But that makes sense, since the launcher is also the master list of PQAs. :-)
Anyway, if you want to 'exit' an app by launching the launcher, that's
pretty easy, just call UIAppSwitch and specify the launcher.
Of course, you still have to run your own event loop until you get the
appStopEvent, so it's no help for the original poster's question which was
'how do I bail out in the case of an error?'
How the built-in apps bail out in the case of an error is with
ErrFatalDisplay or ErrFatalDisplayIf. These offer the only 'true' error
recovery, which is to reset the device. Just exiting your app won't help
if you've made a truly bad error, because you'll probably have trashed the
heap so the next app to run will crash instead. ...so you may as well just
tell the user and let them reset.
