Implementing persistant data.

Hi All ,

I was trying to implement persistant data in net-snmp . I just want to read the data from my custom config file .

I am using the function 
register_config_handler("filename","token name" , ptr to parser function ,  NULL , NULL );

As soon as it reads the token from the file given , it has to call the parser function which will get the token and its value as its paramters . But in my code the parser function is not being called at all .


Need help from any1 who has worked on the same .
