Hi,
Thanks for answering my previous questions. Now please help me solve a
problem I am facing.
I have created an application that will query a network device every 10
sec.
And my app will also sent some critical info to a network server in
every 200 milliseconds.
A loop-timer mechanism will take care of this, if no functions are
blocking calls.
So I have used "snmp_async_send" API to query the device, so that it
will not block my application flow.
And everything worked fine, for some time.
But recently I have found that when the n/w device to be queried, is
powered off; this API will block my application flow for some 2 sec, and
returns a timeout error.
But by this time the window for sending the critical info to the server
will be over.
So my app fails..
The waiting for timeout may be causing this problem.
Is there any way to make this function (snmp_async_send) truly
asynchronous?
That means, is it possible to make this function to just send the PDU
and return, and to capture the error in the response callback?
I think somebody has also asked this question, but it remains
unanswered.
And I would like to know whether there is a command known as TEST, which
is to be used before SNMPSET.
Somebody told me, it is better to issue a TEST before a SET.
If true, can you point me to any tutorials/references for that.
Thanks and regards,
Basil Joseph.
