Description

Call IntersectRect to obtain the rectangle that is the intersection of R1 and R2. The intersection is returned as the Rect parameter.

IntersectRect returns true if the two rectangles have a nonempty intersection. If R1 and R2 do not overlap, IntersectRect returns false, and the Rect parameter is set to a rectangle at position (0,0) with 0 Width and 0 Height.
