FUNCTION
bfd_openr_next_archived_file
DESCRIPTION
Provided a BFD, @var{archive}, containing an archive and NULL, open
an input BFD on the first contained element and returns that.
- Subsequent calls should pass
- the archive and the previous return value to return a created
- BFD to the next contained element. NULL is returned when there
- are no more.
+ Subsequent calls should pass the archive and the previous return
+ value to return a created BFD to the next contained element. NULL
+ is returned when there are no more.
+ Note - if you want to process the bfd returned by this call be
+ sure to call bfd_check_format() on it first.
