             size information for.

   width_return
   height_return
             Return the best width and height that is closest to the

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.
