To be completely clear about this, these leaked ports are not reclaimed when the application exits?

Mach will clean them up for you at task termination. However, whenever you don't need the resource, you should do the proper thing to release it.



Thank you for the clarification. It seems to me that the example should be changed to simply _exit(2) since the ports will be cleaned up.

The problem is that someone will copy the example into a library routine and replace the _exit() with a return. Then they wonder why they leak - since Apple provided the example and it should have managed its resources.

That's a good point. Maybe the signal handler could be changed (and maybe catch SIGQUIT as well) to stop the run loop and then clean up after the run loop has terminated. But then, that might just confuse the issue.


Actually, a comment just after the run loop would probably be best saying that in actual use the clean up code needs to be called.
