'name' is a pointer to the OID array.
This is the only one that you need to be concerned about.

'name_loc' is an internal buffer, used for storing "short" OIDs
(which is the bulk of them in normal usage).   This saves the
overhead of dynamically allocating separate memory every
time a varbind OID is set up.
   This is handled automatically by the snmp_set_var_objid()
routine.

'name'

You shouldn't look at the 'name_loc' field at all.
