IntersectRect info  Overview  Group

The IntersectRect function calculates the intersection of two source rectangles and places the coordinates of the intersection rectangle into the destination rectangle. If the source rectangles do not intersect, an empty rectangle (in which all coordinates are set to zero) is placed into the destination rectangle.

BOOL IntersectRect(

    LPRECT lprcDst,

// address of structure for intersection

    CONST RECT *lprcSrc1,

// address of structure with first rectangle

    CONST RECT *lprcSrc2 

// address of structure with second rectangle



Points to the RECT structure that is to receive the intersection of the rectangles pointed to by the lprcSrc1 and lprcSrc2 parameters.
Points to the RECT structure that contains the first source rectangle.
Points to the RECT structure that contains the second source rectangle.

Return Values

If the rectangles intersect, the return value is nonzero.

If the rectangles do not intersect, the return value is zero. To get extended error information, call GetLastError.
