Name
       XChangeWindowAttributes, XSetWindowBackground, XSetWindowBackgroundPixmap, XSetWindowBorder, XSetWindowBorderPixmap - change window
       attributes

Syntax
       XChangeWindowAttributes(display, w, valuemask, attributes)
	  Display *display;
	  Window w;
	  unsigned long valuemask;
	  XSetWindowAttributes *attributes;

       XSetWindowBackground(display, w, background_pixel)
	  Display *display;
	  Window w;
	  unsigned long background_pixel;

       XSetWindowBackgroundPixmap(display, w, background_pixmap)
	  Display *display;
	  Window w;
	  Pixmap background_pixmap;

       XSetWindowBorder(display, w, border_pixel)
	  Display *display;
	  Window w;
	  unsigned long border_pixel;

       XSetWindowBorderPixmap(display, w, border_pixmap)
	  Display *display;
	  Window w;
	  Pixmap border_pixmap;

Arguments
       attributes
		 Specifies the structure from which the values (as specified by the value mask) are to be taken.  The value mask should have the
		 appropriate bits set to indicate which attributes have been set in the structure.

       background_pixel
		 Specifies the pixel that is to be used for the background.

       background_pixmap
		 Specifies the background pixmap, or

       border_pixel
		 Specifies the entry in the colormap.

       border_pixmap
		 Specifies the border pixmap or

       display	 Specifies the connection to the X server.

       valuemask Specifies which window attributes are defined in the attributes argument.  This mask is the bitwise inclusive OR of the valid
		 attribute mask bits.  If valuemask is zero, the attributes are ignored and are not referenced.

       w	 Specifies the window.

Description
       Depending on the valuemask, the function uses the window attributes in the structure to change the specified window attributes.	Changing
       the background does not cause the window contents to be changed.  To repaint the window and its background, use Setting the border or
       changing the background such that the border tile origin changes causes the border to be repainted.  Changing the background of a root win-
       dow to or restores the default background pixmap.  Changing the border of a root window to restores the default border pixmap.  Changing
       the win-gravity does not affect the current position of the window.  Changing the backing-store of an obscured window to or or changing the
       backing-planes, backing-pixel, or save-under of a mapped window may have no immediate effect.  Changing the colormap of a window (that is,
       defining a new map, not changing the contents of the existing map) generates a event.  Changing the colormap of a visible window may have
       no immediate effect on the screen because the map may not be installed (see Changing the cursor of a root window to restores the default
       cursor.	Whenever possible, you are encouraged to share colormaps.

       Multiple clients can select input on the same window.  Their event masks are maintained separately.  When an event is generated, it is
       reported to all interested clients.  However, only one client at a time can select for and If a client attempts to select any of these
       event masks and some other client has already selected one, a error results.  There is only one do-not-propagate-mask for a window, not one
       per client.

       can generate and errors.

       The function sets the background of the window to the specified pixel value.  Changing the background does not cause the window contents to
       be changed.  uses a pixmap of undefined size filled with the pixel value you passed.  If you try to change the background of an window, a
       error results.

       can generate and errors.

       The function sets the background pixmap of the window to the specified pixmap.  The background pixmap can immediately be freed if no fur-
       ther explicit references to it are to be made.  If is specified, the background pixmap of the window's parent is used, or on the root win-
       dow, the default background is restored.  If you try to change the background of an window, a error results.  If the background is set to
       the window has no defined background.

       can generate and errors.

       The function sets the border of the window to the pixel value you specify.  If you attempt to perform this on an window, a error results.

       can generate and errors.

       The function sets the border pixmap of the window to the pixmap you specify.  The border pixmap can be freed immediately if no further
       explicit references to it are to be made.  If you specify a copy of the parent window's border pixmap is used.  If you attempt to perform
       this on an window, a error results.

       can generate and errors.

Diagnostics
       A client attempted
		 to free a color map entry that it did not already allocate.

       A client attempted
		 to store into a read-only color map entry.

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

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

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

       An	 window locks this attribute.

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

       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.
