Template:FAQ:Coding

1. How do I write C code to integrate with the agent?
2. How does the agent fetch the value of a MIB variable from the system?
3. Mib2c complains about a missing "mib reference" - what does this mean?
4. Mib2c complains about not having a "valid OID" - what does this mean?
5. Why doesn't mib2c like the MIB file I'm giving it?
6. Mib2c ignores my MIB and generates a pair of 'mib-2' code files. Why?
7. Mib2c complains about "configuration files". What's this for?
8. What's the difference between the various mib2c configuration files?
9. Which mib2c configuration file should I use?
10. How can I have mib2c generate code for both scalars and tables?
11. Are there any examples, or documentation?
12. Where should I put the files produced by 'mib2c'?
13. I've created a new module with 'mib2c' but it doesn't work. Why not?
14. I've added my code to this template and it still doesn't work. Why not?
15. Mib2c only handles a single table in my MIB. How can I fix this?
16. Why does the iterator call my get_{first,next} routines so often?
17. How can I support a large table, with more than 256 column objects?
18. How can I get the agent to generate a trap (or inform)?
19. How can I get the agent to send an SNMPv1 (or SNMPv2c) trap?
20. How can I get the agent to include varbinds with an SNMPv1 trap?
21. How can I get the agent to send an SNMPv1 enterprise-specific trap?
22. How can I get the agent to send an SNMPv3 trap (or inform)?
23. Why does calling 'send_v2trap' generate an SNMPv1 trap (or vice versa)?
24. What if I'm using an AgentX sub-agent instead?
25. How can I register a MIB module in a different (SNMPv3) context?
