How do I add new rows to a table_data table?

I've generated a table using mib2c.table_data.conf which works fine for
getting and setting existing rows, but segfaults when the user tries to
create a new row (because the row is null in the request info).

What is the correct way to implement this in the table handler?  At the
moment I've hacked together the following, after scouring the net-snmp
source code.  It is sort of working, but I'm not that confident about it.

[code snippet -- error handling ommitted]
    case MODE_SET_RESERVE1:
        for (request=requests; request; request=request->next) {
            table_data  = netsnmp_tdata_extract_table(request);
            table_info  = netsnmp_extract_table_info(request);
            table_row   = netsnmp_tdata_extract_row(request);
            table_entry = (struct myTable_entry *)
                              netsnmp_tdata_extract_entry(request);

            if (!table_entry) {
                table_entry = SNMP_MALLOC_TYPEDEF(struct myTable_entry);

                if (!table_row)
                    table_row = netsnmp_tdata_create_row();
                table_row->indexes =
                             snmp_clone_varbind(table_info->indexes);
                table_row->data = table_entry;
                netsnmp_tdata_add_row(table_data, table_row);
                netsnmp_insert_tdata_row(request, table_row);
[/code snippet]

I know this isn't working properly as, despite adding the new row to the
request, the code is triggered for every OID in the set request rather
than just the first.

Ideally, I don't want to create the row until I've processed all the
columns, so I can validate the data first.
