NAME

gelf_getmove, gelf_update_move —

read and update Elf Move information

LIBRARY

ELF Access Library (libelf, -lelf)

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.
[ELF_E_VERSION]: The Elf_Data descriptor denoted by argument data is associated with an ELF object with an unsupported version.
