/* Notes to implementors:
* #1: The native implementation of these functions attempted to read in
* registry entries that I was unable to locate on any of the Windows
* machines I checked, but I only had desktops available, so maybe
* laptop users will have better luck. They return FNF errors because
* that's what the native DLL was returning during my tests.
* #2: These functions call NtPowerInformation but I don't know what they
* do with the results, and NtPowerInformation doesn't do much in WINE yet
* anyway.
* #3: Since I can't get several other functions working (see note #1),
* implementing these functions is going to have to wait until somebody can
* cobble together some sane test input. */
