- Hello all,
-
- I have a NextStep application that occasionally goes into a (long) loop
- when a user asks the wrong query of its database. I have been asked
- to change this behaviour so that a control-c ejects the program from the
- loop, returning control to the main event loop.
-
- My question is, where do keyboard interrupts go, and how does a programmer
- detect and use them? The unix <signal.h> stuff doesn't work, NextStep or
- Mach or something obviously grabs signals uses them to its own ends.
-
- Is there a function in NextStep that is as conceptually easy as the
- signal.h stuff ? Better yet, which appkit object contains the
- [actNormallyUntillAControlcIsPressedThenSendMessageTo:myObject] method?
- Can I easily roll my own such method?
-
-
- Thanks in advance,
-
