## IDirectDrawClipper

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;
