That's not a 'nice way', as requested in the subject. :)
The nice way is to send a quit AppleEvent, which you can do like so:
static OSStatus SendQuitAppleEventToProcess (ProcessSerialNumber psn)
{
OSStatus err = paramErr;
NSAppleEventDescriptor* applicationDesc = [NSAppleEventDescriptor
descriptorWithDescriptorType:typeProcessSerialNumber
bytes:&psn
length:sizeof(psn)];
if (applicationDesc) {
NSAppleEventDescriptor* quitAppAppleEvent =
[NSAppleEventDescriptor
appleEventWithEventClass:kCoreEventClass
eventID:kAEQuitApplication
targetDescriptor:applicationDesc
returnID:kAutoGenerateReturnID
transactionID:kAnyTransactionID];
AppleEvent* quitApplicationAppleEventPtr =
(AEDesc*)[quitAppAppleEvent
aeDesc];
if (quitApplicationAppleEventPtr) {
AppleEvent replyEvent;
err = AESendMessage (quitApplicationAppleEventPtr,
&replyEvent,
kAEWaitReply, kAEDefaultTimeout);
if (!err) {
AEDisposeDesc (&replyEvent);
}
}
}
return err;
}
You can usually get a psn event for 'background apps'. See
GetProcessForPID(). There's also KillProcess() if it does not respond
to the quit event.
