Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

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