Returns the video display configuration.

VioGetConfig(ConfigID, ConfigData, VioHandle)

ConfigID (ULONG) - input: Configuration ID.; Identifies the display configuration for which information is being requested:

Value Definition
   0  Current configuration
   1  Primary configuration
   2  Secondary configuration

ConfigData (PVIOCONFIGINFO) - output: Pointer to the configuration data.
VioHandle (HVIO) - input: Presentation-space handle.; This must be 0, unless the caller is a Presentation Manager application; in this case, it must be the value returned by VioCreatePS.

The values returned might not be correct if the adapter cannot be properly identified or if the device is not capable of returning its settings.
