These convenience functions are used to retrieve and update class-dependent
Elf32_Rela or
Elf64_Rela structures in an ELF object.
Argument
data is an
Elf_Data descriptor associated with a section of type
SHT_RELA. Argument
ndx is the index of the entry being retrieved or updated. The class-independent
GElf_Rela structure is described in
gelf(3).
Function
gelf_getrela() retrieves the class-dependent entry at index
ndx in data buffer
data and copies it to the destination pointed to by argument
rela after translation to class-independent form.
Function
gelf_update_rela() converts the class-independent entry pointed to by argument
rela to class-dependent form, and writes it to the entry at index
ndx in the data buffer described by argument
data. Function
gelf_update_rela() signals an error if any of the values in the class-independent representation exceeds the representable limits of the target type.
