One way to implement this is to have a structure that has backup values stored, such that you have the object you want to read and write, OID, and an placeholder old_OID.
You can then iterate over the request varbinds, storing any old values until such time as you commit them, or undo the set.

Subject: State Information in smnpset: where to keep it?

Hello,
I am working on an AgentX agent to run in an embedded beast, and I seem to have things working.
But I am worried about the state machine used in setting a variable. How do I save state information between MODE_SET_RESERVE1 and MODE_SET_RESERVE2, MODE_SET_COMMIT?
- reginfo->my_reg_void seems to be per-registration not per-request.
- my_void is mentioned in old mailing list traffic but doesn't seem to exist anymore
- storing in static variables in my handler functions seems to work, but is it safe?
Thanks,
-kb
