Applications use the methods of the IDirectDrawClipper interface to manage clip lists. This section is a reference to the methods of this interface. For a conceptual overview, see Clippers.
The methods of the IDirectDrawClipper interface can be organized into the following groups:
| Allocating memory | Initialize |
| Clip list | GetClipList |
| IsClipListChanged | |
| SetClipList | |
| SetHWnd | |
| Handles | GetHWnd |
The IDirectDrawClipper interface, like all COM interfaces, inherits the IUnknown interface methods. The IUnknown interface supports the following three methods:
| AddRef | |
| QueryInterface | |
| Release |
You can use the LPDIRECTDRAWCLIPPER data type to declare a variable that contains a pointer to an IDirectDrawClipper interface. The Ddraw.h header file declares these data types with the following code:
typedef struct IDirectDrawClipper FAR *LPDIRECTDRAWCLIPPER;
