     int XConfigureWindow(Display *display, Window w, unsigned
          value_mask);

     int XMoveWindow(Display *display, Window w, int x, y);

     int XResizeWindow(Display *display, Window w, unsigned

ARGUMENTS

     display   Specifies the connection to the X server.

     value_mask
               Specifies which values are to be set using infor-
               mation in the values structure. This mask is the
               bitwise inclusive OR of the valid configure window
               values bits.

     values    Specifies the XWindowChanges structure.

     w         Specifies the window to be reconfigured, moved, or
               resized..

     width     Specifies the width of the window border.

     width
     height    Specify the width and height, which are the inte-
               rior dimensions of the window. of the window's
               border or the window itself if it has no border or
               define the new position of the window relative to
               its parent

     x
     y         Specify the x and y coordinates, which define the
               new location of the top-left pixel.

DESCRIPTION

     The XConfigureWindow function uses the values specified in
     the XWindowChanges structure to reconfigure a window's size,
     position, border, and stacking order. Values not specified
     are taken from the existing geometry of the window.

     If a sibling is specified without a stack_mode or if the
     window is not actually a sibling, a BadMatch error results.
     Note that the computations for BottomIf, TopIf, and Opposite
     are performed with respect to the window's final geometry
     (as controlled by the other arguments passed to XConfi-
     gureWindow), not its initial geometry. Any backing store
     contents of the window, its inferiors, and other newly visi-
     ble windows are either discarded or changed to reflect the
     current screen contents (depending on the implementation).

     XConfigureWindow can generate BadMatch, BadValue, and
     BadWindow errors.

     The XMoveWindow function moves the specified window to the
     specified x and y coordinates, but it does not change the
     window's size, raise the window, or change the mapping state
     of the window. Moving a mapped window may or may not lose
     the window's contents depending on if the window is obscured
     by nonchildren and if no backing store exists. If the con-
     tents of the window are lost, the X server generates Expose
     events. Moving a mapped window generates Expose events on
     any formerly obscured windows.

     If the override-redirect flag of the window is False and
     some other client has selected SubstructureRedirectMask on
     the parent, the X server generates a ConfigureRequest event,
     and no further processing is performed. Otherwise, the win-
     dow is moved.

     XMoveWindow can generate a BadWindow error.

     The XResizeWindow function changes the inside dimensions of
     the specified window, not including its borders. This func-
     tion does not change the window's upper-left coordinate or
     the origin and does not restack the window. Changing the
     size of a mapped window may lose its contents and generate
     Expose events. If a mapped window is made smaller, changing
     its size generates Expose events on windows that the mapped
     window formerly obscured.

     If the override-redirect flag of the window is False and
     some other client has selected SubstructureRedirectMask on
     the parent, the X server generates a ConfigureRequest event,
     and no further processing is performed. If either width or
     height is zero, a BadValue error results.

     XResizeWindow can generate BadValue and BadWindow errors.

     The XMoveResizeWindow function changes the size and location
     of the specified window without raising it. Moving and
     resizing a mapped window may generate an Expose event on the
     window. Depending on the new size and location parameters,

     moving and resizing a window may generate Expose events on
     windows that the window formerly obscured.

     If the override-redirect flag of the window is False and
     some other client has selected SubstructureRedirectMask on
     the parent, the X server generates a ConfigureRequest event,
     and no further processing is performed. Otherwise, the win-
     dow size and location are changed.

     XMoveResizeWindow can generate BadValue and BadWindow
     errors.

     The XSetWindowBorderWidth function sets the specified
     window's border width to the specified width.

     XSetWindowBorderWidth can generate a BadWindow error.

STRUCTURES

     The XWindowChanges structure contains:

     /* Configure window value mask bits */
     #define   CWX                         (1<<0)
     #define   CWY                         (1<<1)
     #define   CWWidth                     (1<<2)
     #define   CWHeight                    (1<<3)
     #define   CWBorderWidth               (1<<4)
     #define   CWSibling                   (1<<5)
     #define   CWStackMode                 (1<<6)
     /* Values */

     typedef struct {
          int x, y;
          int width, height;
          int border_width;
          Window sibling;
          int stack_mode;
     } XWindowChanges;

     The x and y members are used to set the window's x and y
     coordinates, which are relative to the parent's origin and
     indicate the position of the upper-left outer corner of the
     window. The width and height members are used to set the
     inside size of the window, not including the border, and
     must be nonzero, or a BadValue error results. Attempts to
     configure a root window have no effect.

     The border_width member is used to set the width of the
     border in pixels. Note that setting just the border width
     leaves the outer-left corner of the window in a fixed posi-
     tion but moves the absolute position of the window's origin.
     If you attempt to set the border-width attribute of an Inpu-
     tOnly window nonzero, a BadMatch error results.

     The sibling member is used to set the sibling window for
     stacking operations. The stack_mode member is used to set
     how the window is to be restacked and can be set to Above,
     Below, TopIf, BottomIf, or Opposite.

DIAGNOSTICS

     BadMatch  An InputOnly window is used as a Drawable.

     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.

     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 gen-
               erate this error.

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