How to acquire host IP within program

[CrazYmonkeY159]

Hello all.

I am currently working on a mini project for Uni. Ive run into a little problem. Im currently coding a simple tcpserver application

I do not know how to obtain my PC's current IP (Ethernet, assume the PC only has 1 Network interface, if that makes a difference)

something like getting your IP from cmd->"ipconfig /all"

reasons for this being I want the program to display its own IP so that I can enter this IP into connecting clients.

If it matters, im using C++ in Windows using the Qt framework, after some googling it seems as if Qt has no such method of doing what Im looking for, any ideas people? thanks in advance

I'm not a C++ guy but this looks like what you need:

EDIT: I do realize you are using QT, but I am presuming you can include Winsock alongside?

I think the function you're looking for is:

QHostAddress QTcpServer::serverAddress () const
and
QString QHostAddress::toString () const

Yeah I tried this innitially and it returns 0.0.0.0, tried this on multiple PCs...

0.0.0.0

This means "all network interfaces" and although I'm not a QT expert I think that class is used to create a server socket and not for obtaining the PCs IP address. The way I read the documentation, you can construct an instance of this class and it will listen for connection on a particular port and IP address.
