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.
