VioGetConfig(ConfigID, ConfigData, VioHandle)

Parameters

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

Remarks

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.
