GELF_GETMOVE(3) BSD Library Functions Manual GELF_GETMOVE(3)NAME
gelf_getmove, gelf_update_move — read and update Elf Move information
LIBRARY
library “libelf”
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-depen‐
dent 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 informa‐
tion 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 num‐
ber 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.
