title: How to use delay function in C on Ubuntu
body: <p>I used delay function in Turbo C/C++ in Windows and it worked well.</p>
  
  <p>Now my problem is: I want to run the delay function in Ubuntu but it showing the following error:</p>
  
  <pre class="lang-none prettyprint-override"><code>pass.c:(.text+0x1d): undefined reference to `delay'
  collect2: error: ld returned 1 exit status
  </code></pre>
  
  <p>Now the header file in Windows was <code>dos.h</code> which is not available in Ubuntu! So is there any different header file or is there no function named <code>delay</code> supported in Ubuntu? If so then please give me any other example rather than <code>delay</code>.</p>
