Okay to move an "object" will-nilly?

[Frederick Gotham]

(My dialect of English seems to puzzle people at times, so I'll first
clarify a few terms which I use in the following post:)

(1) By "domestic", I mean "ordinary, run-of-the-mill, not
extraordinary or strange".

(2) By "willy-nilly", I mean something along the lines of
"haphazardly", but without any sense of recklessness (i.e. gleefully
doing something without expecting any sort of negative effect, even
though there may in fact be a negative effect), e.g. "A child would drink
a glass of liquid left on the kitchen table willy-nilly, blissfully
ignorant as to whether it contained bleach".

================================================== ====

Okay I'll try to keep the C++ part brief (and yes, my eventual question
is about C):

In C++, there are things called objects. They behave just like
variables, but special things happen when they're created, destroyed,
copied, assigned to, etc.. (specifically, the programmer can specify code
which is to be executed).

If you want to copy an object in C++, is it ill-advised to simply do:

ArbitraryClass original_object;

ArbitraryClass *p = malloc( sizeof *p );

memcpy( p, &original_object, sizeof original_object );
The reason why it's il-advised is that when an object is created, code
can be executed via a "constructor" which may result in the acquisition
of resources such as dynamically allocated memory. If we perform a
"shallow copy" by using "memcpy", then the resulting copy is using the
same resources as the original (when in reality, we want it to get its
own). The matter is remedied by using a copy-constructor... but I won't
get into that here.

Anyway, notwithstanding any of that, I thought it would still be OK in
C++ to move an object in memory, i.e. simply re-locate it. This would
involve memcpy'ing its bytes to a different location and simply not
making any further use of the original. I was told however that this also
is il-advised in C++, because the object's address may be of some
significance to its internal workings (i.e. the special code that gets
executed when you assign to it, destroy it, etc.). A prime example would
be an object which contains a buffer, and which also contains a pointer
to the current position in the buffer, something like:

struct StringStream {

char buffer[1024];

char *p_pos; /* Points to an element of buffer */

};

If we were to move an object of the type "StringStream", then "p_pos"
would effectively become corrupt.

So what's the significance of this?

Recently, I wrote a funky kind of algorithm for sorting an array (whether
it be an array of char's, int's, double's or perhaps a C++ class type),
and the algorithm moved objects around willy-nilly by using memcpy and
discarding the original. However, my algorithm was "broken" in the sense
that it would corrupt objects whose address was of some significance to
their internal workings.

Hence, there is an accepted etiquette in C++ that, when writing re-usable
code such as a sorting algorithm, you DON'T just re-locate objects willy-
nilly, but rather you've to resort to more elustrious means.

My question is:
Does any such etiquette exist in C? If I were writing a domestic
sorting algorithm in C, would it be acceptable for me to re-locate the
objects willy-nilly?

Provided nothing was relying on the previously established order of the
the array, yeah sure why not?

Though I should add that even in C++ if you had an array of class
instances you could sort them if you had overloaded the comparison and
assignment operators.

In C
int int_object;
is a declaration of an object named int_object.
I believe that's also true in C++.

FILE type objects are like that in C.

When there's a problem with copying or overwriting objects,
such as with FILE type objects,
and the objects refered to by string literals,
you would be better off sorting an array of pointers to the objects.

Depends on the objects and their usage. In general, the answer is no.

Not only the objects may contain pointers that would be invalidated by
the relocation, (as in your own StringStream example,) their addresses
could also be stored in pointers somewhere else in the code and those
would be invalidated.

One more issue: How would you handle the relocation of objects
residing in dynamically allocated memory, either explicitly by calling
malloc() or because the objects were declared as automatic variables?
(The same for mixture of static and dynamic objects.)

OTOH, if you changed p_pos to be the size_t displacement into the
buffer of the (first) char of interest, then you may very well be able
to relocate StringStream(s) at will.

The C qsort() function does exactly this. If you are sorting an array
of objects, the objects in the array must be move safe. If they are
not move safe, then you will have problems using them after you have
sorted them with qsort(), unless you have the degenerate case where
the array was already sorted so no swaps were performed by the sort.

In the case of your example StringStream structure, it would not be
safe to sort them by qsort(), nor would it be safe to sort them by any
other means that involved swapping.

As others have mentioned, you can define an array of pointers to the
structures, then sort this index array with another level of
indirection.

So C, just like C++, allows you to do some things that might not be
safe. You can use memcpy() or memmove() on C objects, just as you can
on POD objects in C++. It is up to the programmer to determine if the
internal structure of those objects makes the operation useful.

You haven't any choice, since that's what sorting /does/.

