Yes, I’m aware of it. I’m just tired by these layman’s “oh that’s another reason to ditch C strings”, when it has nothing to do with it. Working with offsets requires handling offsets and lengths, be it explicit ‘off’ and ‘n’ or a string_view. All that is needed in this case in C is snscanf (note the ‘n’), so that it would know its limits apriori, like snprintf does. Sadly that ‘n’ never made it into the standard.
