  32     NOTES
  33         This function returns a pointer to a static buffer
  34         containing (the first PASS_MAX bytes of) the password without the
  35         trailing newline, terminated by a null byte ('\0').
  36
  37         Function is not re-entrant. Results will be overwritten by
  38         subsequent calls.
