libsmi − 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.
