-FUNCTION
- bfd_simple_relocate_secton
-
-SYNOPSIS
- bfd_byte *bfd_simple_get_relocated_section_contents
- (bfd *abfd, asection *sec, bfd_byte *outbuf, asymbol **symbol_table);
-
-DESCRIPTION
- Returns the relocated contents of section @var{sec}. The symbols in
- @var{symbol_table} will be used, or the symbols from @var{abfd} if
- @var{symbol_table} is NULL. The output offsets for debug sections will
- be temporarily reset to 0. The result will be stored at @var{outbuf}
- or allocated with @code{bfd_malloc} if @var{outbuf} is @code{NULL}.
-
- Returns @code{NULL} on a fatal error; ignores errors applying
- particular relocations.
