These convenience functions are used to retrieve and update class-dependent
Elf32_Sym and
Elf64_Sym structures in an ELF object.
Argument
data is an
Elf_Data descriptor associated with a section of type
SHT_SYMTAB,
SHT_DYNSYM or
SHT_GNU_versym. Argument
ndx is the index of the symbol being retrieved or updated. The class-independent
GElf_Sym structure is described in
gelf(3).
Function
gelf_getsym() retrieves class-dependent symbol information at index
ndx in data buffer
data and copies it to the destination pointed to by argument
sym after translation to class-independent form.
Function
gelf_update_sym() converts the class-independent symbol information pointed to by argument
sym to class-dependent form, and writes it to the symbol entry at index
ndx in the data buffer described by argument
data. Function
gelf_update_sym() signals an error if any of the values in the class-independent representation exceeds the representable limits of the target type.
