                                                                                       explain_readdir_or_die(3)

       The  explain_readdir_or_die  function  is  used  to  call  the  readdir(2)  system  call.   On failure an
       explanation will be printed to stderr, obtained from explain_readdir(3), and then the process  terminates
       by calling exit(EXIT_FAILURE).

       This function is intended to be used in a fashion similar to the following example:
              explain_readdir_or_die(dir);

       dir     The dir, exactly as to be passed to the readdir(2) system call.

       Returns:
               a  pointer  to  a  dirent  structure,  or  NULL if end‐of‐file is reached.  On failure, prints an
               explanation and exits.
