problemes with the code created by mib2c.iterate.conf

[正 王]

Hi,all
     I create netSnmpIETFWGTable.c, netSnmpIETFWGTable.h using NET-SNMP-EXAMPLES-MIB by
running mib2c mib2c.iterate.conf
     I initialize table data in netSnmpIETFWGTable_get_first_data_point(),

////code
  struct netSnmpIETFWGTable_entry *tmp;
 
    while (netSnmpIETFWGTable_head)/*clean link list begin*/
        {

             tmp=netSnmpIETFWGTable_head->next;

             netSnmpIETFWGTable_removeEntry(netSnmpIETFWGTable_head);

             netSnmpIETFWGTable_head=tmp;

         }/*clean link list end*/

             

    tmp=SNMP_MALLOC_TYPEDEF(struct netSnmpIETFWGTable_entry);
    tmp->next=NULL;

    // add values to link 
    memset(tmp->nsIETFWGName, 0, 64);
    memcpy(tmp->nsIETFWGName, "snmpv3", 6);
    memset(tmp->nsIETFWGChair1, 0, 64);
    memcpy(tmp->nsIETFWGChair1, "Russ Mundy", 10);
    memset(tmp->nsIETFWGChair2, 0, 64);
    memcpy(tmp->nsIETFWGChair2, "David", 5);
 
    netSnmpIETFWGTable_createEntry(tmp->nsIETFWGName,

                                                         tmp->nsIETFWGChair1,
                                                         tmp->nsIETFWGChair2);
    SNMP_FREE(tmp);
////

    but when I want to get infoes by snmpwalk, but the value of

    table_info->colnum is 0 in the netSnmpIETFWGTable_handler(), and the return of snm pwalk is

" NET-SNMP-EXAMPLES-MIB::netSnmpIETFWGTable = No Such Object available on this agent at this OID"

 

////code
    netsnmp_request_info *request;
    netsnmp_table_request_info *table_info;
    struct netSnmpIETFWGTable_entry *table_entry;

    switch (reqinfo->mode) {
        /*
         * Read-support (also covers GetNext requests)
         */
    case MODE_GET:
        for (request = requests; request; request = request->next) {
            table_entry = (struct netSnmpIETFWGTable_entry *)
                netsnmp_extract_iterator_context(request);
            table_info = netsnmp_extract_table_info(request);

 

           /////here the value of table_info->colnum is 0
    switch (table_info->colnum) {
            case COLUMN_NSIETFWGCHAIR1:
                snmp_set_var_typed_value(request->requestvb, ASN_OCTET_STR,
                                         table_entry->nsIETFWGChair1,
                                         sizeof(table_entry->
                                                nsIETFWGChair1));
     snmp_log(LOG_ERR, "%s\r\n", table_entry->nsIETFWGChair1);
                break;
            case COLUMN_NSIETFWGCHAIR2:
                snmp_set_var_typed_value(request->requestvb, ASN_OCTET_STR,
                                         table_entry->nsIETFWGChair2,
                                         sizeof(table_entry->
                                                nsIETFWGChair2));
    snmp_log(LOG_ERR, "%s\r\n", table_entry->nsIETFWGChair2);
                break;
            }
        }
        break;

 How can I do?
 Thanks for any comments and suggestions!
