OK - three comments about your handler:
Firstly, it only deals with requests that contain a single varbind.
If the agent receives a request with two or more OIDs, both within
your table, then the second one won't be handled correctly.
You need to wrap the processing block within a loop such as follows:
switch (reqinfo->mode) {
case MODE_GET:
case MODE_GETNEXT:
for (request=requests; request; request=request->next) {
row = netsnmp_extract_table_row(request); // Note change
of variable!
}
Secondly, if you want to know the index value(s) from the incoming request,
this information is available automatically:
netsnmp_table_request_info *table_info =
netsnmp_extract_table_info(request);
DEBUGMSGTL(("DATA_SET_MIB_MODULE","%s\n", table_info->indexes->val.string));
Thirdly, I'm not entirely sure that the GETNEXT case will ever be triggered.
Many of the table helpers know which rows are valid, and will convert
a GETNEXT request into the equivalent GET request, and pass it through
to the MIB-specific handler as such.
I can't recall whether the data_set helper works this way, but I
wouldn't be at all surprised.
Try it - issue a "snmpgetnext" request for an OID within this table,
and see what index value gets passed into your handler routine.
