Introduction

The QNetworkInterface class provides a listing of the host's IP addresses and network interfaces.

QNetworkInterface represents one network interface attached to the host where the program is being run. Each network interface may contain zero or more IP addresses, each of which is optionally associated with a netmask and/or a broadcast address.

Preconditions

• Download and Install latest version Qt for Symbian - Installation packages which has links on how to install the latest version

Functions

• This convenience function returns all IP addresses found on the host machine.

QNetworkInterface *inter=new QNetWorkInterface();
inter->allAddresses();

• Returns a listing of all the network interfaces found on the host machine.

QNetworkInterface *inter=new QNetWorkInterface();
inter->allInterfaces();
