Thank you Dave for your fast reply.
First of all, I'm trying to finish this project for over 2 weeks, but I didn't want to ask for any help.I've tried many different ways to approach this problem, using different frameworks (mib2c.array-list and the other types).
Do you think that it will be a problem even if I want just to use only those 2 columns? Should I try to make a new MIB file from scratch? I have attached (in the previous mail) a new mib file that I wrote 10 minutes ago. It has one scalar object, for the number of indexes, and a table prvTable with an index and another 3 columnar objects.
If you say that if I use any 5.x-based documentation should be ok? Because I will try to use the following one: http://www.net-snmp.org/tutorial/tutorial-5/toolkit/mfd/if-mib/ifTable/index.html. I saw that in my 5.5 version there is a "container_load" that is a little bit different from "_cache_load" from the tutorial.
Assuming that the Mib file that I wrote is ok and I'm gonna use the mfd framework, can you help me with the steps (or/with the code) for binding the variable with a value for the begining a static one (Static char atr="1234")? I will appreciate your effort and you will help me a lot because even I know the C language, the way the framework generates the files confuses me.
Thank you again for your reply and for your consideration
PS: I don't know why, but when I'm sending an email with an attached file on your site is displayed only one of them. (the text or the attached file).
