Hi,
Thanks for reply. I read QA1340 which you mentioned & after going throught
it got following API:
*
IORegisterForSystemPower
Connects the caller to the Root Power Domain IOService for the purpose of
receiving Sleep, Wake, ShutDown, PowerUp notifications for the System.*
Even though I have not implemented the code, I think above API will work for
Shutdown & Restart. Am I correct?
Also then what should I use to trap logout event as did not find any info
regarding it in API reference?
& yes I am using same thing i.e. LSUIElement to hide dock icon but as I told
if I hide the dock icon then couldn't able to trap restart/shutdown/logout
using *workspaceWillPowerOff *cocoa notification. So finding other
alternative. As you have suggested to use QA1340, I will use
*IORegisterForSystemPower
*for trapping shutdown/restart.
Thanks again,
Palav
