                                                                                       explain_opendir_or_die(3)

       The  explain_opendir_or_die  function  is  used  to  call  the  opendir(3)  system  call.   On failure an
       explanation will be printed to stderr, obtained from explain_opendir(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:
              DIR *dir = explain_opendir_or_die(pathname);

       pathname
               The pathname, exactly as to be passed to the opendir(3) system call.

       Returns:
               On success, a pointer to the directory stream.  On failure, prints an explanation and exits, does
               not return.
