	     Display *display;

	     unsigned int width, height;
	     Bool exposures;

	     Display *display;
	     Window w;

ARGUMENTS
       display	 Specifies the connection to the X server.

DESCRIPTION
       The function paints a rectangular area in the specified window accord‐
       ing to the specified dimensions with the window's background pixel or
       pixmap.	The subwindow-mode effectively is If width is zero, it is
       replaced with the current width of the window minus x.  If height is
       zero, it is replaced with the current height of the window minus y.  If
       the window has a defined background tile, the rectangle clipped by any
       children is filled with this tile.  If the window has background the
       contents of the window are not changed.	In either case, if exposures
       is one or more events are generated for regions of the rectangle that
       are either visible or are being retained in a backing store.  If you
       specify a window whose class is a error results.

       can generate and errors.

       equivalent to (display, w, 0, 0, 0, 0, If the window has a defined
       background tile, the rectangle is tiled with a plane-mask of all ones
       and function.  If the window has background the contents of the window
       are not changed.	 If you specify a window whose class is a error
       results.

       can generate and errors.

DIAGNOSTICS
       An	 window is used as a Drawable.

       Some numeric value falls outside the range of values accepted by the
       request.
		 Unless a specific 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.

       A value for a Window argument does not name a defined Window.
