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

| 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.
