title: Get the child PID after system()
body: <p>As far as I understand, the <code>system()</code> call uses internally <code>fork()</code> and <code>exec()</code> but encapsulates them for a easier handling. </p>
  
  <p>Is it possible to get the PID from the child process created with the <code>system()</code> call?</p>
  
  <p>Aim: I want to be able to SIGINT any child process after a certain timeout. I could rebuild the <code>system()</code> function by using <code>fork()</code> and <code>exec()</code>. But all I need is the child's PID and perhaps there is shortcut by using <code>system()</code>?</p>
