Hi Stefan,
is this a benchmark program or a complex program you are talking about.
If it is a benchmark, then it would be interesting to see the code,
because from my experience I doubt that Delphi produces better code than
fpc (in general it is the other way round). If it is a complex program,

Hi,
I'm have some tough times with arrays (I use them very little). With
trial and error I found that to use a pointer to an array of int32
values returned by a C API (Xlib to be exact), I have to define it as
follows in Object Pascal.
type
TAtomArray = array[0..0] of TAtom;
PAtomArray =
2010/9/22 Graeme Geldenhuys graemeg.li...@gmail.com:
type
TAtomArray = array[0..0] of TAtom;
PAtomArray = ^TAtomArray;
Now if I change TAtomArray to the follow, then my code doesn't work. :-)
TAtomArray = array of TAtom; // a dynamic array
So what exactly is the difference between
unsigned char **prop_return
you can actually define it as:
type
PAtom = ^TAtom;
PPAtom = ^PAtom;
and pass a PPAtom variable instead.

Hi,
While implementing drag-n-drop support in fpGUI, I created a
TfpgMimeData class. This class will hold various data items, and a
mime-type describing each of the data items. Obviously the
TfpgMimeData class should be able to handle any data type. So my
question is, what is a good universal
Personally, I would go for TMemoryStream

That would be my option too.
It's the most flexible.

Different choices. The question is if you want some typing (if only runtime)
and easy conversions, or e.g. have the data in a directly writable format.
Well, the data needs to be passed via Clipboard or Drag-n-Drop API's

Hi,
I'm not understand how to use unit Teventlog to no create each time a new
file but to append to an existing log file.
I want to do something like:
assign(f,filename);
if FileExists(filename) then Append(f)
else Rewrite(f);

I would first try a variant.
Just for getting the initial DND support to work under Xlib, I limited
myself to text types only, so choose variant as my storage type, but

No. But it allows you to keep text as text, not as streamed value.
I'll see how it goes, maybe I could store text as text, and binary as
binary - this will allow for the least amount of conversions. Plus the

This is currently not possible. Please file a feature request in the

Hi Adrian,
it is a scientific application that I have, which has about 2000 lines of code.
By extracting the most time consuming routine I now have 360 lines of code.
With this code I get the following runtime results:

I agree, that I also have seen examples where FPC pascal code is
about 10% faster than Delphi code.
So why does FPC pascal fail on this code?
At first sight it looks

I created a new project fpcprojects, with subproject fpprofiler.
You are listed as 'developer' for fpprofiler, that should be enough ?
