	      *background_color);

       int XFreeCursor(Display *display, Cursor cursor);

       Status XQueryBestCursor(Display *display, Drawable d, unsigned int width, unsigned int
	      height, unsigned int *width_return, unsigned int *height_return);

ARGUMENTS
       background_color

       cursor	 Specifies the cursor.

       d	 Specifies the drawable, which indicates the screen.

       display	 Specifies the connection to the X server.

		 for.

       width_return
       height_return

DESCRIPTION
       The XRecolorCursor function changes the color of the specified cursor, and if the cursor
       is being displayed on a screen, the change is visible immediately.  The pixel members of
       the XColor structures are ignored; only the RGB values are used.

       XRecolorCursor can generate a BadCursor error.

       The XFreeCursor function deletes the association between the cursor resource ID and the
       specified cursor.  The cursor storage is freed when no other resource references it.  The
       specified cursor ID should not be referred to again.

       XFreeCursor can generate a BadCursor error.

       Some displays allow larger cursors than other displays.	The XQueryBestCursor function
       provides a way to find out what size cursors are actually possible on the display.  It
       returns the largest size that can be displayed.	Applications should be prepared to use
       smaller cursors on displays that cannot support large ones.

       XQueryBestCursor can generate a BadDrawable error.

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

       BadDrawable
		 A value for a Drawable argument does not name a defined Window or Pixmap.
