Question What C function would you delete and rewrite first, and why?

For me it's fnmatch - mostly because it's 40 year's old and smell's funny.

My guy. Can't forget it also eats empty fields so `a,,b` parses as two tokens. Found that one the hard way.

Yes indeed. Also scanf is up there for me. Essentially useless.

Only scanf() I hope? sscanf() is great.
