Having done some interaction with C libs IMHO the best option is not to free
the memory in pascal at all but doing it with the provided C functions (if the

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

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'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

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

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 type

you can actually define it as:
type
PAtom = ^TAtom;
PPAtom = ^PAtom;
and pass a PPAtom variable instead.

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.

TAtomArray = array[0..0] of TAtom;
