BOOL IntersectRect( LPCRECT lpRect1, LPCRECT lpRect2 );
Return Value
Nonzero if the intersection is not empty; 0 if the intersection is empty.
Parameters
lpRect1
Points to a RECT structure or CRect object that contains a source rectangle.
lpRect2
Points to a RECT structure or CRect object that contains a source rectangle.
Remarks
Makes a CRect equal to the intersection of two existing rectangles. The intersection is the largest rectangle contained in both existing rectangles.
Note Both of the rectangles must be normalized or this function may fail. You can call NormalizeRect to normalize the rectangles before calling this function.
