I don't understand.

IntersectRect returns the intersection of the 2 rectangles R1 and R2 in Rect. It returns True if the 2 rectangles have an intersection, otherwise False is returned, and Rect is filled with zero.

The explanation is clear. 2nd and 3rd parameter is intersected and the resulting intersection rect is placed in 1st parameter.
