                                 int count, char *message, char *color)

           void  EZ_RemoveLedAction(EZ_Widget *led, int id)

    ARGUMENTS
           led  Specifies a LED widget.

           type  Specifies a symbolic LED action name. Must be one of
           EZ_LED_SCROLL_LEFT, EZ_LED_SCROLL_RIGHT, EZ_LED_SCROLL_UP,
           EZ_LED_SCROLL_DOWN,                  EZ_LED_SCROLL_CENTER,
           EZ_LED_SCROLL_CENTER_V,                 EZ_LED_SWEEP_LEFT,
           EZ_LED_SWEEP_RIGHT,  EZ_LED_SWEEP_UP,   EZ_LED_SWEEP_DOWN,

           EZ_LED_BOUNCE_V,     EZ_LED_SHOW,     EZ_LED_BLINK     and
           EZ_LED_SLEEP.

           delay  Specifies the time delay (in micro seconds) between
           two consecutive frames for this action. It is used to con-
           trol the speed of scrolling.

           count  Specifies  the number of times this action is going
           to be completed.

           message Specifies the message to be  displayed.  If  NULL,
           the most recent message will be displayed.

           fied action.

           id Specifies the identifier of a queued led action.

    DESCRIPTION
           EZ_QueueLedAction queues an action for an LED widget.  The
           action  will  be  executed  at  a  later time. If multiple
           actions are queued to an LED widget, they will be executed
           sequentially (FIFO).

           On  success, this function returns a unique positive inte-
           ger that identifies the action. It returns -1 on  failure.

           EZ_RemoveLedAction removes an queued action for the speci-
           fied LED widget.
