Tizen Native API  6.5
Network Monitoring Connection

The Network Monitoring API provides functions for getting connection information.

Required Header

#include <inm.h>

Overview

This set of functions is used to get connection information. To use This kind of APIs, You should create a inm handle using inm_initialize(). After that, you need to get connection handle using inm_get_current_connection(), inm_connection_clone(), inm_connection_iterator_next. You should destroy the created connection handle if you do not need it anymore. You should destroy the created inm handle if you do not need it anymore.
