network ports up/down

[kemp]

Hi!

my application has to check on the local machne if an UDP port is up or down.

How can i get the status of an UDP port?

I have tried this with


QUdpSocket udpSocket;
if(udpSocket.bind(address,port))
{
return PORT_UP;
}
else
{
return PORT_DOWN;
}

but i don't know if this is the right solution for the problem.

solved with

QAbstractSocket::connectToHost

and

QAbstractSocket::SocketState
