Re: how to Access Table data

Yes, not with the request-related structures, more from another function
like in the exampel below:



In the init function, we create a table:

// Initialize the contents of the table here
for (i = 0; i < RMH_NOTIFIED_NMS_IP_MAX_ENTRIES ; ++i)
{

// Allocate memory
entry = SNMP_MALLOC_TYPEDEF(struct mpbcRMHNotifiedNMSipAddressTable_entry);

// Return if Failed
if (!entry) return ;

// Create Row
row = netsnmp_tdata_create_row();
if (!row) {SNMP_FREE(entry);return ;}

row->data = entry;

entry->mpbcRMHNotifiedNMSipAddress_Index = i;

entry->mpbcRMHNotifiedNMSipAddress_IP = RMH_NOTIFIED_NMS_IP_DFT_IP_ADDR;

memset(entry->mpbcRMHNotifiedNMSipAddress_Description, 0,
sizeof(entry->mpbcRMHNotifiedNMSipAddress_Description));

entry->mpbcRMHNotifiedNMSipAddress_Description_len = 0;

entry->mpbcRMHNotifiedNMSipAddress_Enabled = 1;

// index the row

netsnmp_tdata_row_add_index( row, ASN_INTEGER, &i, sizeof(i));

// add the row

if (table_data) netsnmp_tdata_add_row( table_data, row );
}


Now in another function, we want to retrieve the values from the table :


void dump(void)
{

  for (i = 0; i < RMH_NOTIFIED_NMS_IP_MAX_ENTRIES ; ++i)
  {

// entry = ….(i) ????

index = entry->mpbcRMHNotifiedNMSipAddress_Index ;
ip_add= entry->mpbcRMHNotifiedNMSipAddress_IP ;
len = entry->mpbcRMHNotifiedNMSipAddress_Description_len ;
enable= entry->mpbcRMHNotifiedNMSipAddress_Enabled ;
  }
}
