title: I cannot use termios.h in cygwin64
body: <p>I am making an application where I think I will need to use <code>termios.h</code> But I have windows 10. I installed cygwin64. I type in <code>gcc test.c -o test.exe</code> in the terminal. I still get <code>fatal error: termios.h: No such file or directory #include &lt;termios.h&gt;</code> Is there something I had to do during installation?</p>
  <p>The code is just prints hello world but I included <code>termios.h</code></p>
  <pre class="lang-c prettyprint-override"><code>#include &lt;stdio.h&gt;
  #include &lt;termios.h&gt;
  
  int main(){
       printf(&quot;Hello World!&quot;);
  
       return 0;
  }
  </code></pre>
