#ifdef and so on.

Hi, I'm looking for a tutorial about #ifdef and those. But I have some problems finding one, because fx google seem to be finding everything else.. So kind of help will be very appreciated, but a link for me to study would be the greatest :D

Thanks in advance..

Did you try searching: "c++ preprocessor directives"?

No, because I didn't know that name. I'll try that :)

And thx :)
I found that I was looking for :D
