Correct.

The same function is used for *all* values - OIDs, string-based values
and integers,  You should think of the 'u_char*' parameter as a void
pointer, and cast it to the appropriate type.

i.e.

   write_Name( int action,
                        u_char  *var_val, u_char  var_val_type, size_t
var_val_len,
                       u_char   *statP,  oid  *name, size_t   name_len) {

       long new_val = *(long *)var_val;
       // etc, etc
   }
