XEmptyRegion(3X11)       XLIB FUNCTIONS        XEmptyRegion(3X11)


     XEmptyRegion, XEqualRegion, XPointInRegion, XRectInRegion -
     determine if regions are empty or equal


     Bool XEmptyRegion(Region r);

     Bool XEqualRegion(Region r1, Region r2);

     Bool XPointInRegion(Region r, int x, int y);

     int XRectInRegion(Region r, int x, int y, unsigned int
          width, unsigned int height);


     r         Specifies the region.

     r2        Specify the two regions.

     height    Specify the width and height, which define the
               rectangle. or the coordinates of the upper-left
               corner of the rectangle

     y         Specify the x and y coordinates, which define the


     The XEmptyRegion function returns True if the region is

     The XEqualRegion function returns True if the two regions
     have the same offset, size, and shape.

     The XPointInRegion function returns True if the point (x, y)
     is contained in the region r.

     The XRectInRegion function returns RectangleIn if the rec-
     tangle is entirely in the specified region, RectangleOut if
     the rectangle is entirely out of the specified region, and
     RectanglePart if the rectangle is partially in the specified
