.

Thank you. That worked perfectly!
