I want to attach an ifstream to cin, is this possible with
g++ (version 2.2.2) ?

What I want to do is:

void SomeFunction(string szFileName)
{
    ifstream InStream;

    if (szFileName == "")
    {
        InStream.attach(0);                 // attach InStream to cin
    }
    else
    {
        InStream.open(szFileName, ios::in); // attach InStream to szFileName
    }

    ...
}

Thanks in advance,
