int GetClipBox(

HDC hdc,	// handle of the device context
LPRECT lprc	// address of structure with rectangle
);

Parameters

hdc: Identifies the device context.
lprc: Points to a RECT structure that is to receive the rectangle dimensions.

If the function succeeds, the return value specifies the clipping box’s complexity and can be any one of the following values:

Value	Meaning
NULLREGION	Region is empty.
