The 'lnbCustom2Table_get_next_data_point' routine needs to return NULL
when it gets to the end of your table:
> netsnmp_variable_list *
> lnbCustom2Table_get_next_data_point(
> void **my_loop_context,
> void **my_data_context,
> netsnmp_variable_list *put_index_data,
> netsnmp_iterator_info *mydata)
> {
> int i = (int)*my_loop_context;
> DEBUGMSGTL(("lnbCustom2Table",
> "lnbCustom2Table_get_next_data_point \n"));
I'd be tempted for this debug statement to include the current index
value. I.e.
DEBUGMSGTL(("lnbCustom2Table",
"lnbCustom2Table_get_next_data_point %d\n", i ));
> netsnmp_variable_list *vptr;
> vptr = put_index_data;
>
> snmp_set_var_value(vptr,
> (u_char *)&custom2table[i].loBand,
> sizeof(custom2table[i].loBand) );
How big is "custom2table" ?
What happens when you run off the end of it?
You probably need something like:
if ( i > MAX_custom2table_INDEX )
return NULL;
(coming *before* the snmp_set_var_value statement above)
> DEBUGMSGTL(("lnbCustom2Table",
> "lnbCustom2Table_get_next_data_point loBand\n"));
>
> *my_data_context = (void*)&custom2table[i];
> *my_loop_context = (void*)++i;
>
> DEBUGMSGTL(("lnbCustom2Table",
> "lnbCustom2Table_get_next_data_point end\n"));
I probably wouldn't bother with those two debug statements either.
A single debug output, containing all of the useful information about
this particular run is likely to prove clearer.
