Hi Richard,
Sorry, I thought you were looking for code to catch the wakeup rather than
the power off.
BTW - the code I posted only works if your app was the active app at power
off - that's what the "if (sysAppLaunchFlagSubCall & launchFlags): check is
for. If the sub call flag is enabled it means you are the active app.
Regards,
Bob
