I'm not sure how portable it is, though. This is what K&R has to say
on the matter: "characters from the string are printed until a ´\0´ is
reached or until the number of characters indicated by the precision
have been printed". To me it's not clear if that means that either
cases can terminate the printing when the precision has been
specified.
