  79                 errno codes, and the corresponding descriptions. For example,
  80                 if given <literal>ENOENT</literal> on a Linux system, it
  81                 prints out the code 2 and the description "No such file or directory".
  82                 If given the code 2, it prints <literal>ENOENT</literal>
  83                 and the same description.</para>
