I am working on an IOKit kext that would like to know the status of the
power adapter. That is specifically if the computer is running on
battery power or if it is plugged in. The kext has the potential for
running down the battery rapidly so we'd like to throttle the processing
if the computer is running on battery.
I've noticed a few things in the pwr_mgt folder but the documentation is
little thin on which functions to use and how it all goes together.
How does a kext get notified (or poll) the state of the power system as
it changes from battery to charger or charger to battery.
Thanks,
...Duane
