libsmi - Man Page

library to access SMI management information


This library contains functions that allow access to SMI management information stored in repositories that are managed by libsmi, currently directories containing SMIv1/v2 and SMIng MIB module files.

The libsmi API is defined in smi.h. Functions are documented in smi_config(3), smi_module(3), smi_node(3), smi_type(3), and smi_macro(3).

The purpose of libsmi is to separate the weird parsing and handling of MIB modules from management applications. MIB modules conforming to SMIv1, SMIv2 and SMIng - a new language for management information, developed originally at the Technical University of Braunschweig,  Germany - can be handled by libsmi.
