title: how to execute a command as root
body: <p>I develop a C code on Linux (Debian). Time to time, I need to execute some commands through <code>system()</code></p>
  
  <p>I wonder if it is possible to execute a command via <code>system()</code>as root. If it is not the case, is there any function to execute a command (or run a binary) as root that I can use on the C code?</p>
