Re: how to exit()

[Tilo Christ]

Hi!
Try setjmp/longjmp at and to the point you'd like to be your exit point.
I did that with the Palm macros for exception handling. My 
main routine looks like this:

static UInt32 StarterPalmMain(UInt16 cmd, void */*cmdPBP*/, 
UInt16 launchFlags)
{
	if (cmd == sysAppLaunchCmdNormalLaunch)
	{
        // The execution of the application is enclosed by 
the OS try/catch mechanism.
        // This allows exiting the application from 
anywhere (e.g. Device::panic).
        ErrTry
        {
    		Err error = AppStart(launchFlags);
    		if (error != errNone)
    			return error;
    				
    		FrmGotoForm(MainForm);
    		AppEventLoop();
        }
        ErrCatch(inErr)
        {
            // Application failure. Cleanup work will be 
done by AppStop later.
        } ErrEndCatch

		AppStop();

                return errNone;
        }
        else
        {
                return errNone;
        }
}
If I want to exit the application I do this:
void Device::panic(const Char *message)
{
    FrmCustomAlert(DevicePanicAlert, message, NULL, NULL);
    ErrThrow(0L);
}
Hope this helps,
Tilo

You can always post a appstop event...  but it wont stop the application in
it's tracks.

Let's say my program recognizes a (relatively) catastrophic state in 
which I want to just display an error message and exit. Is there an 
equivalent to exit() that I could call that would stop execution from 
where ever I call it?

Thanks,
matt
