Your suggestion makes no sense. If you don't want to use a format string, use a function that takes a regular string, like puts, instead of a vprintf variant.

Your suggestion makes no sense. If you don't want to use a format string, use a function that takes a regular string, like puts, instead of a vprintf variant. Why would anyone go to the trouble of escaping a format string so they can use it with a function whose sole purpose is to parse format strings? (Which you can already do, by the way, by using vprintf correctly.)
