static void free_ldfile ( )

static

Free LDFILE and all resources associated with it.

References internal_ldfile::fd.

Referenced by ldclose(), and ldopen().

static void free_object ( )

static

Release the memory associated with the current object, if one has
   been mapped.

References internal_ldfile::object, internal_ldfile::object_size, and internal_ldfile::page_offset.

Referenced by ldclose(), and ldopen().

int ldclose ( )

Implement the API-defined ldclose function.

char* ldgetname ( )

Implement the API-defined ldgetname function.

References internal_syment::n_name, internal_syment::n_zeroes, internal_ldfile::object, internal_ldfile::object_size, offset, and string_within_bounds_p().

LDFILE* ldopen ( )

Implement the API-defined ldopen function.

int ldtbread ( )

Implement the API-defined ldtbread function.

static bool open_file ( )

static

LDFILE is a zero-initialized structure.  Try to open FILENAME,
   returning true on success.

References internal_ldfile::fd, read_big_archive(), and read_xcoff_object().

Referenced by ldopen().

static bool read_archive_member ( )

static

Try to read an archive member at OFFSET bytes into LDFILE.
   Return true on success, recording the member and object
   information in LDFILE.

static bool read_big_archive ( )

static

Try to treat LDFILE as a non-empty big archive.  Return true
   on success, storing the member and object information for
   the first member in LDFILE.

Read SIZE bytes starting at DATA as a big-endian value.

static bool read_xcoff_object	(	LDFILE *	ldfile,
		size_t	offset,
		size_t	object_size,
		off_t	next_member
	)

static

Try to read the file header for an XCOFF object at OFFSET bytes into
   LDFILE.  The object is expected to be OBJECT_SIZE bytes in size.
   If the object is a member of an archive, NEXT_MEMBER is the offset
   of the next member, otherwise it is -1.

   Return true on success, recording the object information in LDFILE.

static bool string_within_bounds_p ( )

static

Return true if STRING is less than SIZE bytes long.  EXTRA_TERMINATOR
   is another character (besides '\0') that acts as a terminator,
   or '\0' if none.

Referenced by ldgetname().

static bool within_object_p ( )

inlinestatic

Check that LDFILE's current object has SIZE bytes starting at OFFSET.
