XReparentWindow(display, w, parent, x, y)
      Display *display;
      Window w;
      Window parent;
      int x, y;
| display | Specifies the connection to the X server. | 
| w | Specifies the window. | 
| parent | Specifies the parent window. | 
|  x y  | Specify the x and y coordinates of the position in the new parent window. | 
After reparenting the specified window, XReparentWindow() causes the X server to generate a ReparentNotify event. The override_redirect member returned in this event is set to the window's corresponding attribute. Window manager clients usually should ignore this window if this member is set to True . Finally, if the specified window was originally mapped, the X server automatically performs a MapWindow request on it.
The X server performs normal exposure processing on formerly obscured windows. The X server might not generate Expose events for regions from the initial UnmapWindow request that are immediately obscured by the final MapWindow request. A BadMatch error results if:
XReparentWindow() can generate BadMatch and BadWindow errors.
| 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. | 
| BadWindow | A value for a Window argument does not name a defined Window. |
