I don't think I understand. I am not interating over anything now, I am just
getting handle_somevariableofmine() calls and I look reqinfo->mode to see what
I am supposed to do. (I have a single template I feed to mib2c and it produces
a long file of repetitious code, and I figure that is the way I am supposed to
do things.)
In each handler function, when I see the MODE_SET_RESERVE1, I do my
pre-flighting to make sure the details make sense, then when I get the
MODE_SET_COMMIT I actually store the data. I was thinking that intermediate
results from the MODE_SET_RESERVE1 step could be reused in the MODE_SET_COMMIT.
(I could just duplicate that work in COMMIT, it has no side effects, but that
seems wrong.)
Is there something I should already be iterating over or are you describing an
iteration I would do to connect up RESERVE1 stuff with COMMIT stuff?
Right now I am just using statics and it seems that net-snmp does not reenter
my code and mix calls from more than one snmpset, but I don't know that this is
guaranteed.
I was expecting I would allocate a structure in RESERVE1 and hang it from
something in reqinfo, then in later calls refer to it, and in COMMIT or FREE,
deallocate it. But I don't see where to hang it.
Thanks,

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.

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
