VXIscResult RegisterEventListener

(struct VXIscInterface* pThis,
  VXIscEventListener* eventListener,
  const VXIptr userData)

Register an event listener/user data pair for event notification
Zero or more event listeners may be registered by calling this method, each with their own user data. The combination of the event listener function and user data pointer must be unique: if the same pair is registered twice, an error is returned.

Parameters:
eventListener - [IN] Event listener function that will be called when events occur
userData - [IN] Opaque user defined data, passed to the listener for each listener invocation to permit the listener to access information it needs to react to the event.
Returns:
VXIsc_RESULT_SUCCESS on success
