I had to create a function to do this so I did it like this:

int QStringToTCharBuffer(QString buffer, TCHAR* Array){
    return buffer.toWCharArray(Array);
}

The bad part is that the caller has to create the TCHAR* large enough
to hold the QString, and set the terminator.

I guess, the other option would be to return a std::wstring and have the caller do .c_str().

The other way around is fine because we can return a QString.
