SYNOPSIS
- char *bfd_get_alt_debug_link_info (bfd *abfd, unsigned long *crc32_out);
+ char *bfd_get_alt_debug_link_info (bfd * abfd,
+ bfd_size_type *buildid_len,
+ bfd_byte **buildid_out);
DESCRIPTION
Fetch the filename and BuildID value for any alternate debuginfo
associated with @var{abfd}. Return NULL if no such info found,
- otherwise return filename and update @var{buildid_out}. The
- returned filename is allocated with @code{malloc}; freeing it
- is the responsibility of the caller.
+ otherwise return filename and update @var{buildid_len} and
+ @var{buildid_out}. The returned filename and build_id are
+ allocated with @code{malloc}; freeing them is the
+ responsibility of the caller.
