IOCTL_VIDEO_QUERY_COLOR_CAPABILITIES IOCTL

Description

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.

Parameters

Major code

Input buffer

None

Input buffer length

Output buffer

The miniport driver returns all VIDEO_COLOR_CAPABILITIES information in the VRP OutputBuffer.

Output buffer length

Input/output buffer

Input/output buffer length

Status block

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.
