NULL again

[William E. Davidsen Jr]

  I swear that the world is full of assholes who take something I wote
out of context to prove how smart they are. Here's another one!

  Do you see a statement that says they are portable? Do you??!! If you
have read the entire discussion instead trying to impress us with you
briliance, you would see that the answer was to someone who said that
(a) NULL should always be 0, and (b) if it isn't the compiler is broken,
therefore (c) assuming NULL is 0 will be portable.

  I was pointing out that NULL is not portably 0 because (a) there are
lots of implementation which don't do it that way (real world) and (b)
dbANS says it will evaluate to a "pointer constant." I quoted section,
page, and line number showing this, making only the point that NULL
isn't zero.

  When I spend the time writing a carefully constructed reply, looking up
references, showing someone where their logic is wrong, and being polite
in the process, the least you can do is to read the whole posting before
trying to show off.

  I'm really impressed with your cute saying to put over my terminal,
here's one for you:

              Before you flame be sure you understand the
                                PROBLEM
                                and the
                                SOLUTION

  I've been trying very hard to be polite in my postings the last three
years, but I didn't try very hard in this one, and my personal mail
message to you represents not trying at all.
