title: nftw thread safe
body: <p>Is there any thread safe implementation of <a href="http://pubs.opengroup.org/onlinepubs/9699919799/functions/nftw.html" rel="nofollow">nftw()</a> in C/C++? In the documentation it says </p>
  
  <blockquote>
    <p>"The nftw() function need not be thread-safe."</p>
  </blockquote>
  
  <p>I'm going to use nftw for a recursive delete function to walk through the directory structure in a multi threaded application.</p>
