IOPMKeys.h

Overview

This header defines C strings for use in accessing power management data. Note that all of these C strings must be converted to CFStrings before use. You can wrap them with the CFSTR() macro, or create a CFStringRef (that you must later CFRelease()) using CFStringCreateWithCString().

For additional information about power management for device drivers, see I/O Kit Fundamentals and Writing an I/O Kit Device Driver.
