     int XRecolorCursor(Display *display, Cursor cursor, XColor
          *foreground_color, XColor *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
               Specifies the RGB values for the background of the
               source.

     cursor    Specifies the cursor.

               screen.

     display   Specifies the connection to the X server.

     foreground_color

               source.

     width
     height    Specify the width and heightof the cursor that you
               want the size information for.

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

DESCRIPTION
     The XRecolorCursor function changes the color of the speci-
     fied 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.  Applica-
     tions 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.
