|
|
* #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. */
