SYNTAX

       int XDrawRectangle(Display *display, Drawable d, GC gc, int x, int y,
              unsigned int width, unsigned int height);

       int XDrawRectangles(Display *display, Drawable d, GC gc, XRectangle
              rectangles[], int nrectangles);

ARGUMENTS

       d         Specifies the drawable.

       display   Specifies the connection to the X server.

       gc        Specifies the GC.

       nrectangles
                 Specifies the number of rectangles in the array.

       rectangles
                 Specifies an array of rectangles.

       width
       height    Specify the width and height, which specify the dimensions of
                 the rectangle.

       x
       y         Specify the x and y coordinates, which specify the upper-left
                 corner of the rectangle.

DESCRIPTION

       The XDrawRectangle and XDrawRectangles functions draw the outlines of
       the specified rectangle or rectangles as if a five-point PolyLine pro-
       tocol request were specified for each 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.

STRUCTURES

       The XRectangle structure contains:
                 dow or Pixmap.

       BadGC     A value for a GContext argument does not name a defined GCon-
                 text.

       BadMatch  An InputOnly window is used as a Drawable.

       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.
