Yeah, I was thinking the former.

Now, I want it on the record that this possibility *did* occur to me
before I wrote Greg :-) ... So I went and looked it up. The combined
manual entry for strcmp() and strncmp() on my system says:

   The strcmp() function compares the two strings s1 and s2.
   It returns an integer less than, equal to, or greater than
   zero if s1 is found, respectively, to be less than, to
   match, or be greater than s2.
   
   The strncmp() function is similar, except it only compares
   the first n characters of s1.

Which is at best ambiguous. I just went and looked it up in K&R.
They get it right, by inserting an "at most" before "the first".

Thanks for the reminder, Joe!
