Do you anticipate any great Keith> changes to the API? I think the API is quite ok now, having the usual SMIv2 use cases in mind. There are lots of error detections that could be added to the parsers. Other things could be added like additional backends like an `SMI daemon', or fast access to an SMI database. But these things are not expected to change the API (significantly), and these changes are not more than dreams right now. On the other hand, we are research people. This means we have to invent new things. ;-) Based on our work on SMIng we want to add further information to the information model, which needs an interface in the API. But these changes that we expect in future releases will hopefully just *add* data structures and functions, so that existent code will continue to work without changes. In theory. ;-) Talking about the libsmi version, I'd say it's nothing more than a number, that should be incremented from time to time. I don't believe that a 1.0 release would stop us from any progress. ;-) I'm more concerned about too many changes in the API that could get application developers and users in trouble. -- !!

Keith> A little while ago I sent an addition to libsmi that provided Python Keith> bindings using SWIG. I'm not sure it that actually went through as I was Keith> having email problems. Did you see it? Yes, thanks Keith! I (as the mailinglist owner) just had to resubmit it to the list, since the list allows only members to post and your submission was sent from your new email adress before you resubscribed with your new address. You can check it yourself on the mailinglist archive at http://www.ibr.cs.tu-bs.de/projects/libsmi/mail/. Sorry, I did not yet find time to look at it and I'm not familiar with Python (yet?). I know that Juergen took a look and now understands your demand for an additional OID data structure. We think, this would help to use SWIG, but we also think that it is more important to keep the core C API not overloaded with nested data structures.

Did I get you right?... You wish to have a way to specify a node and search for a specific node by a given name, e.g. search for sysDescr underneath 1.3.6.1.2? Saurabh> From my understanding of the API, there isn't a way to do Saurabh> this? Am I right? If I understand your wish correctly, you are right. This is not possible. Saurabh> If so, would the maintainers consider adding such an Saurabh> interface in a future release? I think, the only exact way to search for a node is by giving a module and a name. A subtree root node is no good choice for limiting the namespace of object identifiers, since (a) it is not capable to preclude the possibility of a name duplicate and (b) it does not (gernerally) allow to limit the set of nodes to semantic groups like a module does. So, I have a preference not to include such a function in the API. -- !! This message is brought to you via the `libsmi' mailing list. !! Please do not reply to this message to unsubscribe.

Searching for objects
by jang＠eis.comm.mot.com 30 Mar '00

I know from the description of the API in smi_node(3) that one can retrieve information about an object given its name either by searching the entire MIB tree or by containing the search to a specific module. The application for which I plan on using libsmi would benefit from the convenience of being able to specify the root of a subtree to which the search for the given object should be restriced. >From my understanding of the API, there isn't a way to do this? Am I right? If so, would the maintainers consider adding such an interface in a future release?

RE: [libsmi] C++ style comment in libsmi-0.2

Yes, later versions do accept C++ comments. It is still bad style to use C++ comments in C.

Re: [libsmi] Beginnings of C++ interface to libsmi.

David Reeder writes: David> It was so long ago you may have forgotten, but follows is the David> beginnings of a C++ interface to the libsmi package. [...] Great! How should we proceed? My current preference is to let your C++ interface live besides libsmi as a separate package, because I'm not familiar with it (and even not familiar with C++ ;-). When some time went by and people would like to see both packages integrated, we might decide to do so. What do you think? May I put your tarball to our FTP archive?

I'm fine with these changes. I've applied them to the libsmi CVS module. -- !! This message is brought to you via the `libsmi' mailing list. !! Please do not reply to this message to unsubscribe.
