As you wrote, the comment does mention that you can't use this to convert negative integers, and it WARN()'s if the user tries that anyway. > Comment > mentions this, but we don't want to such horrible and not well thought > out function to lib/ . > > If anything it should be strtonum() with additional trailing '\n' check. That's fine, I'll use strtonum() in any case. It turns out the behaviour that we want is precisely what strtonum() offers, plus that also works for negative integers, so we might as well just copy it over. Andrew, I'll diff a new patch implementing strtonum(3) _not_ based on this one, so you may safely drop this.
