              *attributes);

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

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

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

       int XSetWindowColormap(Display *display, Window w, Colormap colormap);

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, ParentRelative, or None.

       border_pixel
                 Specifies the entry in the colormap.

       border_pixmap
                 Specifies the border pixmap or CopyFromParent.

       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.

       colormap  Specifies the colormap.

DESCRIPTION

       Depending  on  the  valuemask,  the  XChangeWindowAttributes  function  uses the window attributes in the
       XSetWindowAttributes 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 XClearWindow.
       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 window to None or ParentRelative restores the default
       background pixmap.  Changing the border of a root window to CopyFromParent 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 WhenMapped or Always, 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  ColormapNotify
       event.   Changing the colormap of a visible window may have no immediate effect on the screen because the
       map may not be installed (see XInstallColormap).  Changing the cursor of a root window to  None  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  SubstructureRedirectMask,  ResizeRedirectMask, and ButtonPressMask.  If a client attempts to
       select any of these event masks and some other  client  has  already  selected  one,  a  BadAccess  error
       results.  There is only one do-not-propagate-mask for a window, not one per client.

       XChangeWindowAttributes  can  generate BadAccess, BadColor, BadCursor, BadMatch, BadPixmap, BadValue, and
       BadWindow errors.

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

       XSetWindowBackground can generate BadMatch and BadWindow errors.

       The XSetWindowBackgroundPixmap function sets the background pixmap of the window to the specified pixmap.
       The background pixmap can immediately be freed if no further explicit references to it are  to  be  made.
       If  ParentRelative  is  specified,  the  background pixmap of the window's parent is used, or on the root
       window, the default background is restored.  If you try to change the background of an InputOnly  window,
       a BadMatch error results.  If the background is set to None, the window has no defined background.

       XSetWindowBackgroundPixmap can generate BadMatch, BadPixmap, and BadWindow errors.

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

       XSetWindowBorder can generate BadMatch and BadWindow errors.

       The XSetWindowBorderPixmap 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 CopyFromParent, a copy of the parent window's border pixmap is used.  If you attempt  to  perform
       this on an InputOnly window, a BadMatch error results.

       XSetWindowBorderPixmap can generate BadMatch, BadPixmap, and BadWindow errors.

       The  XSetWindowColormap  function sets the specified colormap of the specified window.  The colormap must
       have the same visual type as the window, or a BadMatch error results.

       XSetWindowColormap can generate BadColor, BadMatch, and BadWindow errors.

DIAGNOSTICS

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

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

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

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

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

       BadMatch  An InputOnly window locks this attribute.

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

       BadValue  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.

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