Is that your idea of *relatively* recent? :) I was thinking of a discussion a bit longer ago (but frankly, don't ask me to dig it up, I doubt I'd be able to). I haven't read the full thread above, in fact I stopped reading at ``` Arguments against: - it's uglier than "0", and more to type ``` because that sums up exactly how I think about the question. But in the end I only care that there are no chances of 32bit/64bit conflicts (I had some of those in code of my own, which led me to be almost religious about using NULL for pointers). I do have a bit of an issue with using a *Q_* prefix, as it suggests a Qt-specific type that should only be used in calls to Qt functions... - René J.V. ----------------------------------------------------------- This is an automatically generated e-mail.
