XSetWindowBorder()														XSetWindowBorder()

Name
  XSetWindowBorder - change a window border pixel value attribute and repaint the border.

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

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

  w	   Specifies the window ID.  Must be an InputOutput window.

  border_pixel
	   Specifies the colormap entry with which the server will paint the border.

Description
  XSetWindowBorder() sets the border_pixel attribute of window w to a pixel value, and repaints the border.  The border is also automatically
  repainted after Expose events.

  Use XSetWindowBorderPixmap() to create a tiled border.  On top-level windows, the window manager often resets the border,  so  applications
  should not depend on their settings.

  For more information, see Volume One, Chapter 4, Window Attributes.
