Re: FW: Re: How can I extend a MIB with a subagentX

I've added in my registration of my table the creation of the rows:

int initGenServerTable
{

...

// Add a Row
netsnmp_table_row *row  = netsnmp_create_table_data_row();

u_long ind = 1;
netsnmp_table_row_add_index(row, ASN_UINTEGER, &ind, sizeof(ind));
netsnmp_set_row_column(row, 2, ASN_OCTET_STR,
                          "Test1", strlen("Test1"));
netsnmp_set_row_column(row, 3, ASN_OCTET_STR, "Test2",
                           strlen("Test2"));
netsnmp_set_row_column(row, 4, ASN_OCTET_STR,
                           "Test3", strlen("Test3"));

netsnmp_table_dataset_add_row(genServerTable, row);
}

When I execute my sub agent, I now have the following error:
illegal data attempted to be added to table (no index)genServerTable

although I set the index (variable ind) in the row of the table...

I hoped that management of the index of a table was managed by the net-snmp 
API. Must I manage it myself?

Thanks for your help.
