Now the comparison of these pointers is UB in C but in this case
it's the only way to do it. What would you do in such a situation
when you work on a project that has to be finished shortly?
No, it's not UB. Those are equality tests, not relative tests.
Thanks for clearing that up, funny thing is I thought this was the case
because somebody in this group said this. I thought usenet was always
correct :(
Shame I cant find that post on google
