XEmptyRegion(3X11) XLIB FUNCTIONS XEmptyRegion(3X11)NAMEXEmptyRegion, XEqualRegion, XPointInRegion, XRectInRegion - determine if regions are empty or equalSYNTAXBool 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;ARGUMENTSr Specifies the region. r1 r2 Specify the two regions. width height Specify the width and height, which define the rectangle. or the coordinates of the upper-left corner of the rectangle x y Specify the x and y coordinates, which define the point.DESCRIPTIONThe 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.SEE ALSOXCreateRegion(3X11), XIntersectRegion(3X11) Xlib - C Language X Interface X Version 11 Release 6.6 XEmptyRegion(3X11)
