FUNCTION

SYNOPSIS
bfd_boolean bfd_add_gnu_debuglink (bfd * abfd, const char * filename);
struct sec * bfd_create_gnu_debuglink_section (bfd * abfd, const char * filename);
DESCRIPTION
Takes a @var{BFD} and adds a .gnu_debuglink section containing a link
to the specified @var{filename}. The filename should be relative to
the current directory.
Takes a @var{BFD} and adds a .gnu_debuglink section to it. The section is sized
to be big enough to contain a link to the specified @var{filename}.
RETURNS
A pointer to the new section is returned if all is ok. Otherwise <<NULL>> is
returned and bfd_error is set.
