Can you elaborate please? Your description does not match what I see. My understanding is that this is a way to more strongly type function arguments, as an alternative to va_arg.

Yes, but the final result is out_str, not a forward to console, isn't it?

Either way, the format string discussion for the printf familiy of functions is very similar between them

[anonymousiam]

Okay, got it. So you are agreeing with me that the author should have used printf instead of sprintf.

Thanks!
