SYNOPSIS
#include <gelf.h> GElf_Move *
gelf_getmove (Elf_Data *data int ndx GElf_Move *move); int
gelf_update_move (Elf_Data *data int ndx GElf_Move *move);
DESCRIPTION
These convenience functions are used to retrieve and update class-dependent
Vt Elf32_Move
and
Vt Elf64_Move
structures in an ELF object.
Argument
data
is an
Vt Elf_Data
descriptor associated with a section of type
SHT_SUNW_move
Argument
ndx
is the index of the move record being retrieved or updated.
The class-independent
Vt GElf_Move
structure is described in
gelf(3).
Function
gelf_getmove ();
retrieves class-dependent move record at index
ndx
in data buffer
data
and copies it to the destination pointed to by argument
move
after translation to class-independent form.
Function
gelf_update_move ();
converts the class-independent move information pointed to
by argument
move
to class-dependent form, and writes it to the move record at index
ndx
in the data buffer described by argument
data
Function
gelf_update_move ();
signals an error if any of the values in the class-independent
representation exceeds the representable limits of the target
type.
RETURN VALUES
Function
gelf_getmove ();
returns the value of argument
move
if successful, or NULL in case of an error.
Function
gelf_update_move ();
returns a non-zero value if successful, or zero in case of an error.
ERRORS
These functions may fail with the following errors:
Bq Er ELF_E_ARGUMENT
Arguments
data
or
move
were NULL.
Bq Er ELF_E_ARGUMENT
Argument
ndx
was less than zero or larger than the number of records in the data
descriptor.
Bq Er ELF_E_ARGUMENT
Data descriptor
data
was not associated with a section containing move information.
