LIBRARY

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 Elf32_Move and Elf64_Move structures in an ELF object.Argument data is an
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 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:
- [
ELF_E_ARGUMENT] - Arguments data or move were NULL.
- [
ELF_E_ARGUMENT] - Argument ndx was less than zero or larger than the number of records in the data descriptor.
- [
ELF_E_ARGUMENT] - Data descriptor data was not associated with a section containing move information.
- [
ELF_E_RANGE] - A value was not representable in the target type.
