I have written battery driver and that driver sends an uevent when a power supply is changed, i.e. from AC to battery
When I run udevadm monitor I see an KERNEL and UDEVCHANGE events from power_supply subsystem upon removing AC supply.
My requirement is to notify the user application when there is an CHANGE event from power_supply subsystem. I do not want to poll for kernel message or netlink socket from user application.
Is it possible for me to register/listen for this particular
ueventfrom user application and gets something like callback function whenan event occurs?
