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.
gelf_getsym() returns the value of argument
sym if successful, or NULL in
case of an error. Function gelf_update_sym() returns a
non-zero value if successful, or zero in case of an error.
