The DD_SETCOLORKEYDATA structure is passed to the DirectDraw hardware interface’s SetColorKey surface object callback.

Members

lpDD

Pointer to the DD_DIRECTDRAW_GLOBAL structure that describes the driver.

lpDDSurface

Pointer to the DD_SURFACE_LOCAL structure that describes the surface whose color key is to be set.

dwFlags

Specifies how the driver should handle the color key. This field can be a combination of the following values:

Value	Meaning
DDCKEY_SRCBLT	Specifies the default source color key for Blt operations.
DDCKEY_DESTBLT	Specifies the default destination color key for Blt operations.
DDCKEY_SRCOVERLAY	Specifies the source color key for the overlay.
DDCKEY_DESTOVERLAY	Specifies the destination color key for the overlay.

ckNew

Specifies the DD_COLORKEY structure that describes the color key.

ddRVal

Location in which the driver returns a DirectDraw status return code. The status codes are defined in ddraw.h.

SetColorKey

Unused by Windows NT.
