title: Why is strtok() Considered Unsafe?
body: <p>What feature(s) of <code>strtok</code> is unsafe (in terms of buffer overflow) that I need to watch out for?</p>
  
  <p>What's a little weird to me is that <code>strtok_s</code> (which is "safe") in Visual C++ has an extra "context" parameter, but it looks like it's the same in other ways... is it the same, or is it actually different?</p>
