Re: How to write own application in c ?

Ok Benix, see ..

I am looking to
http://www.net-snmp.org/wiki/index.php/TUT:Writing_a_Subagent

I have downloaded NET-SNMP-TUTORIAL-MIB.

then I have done mib2c on node nstAgentSubagentObject and it has
generated nstAgentSubagentObject.c and nstAgentSubagentObject.h files.

Then I have created sub agent using net-snmp script as follows:

        * **% net-snmp-config --compile-subagent mysubagent
nstAgentSubagentObject.c*
It has generated mysubagent binary and GET, SET is working properly.

Now what should I do so that while I send GET request it should read some
file for value of variable and  for SET it write value of variable to that
file again.
