Monitoring Network Connectivity

The Nickvision::Network::NetworkMonitor class provides an easy to use API to monitor for changes in the system's network connectivity.

Take the following program that checks the network status on startup and watches for changes:

using namespace Nickvision::Network;
 
void onNetChanged(const NetworkStateChangedEventArgs& e)
{
    std::cout << "Network state changed: " << (int)e.getState() << std::endl;
}
 
int main()
{
    NetworkMonitor netmon;
    netmon.stateChanged() += onNetChanged;
    //Have to check initial state
    if(netmon.getConnectedState() == NetworkState::ConnectedGlobal)
    {
        std::cout << "Connected to internet on startup." << std::endl;
    }
    else
    {
        std::cout << "No connectivity on startup." << std::endl;
    }
    std::cout << "Listening for changes..." << std::endl;
    while(true)
    {
        std::this_thread::sleep_for(std::chrono::milliseconds(100));
    }
}
