- Description
The TDx_DrawClipper::GetClipList method will retrieve a copy of this clipper's clip list.
Subsets of a clip list can be retrieved using the Rect parameter of this method to pass a rectangle which clips the clip list.

DDERR_GENERIC
DDERR_INVALIDCLIPLIST
DDERR_INVALIDOBJECT
DDERR_INVALIDPARAMS
DDERR_NOCLIPLIST
DDERR_REGIONTOOSMALL
- Parameters
Rect
The Rect parameter references a TRect for clipping the clip list.
Set this parameter to NULL to retrieve the whole clip list.
ClipList
The ClipList parameter references a RGNDATA structure for holding the clip list if this method returns successfully.
When this parameter is set to NULL the Size parameter of this method will be filled with the size, in bytes, of the entire clip list.
