Is there any Cocoa and/or Carbon interface to UNIX signals?
Nope. It's pretty easy to set up a signal handler that can call back
to a Cocoa/CoreFoundation runloop though, by having it write to a pipe
or mach port which the runloop monitors.
However it's rarely useful to monitor signals in GUI apps, so you may
not want to actually do this.
Not to muddy the waters, but I believe that when NSExceptionHandler
refers to "system" or "system-level" exceptions, it's referring to
Mach exceptions and signals. The docs could be clearer, though.
Cheers,
Ken
