ARGUMENTS
display Specifies the connection to the X server.
exposures Specifies a Boolean value that indicates if events are to be
generated.
w Specifies the window.
width
height Specify the width and height, which are the dimensions of the

DESCRIPTION
The function paints a rectangular area in the specified window accordâ
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.
The function clears the entire area in the specified window and is
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

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.
