Power aware application
I am working to develop software for a Set top box with GIT Linux.
I need to implement power management feature.
I have added the routines in the kernel with which the system can enter suspend when I give the following system call from the application
system("echo standby > /sys/power/state")
My question is how to have a callback in the user level application which will come to know that the system has resumed after suspend?
Can I pass a user level function to the register_pm_notifier api...or is ther any other way out
