I'm porting a unix command line app to be a Cocoa app. My program
opens a device (/dev/tty.usbserial) when it starts up, and closes it
when it exits. I haven't been able to figure out how to make this work
correctly when it's a Cocoa app.
Here's my main, generated by interface builder, with printouts added.
int main(int argc, char *argv[])
{
int retval;
printf("App starting\n");
retval = NSApplicationMain(argc, (const char **) argv);
printf("App exiting\n");
return retval;
}
When I run it, the first printout prints fine, and the app runs as
expected. The window comes up and works correctly. When the app exits,
(by closing it from the gui) the second printf never prints. If I put
a breakpoint there, it never hits. This is probably very basic, but..
what's going on here?
What is the correct way for me to execute some cleanup code when the
application exits?
Thanks,
Neil Baylis
