DDCAPS

The DDCAPS type represents the capabilities of the hardware exposed through the DirectDraw object. This type contains a DDSCAPS2 type used in this context to describe what kinds of DirectDrawSurface objects can be created. It might not be possible to simultaneously create all the surfaces described by these capabilities. This type is used with the DirectDraw7.GetCaps method.
