title: System limits for child processes in linux
body: <p>I am currently reading Michael Kerrisk "The Linux programming interface". In chapter dedicated to system limits it is written:</p>
  
  <blockquote>
    <p>SUSv3 requires that the value returned by <strong>sysconf</strong>() for a particular
        limit be constant for the lifetime of the calling process.</p>
  </blockquote>
  
  <p>Does that mean that if I get current system limits and use them somehow in the current process, It is a rule of good taste to get them again in a child process after <strong>fork</strong>?</p>
