XEmptyRegion(3X11)														XEmptyRegion(3X11)

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

SYNOPSIS
       Bool XEmptyRegion(r)
	       Region r;

       Bool XEqualRegion(r1, r2)
	       Region r1, r2;

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

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

ARGUMENTS
       Specifies  the  region.	 Specify  the two regions.  Specify the width and height, which define the rectangle.  Specify the x and y coordi-
       nates, which define the point or the coordinates of the upper-left corner of the rectangle.

DESCRIPTION
       The XEmptyRegion function returns True if the region is empty.

       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 rectangle 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 region.
