The Network Monitoring API provides functions for getting network interface related information.

Required Header

#include <inm.h>

Overview

This set of functions are used to get network interface related information. To use this kind of APIs, You should create a inm handle using inm_initialize(). After that, you need to get link handle using inm_connection_get_link(), inm_link_clone(), inm_foreach_link(). You should destroy the created link handle if you do not need it anymore. You should destroy the created inm handle if you do not need it anymore.