But if you have "deep" data, you'd be better off sorting pointers.

I think he should have said "idiolect" rather than "dialect": I too
wouldn't interpret "domestic" that way (although I can see it being
used that way).

English as spoken in Dublin in Ireland. It's true that some of our
grammar and phrases are influenced by the Irish language, but I think our
use of "domestic" is pure English as I can't think off-hand of an
equivalent term in Irish.

We also use the term "domesticated" to indicate that an animal has been
tamed. For instance:

-John was attacked by dogs down by the lake.
-Were they wild dogs?
-No, domesticated.
All the forms of "domestic" indicate (to us in anyway) something which is
commonplace and not extraordinary.

I disagree. It seems blatantly obvious that people are engaging in this

"domestic" is a shortened form of the Latin "domesticus" which is
derived from "domus" meaning house. The dogs in the example above
are domesticated because they live around humans, around human
habitation. Things likely to be found around houses are more likely
to be commonplace and not extraordinary, but it is possible, for example,
to have a domesticated leopard or boa constrictor.

In the Oxford English Dictionary (oed.com), *none* of the shades of
meaning of "domestic" (including in the latest drafts) is listed as
pertaining to that which is commonplace and ordinary.

Thus, I would judge that your use of "domestic" is a -relatively-
localized extension, which would be likely to confuse most people.

Actually, this thread has opened my eyes to something.

I've never thought of the word "domestic" as meaning "from home" or "from

American's tend to use the word.

Take the term, "domestic violence"; I always used to think that it meant

I took you up on your statement that the definition of domestic has a
different meaning in Ireland by searching for the word on Ireland-only
websites, after reviewing some several dozen uses of the word I am
beginning to think that you are alone in the confusion of its usage as
I didn't see one instance of it used the way you have described, either
that or it has an extremely localized connotation.

Right. It's another oxymoron, since the phrase is applied only to
violence between members of a family. I've never heard of the term
used to describe violent treatment of intruders.

It really isn't, though. ;)
We also use the term "domesticated" to indicate that an animal has been

Exactly, "brought into the home." You can look it up in the OED if
you want the Proper English definition. "Domestic" means "of the

Right. It's another oxymoron,

I thought an "oxymoron" was a phrase where the terms were contradictory,
like "colourless green" or "beautifully ugly" [1]; I don't see anything
contradictory between "domestic" and "violence". (Alas.)

[1] Not to be confused with "military intelligence", which isn't an
oxymoron, but where /describing/ as such implies a contradiction
suited to the speaker's purposes. So I am led to believe.

It may be pure Ireland-mutated English, but as normal English I'm afraid
both of those are beyond the pale.

It's a play on the word "intelligence", of course. I spent a few years
in MI and those on the inside would generally agree that it _is_ an
oxymoron. :-)

That is my (and most dictionaries) definition. E.g. "Of or relating to
the family or household." The concept is scaled up to include larger
"families", thus we have domestic wine and domestic foodcrops, as
opposed to imported.

Quite literally, as it happens. I assume you know where the expression
"beyond the pale" comes from? :-)

The word has (at least) two distinct meanings:
1) The ability (to think/reason/etc - generally, acquire
knowledge/information). This is the most common sense.
2) knowledge/information itself (as a commodity). This is the
sense in which the term MI is used.

Agreed. First, in the context of the OP (in both senses of that term),
it was certainly an odd choice of word (particularly in the
anal-retentive environment known as clc), but we all got a laugh out of it.
And that's the important thing!

Second, m-w gives this def'n:

4 : devoted to home duties and pleasures <leading a quietly domestic life>

which I could imagine as being "almost there". I would *not* be surprised
to learn that this is, in fact, acceptable usage in Dublin Irish English.

If I were writing a domestic sorting algorithm in C, would it be
acceptable for me to re-locate the objects willy-nilly?

No:
1) It could corrupt the object (eg. if it were a struct
StringStream).
2) There may be pointers to the current objects.
3) You don't know how the objects should be allocated.

I've never thought of the word "domestic" as meaning "from home" or "from
this nation or country"... and only now do I see that that's how
American's tend to use the word.

Take the term, "domestic violence"; I always used to think that it meant
"common, everyday violence", but now it seems as though it actually means
"violence in the home". Am I right?

Another common usage is "domestic terminal" vs. "international
terminal" at the airport.

"malloc" returns a pointer to a byte in memory which is a suitable starting
location for an object of any type.

But yes, if I were to use a simple local automatic storage char array, I'd be
in trouble.

They could also be allocated with a custom allocator, and/or
the system might not support malloc.
