Argument data is an
Elf_Data descriptor associated with a section of type
SHT_DYNAMIC
. Argument ndx is
the index of the entry being retrieved or updated. The class-independent
GElf_Dyn structure is described in
gelf(3).
Function gelf_getdyn
() retrieves the
class-dependent entry at index ndx in data buffer
data and copies it to the destination pointed to by
argument dyn after translation to class-independent
form.
Function gelf_update_dyn
() converts the
class-independent entry pointed to by argument dyn to
class-dependent form, and writes it to the entry at index
ndx in the data buffer described by argument
data. Function
gelf_update_dyn
() signals an error if any of the
values in the class-independent representation exceeds the representable
limits of the target type.
gelf_getdyn
() returns the value of argument
dyn if successful, or NULL
in
case of an error. Function gelf_update_dyn
() returns a
non-zero value if successful, or zero in case of an error.
