Re: non contiguous column index

I must be doing something incorreclty.Based on an example I found in the 
mailing list

I have tried the following:
#if 0
    table_info->min_column = 1;
    table_info->max_column = 13;
#else
    col_info = SNMP_MALLOC_TYPEDEF(netsnmp_column_info);
    col_info->isRange = 1;
    col_info->details.range[0] = 1;
    col_info->details.range[1] = 4;
    col_info->next = SNMP_MALLOC_TYPEDEF(netsnmp_column_info);
    col_info->isRange = 1;
    col_info->details.range[0] = 6;
    col_info->details.range[1] = 8;
    col_info->next = SNMP_MALLOC_TYPEDEF(netsnmp_column_info);
    col_info->isRange = 1;
    col_info->details.range[0] = 11;
    col_info->details.range[1] = 13;
    col_info->next = NULL;

    table_info->valid_columns = col_info;
#endif



Now in the table handler the column number is set to -1;
table_info->number_indexes is set to 0 while 
table_info->reg_info->number_indexes is set to 1
and table_info->reg_info->valid_columns is NULL.

Is there a missing function call in my table registration?
