Hi All,

Can I use attribute *data to send a string token in agentx get pdu

typedef struct variable_list {
   /** NULL for last variable */
   struct variable_list *next_variable;
   /** Object identifier of variable */
   oid            *name;
   /** number of subid's in name */
   size_t          name_length;
   /** ASN type of variable */
   u_char          type;
   /** value of variable */
    netsnmp_vardata val;
   /** the length of the value to be copied into buf */
   size_t          val_len;
   /** buffer to hold the OID */
   oid             name_loc[MAX_OID_LEN];
   /** 90 percentile < 40. */
   u_char          buf[40];
   /** (Opaque) hook for additional data */
   void           *data;  <--------------------------------- Can I pass
string token here
   /** callback to free above */
   void            (*dataFreeHook)(void *);
   int             index;
} netsnmp_variable_list;

Thanks,
Pushpa.T
