SNMPTable - Multilple Instances

Hi All,

I trying to do multiple instances using Table code generated from mib2c
tool.I m able to walk,bulkget,etc., but the problem is the agent is not
recognising the end of the instance.For  example if i have created 2
instances using createEntry funtion,when i request for the third instance as
XXX.3,i shoould get Msg like "No such Instance available"

But i m error like
netsnmp_assert pss->s_snmp_errno != (-11) failed snmp_api.c:3124
snmp_build()
send response: Error building ASN.1 representation (build int size 0: s/b 4)
XXX.2

I m attaching what i ve done to generated code:

void
initialize_table_voltTable(void)
{

struct voltTable_entry *data=NULL;

........../* same as generated*/
..........

data = GetVoltData();
     if(data==NULL)
         return NULL;
}
struct voltTable_entry *GetVoltData()
{

    struct voltTable_entry
*entry=NULL,*tmp=NULL,*tmp_ptr=NULL,*tmp3=NULL,*tmp4=NULL;

    tmp = SNMP_MALLOC_TYPEDEF(struct voltTable_entry);
    if (!tmp)
        return NULL;

    tmp_ptr = SNMP_MALLOC_TYPEDEF(struct voltTable_entry);
    if (!tmp_ptr)
        return NULL;

/

    tmp = voltTable_createEntry(0);


        tmp->valid =1;

        strncpy(tmp->voltDescr,"Voltage",strlen("Voltage")+1);
        tmp->voltReading = 18;//voltReading;
        tmp->voltNominalReading =17;// voltNominalReading;
        tmp->voltNonRecovLimitHigh =16 ;//voltNonRecovLimitHigh;

//     tmp->next=NULL;

        tmp_ptr = tmp->next;

        tmp_ptr = voltTable_createEntry(1);
        tmp_ptr->valid =1;


strncpy(tmp_ptr->voltDescr,"Voltage2",strlen("Voltage22222222222")+1);
        tmp_ptr->voltReading = 10;//voltReading;
        tmp_ptr->voltNominalReading =22;// voltNominalReading;
        tmp_ptr->voltNonRecovLimitHigh =21 ;//voltNonRecovLimitHigh;


        tmp_ptr->next=NULL;

}

            return NULL;
        }

    }

    else {
        printf("\n I m here-------------in entry=NULL---\n\n");
//         SET_SNMP_ERROR(SNMPERR_UNKNOWN_OBJID);
        return NULL;
    }

}



This is wht i ve done to the generated template....I tried for very long
time but i m not able to resolve....  Any help will be of great help....its
urgent
