Provide an API for the session handling

[ManuelSchneid3r]

I want to code an application that is able to poweroff, reboot, logout, lock, suspend etc. without a prompt. Using system commands like systemctl, reboot or poweroff need either su rights or kill the session ungraciously leaving applications no time to save their state.

Closing this 11 years later as not planned. Don't think it's going to happen.

Llms tell me there is cinnamon-session-quit --logout --no-prompt. Is this working?
