Shall we check if passed parameters are valid?

In the SDK Examples, the SculptingTool example (sculpting.cpp) performs some checks in ToolData::MouseInput().

Bool SculptingTool::MouseInput(BaseDocument *pDoc, BaseContainer &data, BaseDraw *pDraw, EditorWindow *win, const BaseContainer &msg)  
{  
  if (!pDoc)  
      return TRUE;  
  if (pDraw != pDoc->GetActiveBaseDraw())  
      return TRUE;  
  
  /* .. */  
}

Why should Cinema pass invalid arguments to our plugins, should we really perform these kind of checks?

Better safe than sorry :) It may be a bit over defensive but you should never assume a pointer to be valid, especially in a multi-threaded application as CINEMA 4D.
