These convenience functions are used to retrieve and update class-dependent
Elf32_Rel
or
Elf64_Rel
structures in an ELF object.
Argument
data
is an
Elf_Data
descriptor associated with a section of type
SHT_REL.
Argument
ndx
is the index of the entry being retrieved or updated.
The class-independent
GElf_Rel
structure is described in
gelf(3).
Function
gelf_getrel()
retrieves the class-dependent entry at index
ndx
in data buffer
data
and copies it to the destination pointed to by argument
rel
after translation to class-independent form.
Function
gelf_update_rel()
converts the class-independent entry pointed to
by argument
rel
to class-dependent form, and writes it to the entry at index
ndx
in the data buffer described by argument
data.
Function
gelf_update_rel()
signals an error if any of the values in the class-independent
representation exceeds the representable limits of the target
type.
