It's even more confusing than that.  strncpy() will touch n bytes.  If  
a nul is encountered in the source string before reaching n, then from  
there to n will be filled with zeroes.  If it reaches n before  
reaching the end of the source string, it simply stops, without  
terminating.  Hence the creation of strlcpy().
