Coroutine vs Fiber difference clarification : <p>In the book <code>Linux System Programming, 2nd Edition</code>, the difference between coroutines and fiber is explained as follows:</p>

<blockquote>
  <p>Coroutines and fibers provide a unit of execution even lighter in weight than the thread (with the former being their name when they are a programming language construct, and the latter when they are a system construct).</p>
</blockquote>

<p>I have some example of Coroutines (language constructs) but unable to find the example of Fibers.</p>

<p>Can anyone provide me some example of Fiber (a system construct)?</p>
