Where do you really n...

I want to improve the cross platform behavior of a java application. However, its test suite currently assumes the existence of the /tmp directory. What is the best equivalent location on the windows platform? N.B. I most definitely do not want to assume the user has admin rights but I do want it to work on at least XP, Vista & Windows7...

I need help of a real C guru to analyze a crash in my code. Not for fixing the crash; I can easily fix it, but before doing so I'd like to understand how this crash is even possible, as it seems totally impossible to me.
