I think very few applications outside those provided by the desktop
environment or the linux distribution actually cares about such
things. For desktop environments there is the concept of a "session"
and I suppose either the X Window System or each desktop environment
can signal somehow when it's about to end.

When a UNIX kernel has finished booting it will launch exactly one
user-space process, which is then supposed to launch everything else.
This is traditionally call "init", but upstart and systemd are fairly
recent and competing alternatives. The most canonical way for them to
signal system shutdown is to ask each process to terminate using a

An easier way forward may be if you can describe a bit more what the
end result you're trying to accomplish is. Perhaps the best way to
handle it is conceptually different than on Windows.
