  \brief vos_event_init() - initializes a vOSS event

  The vos_event_init() function initializes the specified event. Upon
  successful initialization, the state of the event becomes initialized
  and not signaled.

  An event must be initialized before it may be used in any other event
  functions.

  Attempting to initialize an already initialized event results in
  a failure.

  \param lock - pointer to the opaque event object to initialize

  \return VOS_STATUS_SUCCESS - event was successfully initialized and
          is ready to be used.

          VOS_STATUS_E_BUSY - The implementation has detected an attempt
          to reinitialize the object referenced by event, a previously
          initialized, but not yet destroyed, event.

          VOS_STATUS_E_FAULT  - event is an invalid pointer.

          VOS_STATUS_E_FAILURE - event could not be created due to
          unknown reasons

       ***VOS_STATUS_E_RESOURCES - System resources (other than memory)
          are unavailable to initilize the event

  \brief vos_timer_stop() - Stop a vOSS Timer

  The \a vos_timer_stop() function stops a timer that has been started but
  has not expired, essentially cancelling the 'start' request.
   
  After a timer is stopped, it goes back to the state it was in after it
  was created and can be started again via a call to vos_timer_start().
  
  \param timer - the timer object to be stopped
    
  \return VOS_STATUS_SUCCESS - timer was successfully stopped.
  
          VOS_STATUS_E_INVAL - The value specified by timer is invalid.
          
          VOS_STATUS_E_FAULT  - timer is an invalid pointer.
