Hi Masami, This was somewhat my idea. Why do you think it's over engineering? This is your code, so you have final say. I'm not going to push it. I'm just curious to your thoughts. It is interesting that snprintf() takes a size_t size, and the iterator inside is also size_t, but then it returns the value as an int. That itself just looks wrong (and has nothing to do with your code). -- Steve
