The general problem is to get a module&identifier out of an OID. Libsmi can solve this query only for the modules that have been loaded. If you know the set of MIB modules that contain all the required information, then smiLoadModule() all those modules, then smiGetNodeByOID() the SmiNode of each notification OID you receive, and walk through the varbinds.
i have don't the smiGetNodeByOID, when i print node->name, the only thing that i get is iso., i only get the first piece of the OID. What should i use to walk through?, i tried smiGetNextNode(node, node->nodekind), but all i get is a seg fault.
Unfortunately, there is no tutorial for libsmi, but the man pages and the programs in the tools directory may help to get on the right track.

The formal way to learn about SNMP is to read the appropriate RFCs. The (in my opinion) in the first step more efficient way, is to read a good book, and then use the RFCs as a reference. What `good' is, depends a little on your goal. My starting point was a former revision of:
@Book{Ros96, author = "M. T. Rose", title = "The Simple Book -- An Introduction to Internet Management, Revised Second Edition", edition = "2", publisher = "Prentice Hall", year = "1996", ISBN = "0-13-451659-1", }
