.SH ARGUMENTS
.IP \fId\fP 1i
Specifies the drawable.
.IP \fIdisplay\fP 1i
Specifies the connection to the X server.
.IP \fIgc\fP 1i
Specifies the GC.
.IP \fInrectangles\fP 1i
Specifies the number of rectangles in the array.
.IP \fIrectangles\fP 1i
Specifies an array of rectangles.
.IP \fIwidth\fP 1i
.br
.ns
.IP \fIheight\fP 1i
Specify the width and height, which specify the dimensions of the rectangle.
.IP \fIx\fP 1i
.br
.ns
.IP \fIy\fP 1i
Specify the x and y coordinates, which specify the upper-left corner of the rectangle.
.SH DESCRIPTION
The
.B XDrawRectangle
and
.B XDrawRectangles
functions draw the outlines of the specified rectangle or rectangles as
if a five-point
.B PolyLine
protocol request were specified for each rectangle:
.IP
[x,y] [x+width,y] [x+width,y+height] [x,y+height] [x,y]
.LP
For the specified rectangle or rectangles,
these functions do not draw a pixel more than once.
.B XDrawRectangles
draws the rectangles in the order listed in the array.
If rectangles intersect,
the intersecting pixels are drawn multiple times.
.LP
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.
.LP
.B XDrawRectangle
and
.B XDrawRectangles
can generate
.BR BadDrawable ,
.BR BadGC ,
and
.B BadMatch
errors.
.SH STRUCTURES
The
.B XRectangle
structure contains:
.LP
.EX
typedef struct {
short x, y;
unsigned short width, height;
} XRectangle;
.EE
.LP
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.
.SH DIAGNOSTICS
.TP 1i
.B BadDrawable
A value for a Drawable argument does not name a defined Window or Pixmap.
.TP 1i
.B BadGC
A value for a GContext argument does not name a defined GContext.
.TP 1i
.B BadMatch
An
.B InputOnly
window is used as a Drawable.
.TP 1i
.B BadMatch
Some argument or pair of arguments has the correct type and range but fails
to match in some other way required by the request.
