        <<bfd_close>>.  @var{close} either succeeds returning 0, or
        fails returning -1 (setting <<bfd_error>>).
 
+       Calls @var{stat} to fill in a stat structure for bfd_stat,
+       bfd_get_size, and bfd_get_mtime calls.  @var{stat} returns 0
+       on success, or returns -1 on failure (setting <<bfd_error>>).

        If <<bfd_openr_iovec>> returns <<NULL>> then an error has
        occurred.  Possible errors are <<bfd_error_no_memory>>,
        <<bfd_error_invalid_target>> and <<bfd_error_system_call>>.
