news.individial .net doesn't let you post from a web browser.

Many computers have a web browser and not a usenet client,
and many computers do not give administrator access to the
user (eg. at an internet cafe). Google Groups would be good
if it didn't fuck up the formatting.

Or lead you in to posting twice? :-P

Seriously, I know that in some situations one does not have the option
of a real news client, but a lot of people (not you) use Google because
they don't know there is any other option.

Of course, all the Google users could try complaining about Google
screwing up the formatting. They *might* do something about it.

Given the people who you're encouraging to killfile you are the people who
know the answers to your question, its more likely you;ll get a bunch of
nonsense answers. Your decision tho.

Well, look at this thread. Most people have offered help, either after
complaining that I didn't read the FAQ or not. All help offered,
however, has been correct and contains a high degree of correlation
between them.

Stuff and nonsense. The Standard says:


4.10.3.1 The calloc function

[...]

Returns

The calloc function returns either a null pointer or a pointer to
the allocated space.


As you can see, the calloc function certainly can generate a null
pointer if necessary.

That's what I thought at first, too, but it was pretty clear to
me, on rereading, that "Old Wolf" actually meant that any
pointers *inside the allocated region* are not necessarily set to
null by calloc(). He could certainly have phrased it better.

If he meant that all-bits-zero doesn't necessarily mean NULL, then
I owe him an apology. If he didn't, I don't. :-)

The question then is whether you consider this sufficient justification
for abusing the newsgroup.

Yes, asking a question that is answered in the FAQ IS abuse, although
there are certainly worse forms. FAQs exists so that the same topics don't
have to be discussed over and over again in the newsgroup. As such looking
at them before posting should not be considered optional. Of course there
is nothing wrong with discussing the answer in the FAQ further.

*shrug*. And you've also been killfiled by several regulars. You're losing
out so far, IMHO.

The first is unascertainable if you're asking offtopic questions here, and
the second could merely mean you got a load of "me too" answers from
people trying to look clever, or who also read the wrong book.

I repeat: *shrug*.

What Trollsdale calls an "indigenous troll", humans call a "regular" or
a "clueful poster".
