Calculates the intersection of two CRects.

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

Calculates the intersection of two rectangles, returning a rectangle that describes the common area. The destination rectangle (dst) can be the same as either source rectangle. 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.

• 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.

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