Hi,
I am new to net-snmp (and snmp) so struggling a bit here.
I am successfully talking to an SNMP device and getting back some variables
which I can print out using the following code:
....init_snmp etc
then
sess_handle = snmp_open(&session);
pdu = snmp_pdu_create(SNMP_MSG_GET);
read_objid("Device::Alarm1.0", id_oid, &id_len);
snmp_add_null_var(pdu, id_oid, id_len);
read_objid("Device::Alarm2.0", id_oid, &id_len);
snmp_add_null_var(pdu, id_oid, id_len);
read_objid("Device::Alarm3.0", id_oid, &id_len);
snmp_add_null_var(pdu, id_oid, id_len);
read_objid("Device::Alarm4.0", id_oid, &id_len);
snmp_add_null_var(pdu, id_oid, id_len);
status = snmp_synch_response(sess_handle, pdu, &response);
if (status==0)
{
for(vars = response->variables; vars; vars = vars->next_variable)
{
print_variable(vars->name, vars->name_length, vars);
}
}
The above works fine.
What I am struggling with is getting the data out of the vars variable list. I
can get the type and value of the data but I don't seem to be able to get the
variable name back.
What I want to do is from the vars variable get back the objid eg Alarm1.0 for
each item in the list . How do I do this ?.
Many thanks for any assistance.
