I can't be certain that the cleanup function won't do other things
in the future, such as removing files (locks).
If, for some other reason, you need to act when the application
quits, you can register for the
NSApplicationWillTerminateNotification notification.

Hi,
Would the following NSApplication methods, placed into your
application delegate's code, help at all?
- (void)applicationDidFinishLaunching:(NSNotification
*)aNotification;
- (void)applicationWillTerminate:(NSNotification *)aNotification;
Of the latter, the docs say that one should "Put any necessary
cleanup code in this method."
Cheers,

I guess that would be the way to go. Although I'd have to either
expose a method that wraps around the C function, or call the C
function directly. Neither are really optimal, but the latter is a
lot better than nothing.
In case you use the notification, there is no need to expose anything.
You just register a method of your singleton to receive the
NSApplicationWillTerminateNotification and do your cleanup there.
On Apple's developer website there are several example projects that
make use of this. Here's one:

You need only look at the -init and the -applicationWillTerminate:
methods.
