Hi,
I'm using FPC 2.7.1 under 64-bit FreeBSD 9.1. I have to use 2.7.1
(updated about a week ago), so I could get the fixes for threading and
memory corruption under FreeBSD (disussed a while back on mailing list).
Anyway, every now and again my projects (a few of them) fail to link as

Hi All,
I have two simple questions:
1) As far as I know class variables in FPC are automatic initialize to the
NULL value (e.g. 0 or or whatever), does that include dynamic arrays?
e.g.
TMyClass = class
myarray: array[0..100] of Integer;
end;
will myarray be initialized to nil?
2)
Sorry the array should be dynamic, without [0..100].

Hi There,
Is it possible for class helpers to be selective? i.e. attach to a
specific object of that class, but not every instance? This would be
useful for behavior injection.
Thanks

You could answer such questions yourself:

Yes, in that case it will be Nil (Note: in the static case the elements of
the array would be 0).

2) After SetLength(myarray, 0), is myarray nil or pointing to some
invalid address?
It will be Nil. An equivalent alternative would be:
MyArray := Nil;

No, this is not possible.

So, it is even OK to use SetLength() on static arrays? interesting.

I don't know if it is possible, but how about using fpSignal()? See

The document said it is deprecated? Also, I want this to be cross
platform, not for unix only. The use case is:
try
buf := GetMemory(1024);
size := 10240;
stream.Read(buf^, size);
except

I vote for Traits. This will make FP more flexible... As a matter of
fact, I was surprised to see operator overloading being implemented in
pascal, which was a feature I like in C++, although I have never write a
program more complex than cout Hello World in that magnificent
language. :-)
Is there a complete list of reference counted variables in FP? e.g.
dynamic arrays are ref-counted. but are variables allocated by New()
ref-counted?
My use case is:

p: = New(PMyRecord);
MyListView.Item[0].Data = p;
MyListView.Item[0].Delete; -- Do I need to
