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.
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.
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.
