Returns the color-capabilities information found in the VDDP description file for the adapter. Support for this nonmodal request is optional. However, if a miniport driver supports this request, it cannot return a subset of the color-capabilities information.
The miniport driver returns all VIDEO_COLOR_CAPABILITIES information in the VRP OutputBuffer.
If the miniport driver successfully returns the color-capabilities data, it sets the Information member of the STATUS_BLOCK structure to sizeof(VIDEO_COLOR_CAPABILITIES); otherwise, the miniport driver sets this member to zero.
