       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.

       points	Specifies an array of points.

       rectangles

		 Convex, or Nonconvex.

       width
       height	Specify the width and height, which are the
		 dimensions of the rectangle to be filled or the
		 major and minor axes of the arc.

       x
       y	 Specify the x and y coordinates, which are rela-
		 tive to the origin of the drawable and specify
		 the upper-left corner of the rectangle.

DESCRIPTION
       The XFillRectangle and XFillRectangles functions fill the
       specified rectangle or rectangles as if a four-point
       FillPolygon protocol request were specified for each rect-
       angle:

       [x,y] [x+width,y] [x+width,y+height] [x,y+height]

       Each function uses the x and y coordinates, width and
       height dimensions, and GC you specify.

       XFillRectangles fills the rectangles in the order listed
       in the array.  For any given rectangle, XFillRectangle and
       XFillRectangles do not draw a pixel more than once.  If
       rectangles intersect, the intersecting pixels are drawn
       multiple times.

       Both functions use these GC components: function, plane-
       mask, fill-style, subwindow-mode, clip-x-origin, clip-y-

       origin, and clip-mask.  They also use these GC mode-depen-
       dent components: foreground, background, tile, stipple,
       tile-stipple-x-origin, and tile-stipple-y-origin.

       XFillRectangle and XFillRectangles can generate
       BadDrawable, BadGC, and BadMatch errors.

       XFillPolygon fills the region closed by the specified
       path.  The path is closed automatically if the last point
       in the list does not coincide with the first point.
       XFillPolygon does not draw a pixel of the region more than
       once.  CoordModeOrigin treats all coordinates as relative
       to the origin, and CoordModePrevious treats all coordi-
       nates after the first as relative to the previous point.

       Depending on the specified shape, the following occurs:

       o    If shape is Complex, the path may self-intersect.
	    Note that contiguous coincident points in the path
	    are not treated as self-intersection.

       o    If shape is Convex, for every pair of points inside
	    the polygon, the line segment connecting them does
	    not intersect the path.  If known by the client,
	    specifying Convex can improve performance.	If you
	    specify Convex for a path that is not convex, the
	    graphics results are undefined.

       o    If shape is Nonconvex, the path does not self-inter-
	    sect, but the shape is not wholly convex.  If known
	    by the client, specifying Nonconvex instead of Com-
	    plex may improve performance.  If you specify Noncon-
	    vex for a self-intersecting path, the graphics
	    results are undefined.

       The fill-rule of the GC controls the filling behavior of
       self-intersecting polygons.

       This function uses these GC components: function, plane-
       mask, fill-style, fill-rule, subwindow-mode, clip-x-ori-
       gin, clip-y-origin, and clip-mask.  It also uses these GC
       mode-dependent components: foreground, background, tile,
       stipple, tile-stipple-x-origin, and tile-stipple-y-origin.

       XFillPolygon can generate BadDrawable, BadGC, BadMatch,
       and BadValue errors.

       For each arc, XFillArc or XFillArcs fills the region
       closed by the infinitely thin path described by the speci-
       fied arc and, depending on the arc-mode specified in the
       GC, one or two line segments.  For ArcChord, the single
       line segment joining the endpoints of the arc is used.
       For ArcPieSlice, the two line segments joining the end-
       points of the arc with the center point are used.

XFillRectangle(3X11)	XLIB FUNCTIONS	   XFillRectangle(3X11)

       XFillArcs fills the arcs in the order listed in the array.
       For any given arc, XFillArc and XFillArcs do not draw a
       pixel more than once.  If regions intersect, the inter-
       secting pixels are drawn multiple times.

       Both functions use these GC components: function, plane-
       mask, fill-style, arc-mode, 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, and tile-stipple-y-origin.

       XFillArc and XFillArcs can generate BadDrawable, BadGC,
       and BadMatch errors.

DIAGNOSTICS
       BadDrawable
		 A value for a Drawable argument does not name a
		 defined Window or Pixmap.

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

       BadMatch An InputOnly window is used as a Drawable.

       BadMatch Some argument or pair of arguments has the cor-
		 rect type and range but fails to match in some
		 other way required by the request.

       BadValue Some numeric value falls outside the range of
		 values accepted by the request.  Unless a spe-
		 cific range is specified for an argument, the
		 full range defined by the argument's type is
		 accepted.  Any argument defined as a set of
		 alternatives can generate this error.
