Hi MF,
Thanks for your help.
That's shame I don't really understand how to use your example.
I guess your main point is taht I can get index values in handle_table().
static int
handle_table(netsnmp_mib_handler* handler,
netsnmp_handler_registration* reginfo,
netsnmp_agent_request_info* reqinfo,
netsnmp_request_info* requests)
{
netsnmp_request_info* r;
netsnmp_table_request_info* tri;
netsnmp_variable_list* vl;
for (r = requests; r; r = r->next) {
tri = netsnmp_extract_table_info(r);
if (!tri)
continue;
/* Here *vl contains the ip address and
* *vl->next_variable contains the port
* Note that this only extracts the indices, it is up to you
* to handle getnext requests properly!
*/
}
}
return SNMP_ERR_NOERROR;
}
But before I can get index values, I still need to get all external data for
XXXTable_get_first(next)_data_point to search.
Maybe I misunderstood your suggestion, could you explain more clearly?
Sorry that I am still very new to net-snmp.
Thanks in advance.
