Specifies the drawable.
Specifies the connection to the X server.
Specifies the GC.
Specifies the number of rectangles in the array.
Specifies an array of rectangles.
Specify the width and height, which specify the dimensions of the rectangle.
Specify the x and y coordinates, which specify the upper-left corner of the rectangle.
[x,y] [x+width,y] [x+width,y+height] [x,y+height] [x,y]
For the specified rectangle or rectangles, these functions do not draw a pixel more than once. XDrawRectangles draws the rectangles in the order listed in the array. If rectangles intersect, the intersecting pixels are drawn multiple times.
Both functions use these GC components: function, plane-mask, line-width, line-style, cap-style, join-style, fill-style, subwindow-mode, clip-x-origin, clip-y-origin, and clip-mask. They also use these GC mode-dependent components: foreground, background, tile, stipple, tile-stipple-x-origin, tile-stipple-y-origin, dash-offset, and dash-list.
XDrawRectangle and XDrawRectangles can generate BadDrawable, BadGC, and BadMatch errors.

typedef struct {
short x, y;
unsigned short width, height;
} XRectangle;
All x and y members are signed integers. The width and height members are 16-bit unsigned integers. You should be careful not to generate coordinates and sizes out of the 16-bit ranges, because the protocol only has 16-bit fields for these values.
