CRectIntersection

Calculates the intersection of two CRects.

Synopsis

CRect * CRectIntersection (CRect *dst, CRect *rect1, CRect *rect2)

If there is no common area between the two source rectangles, the function return value is NULL, but the values in *dst are still modified.

Arguments

dst: Pointer to a CRect where the results are to be stored.

rect1: Pointer to one of the source CRects.

rect2: Pointer to the other source CRect.

Return Value

Returns dst, or NULL if there is no common area between the source rectangles.

Implementation
