Look for an address in a section. This is called via bfd_map_over_sections.

static void find_offset_in_section ( bfd *  abfd, asection *  section, sym_info *  psi  )

static

Look for an offset in a section. This is directly called.

off_t get_file_size

(

const char *

file_name

)

Returns the size of the named file. If the file does not exist, or if it is not a real file, then a suitable non-fatal error message is printed and zero is returned.

void set_default_bfd_target

(

void

Set the default BFD target based on the configured target. Doing this permits the binutils to be configured for a particular target, and linked against a shared BFD library which was configured for a different target.
