XClearWindow()															    XClearWindow()

Name
  XClearWindow - clear an entire window.

Synopsis
  XClearWindow(display, w)
	Display *display;
	Window w;

Arguments
  display   Specifies a connection to an X server; returned from XOpenDisplay().

  w	    Specifies the ID of the window to be cleared.

Description
  XClearWindow()  clears  a  window,  but  does not cause exposure events.  This function is equivalent to XClearArea(display, w, 0, 0, 0, 0,
  False).

  If the window has a defined background tile or it is ParentRelative, the rectangle is tiled with a plane_mask of all 1's  and  function  of
  GXcopy.  If the window has background None, the contents of the window are not changed.

  For more information, see Volume One, Chapter 6, Drawing Graphics and Text.

Errors
  BadMatch  If w is an InputOnly class window.

  BadWindow

NAME

       XClearArea, XClearWindow - clear area or window

SYNTAX

       XClearArea(display, w, x, y, width, height, exposures)
	     Display *display;
	     Window w;
	     int x, y;
	     unsigned int width, height;
	     Bool exposures;

       XClearWindow(display, w)
	     Display *display;
	     Window w;

ARGUMENTS

       display	 Specifies the connection to the X server.

       exposures Specifies a Boolean value that indicates if Expose events are to be generated.

       w	 Specifies the window.

       width
       height	 Specify the width and height, which are the dimensions of the rectangle.  and specify the upper-left corner of the rectangle

       x
       y	 Specify the x and y coordinates, which are relative to the origin of the window.

DESCRIPTION

       The XClearArea function paints a rectangular area in the specified window according to the specified dimensions with the window's back-
       ground pixel or pixmap.	The subwindow-mode effectively is ClipByChildren.  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 None, the contents of the window are
       not changed.  In either case, if exposures is True, one or more Expose 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 InputOnly, a BadMatch error results.

       XClearArea can generate BadMatch, BadValue, and BadWindow errors.

       The XClearWindow function clears the entire area in the specified window and is equivalent to XClearArea (display, w, 0, 0, 0, 0, False).
       If the window has a defined background tile, the rectangle is tiled with a plane-mask of all ones and GXcopy function.  If the window has
       background None, the contents of the window are not changed.  If you specify a window whose class is InputOnly, a BadMatch error results.

       XClearWindow can generate BadMatch and BadWindow errors.

DIAGNOSTICS

       BadMatch  An InputOnly window is used as a Drawable.

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

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