I stumbled into a problem I don't understand.
I'm developing a little program for an ftp client. In order to connect
to the site I need the site address from the site name, and the libc
gethostbyname() provides the required information.
gethostbyname returns a PHostEnt type which is declared

Should that not simply be
Addr := Pin_addr(HostEnt.h_addr^)
(if addr is a pointer)
or
addr:=Pin_addr(HostEnt.h_addr^)^

No chance. Addr is a pointer (of type Pin_addr)

works only if mode is Delphi. In objfpc it raises exactly the same

I found in a fpc program a statement sort of:
Type
TSomeType = (a,b,c)
TaType = set of TSometype
var
setA,setB: TaType;
.
*if setA * setB = [] then doSomething*;
which I found very smart to detect if the two sets have some common
elements, but I've been unable to find in the fpc docum

Hello,
Attached is a dirty implementation of "touch" for junctions

TTouchJunction = class(TCustomApplication)
I made a stupid error. My code:
TFileObj = Class(TObject)
[snip]
Size: Integer;
[snip]
end;
procedure TForm1.FillDir(FileData : TSearchRec);
...
FFIleObj.Size := FileData.Size;

but TSearchRec structure is:
TRawbyteSearchRec = Record

Size : Int64;

Yes. Assigning a 64bit integer to a 32bit one is fine as long as the
range is within bounds.
Range of a variable can only be checked at run time.
I can understand that. But the compiler generates quite a number of

If you compile with -CO, you should get at least a hint (if you enable

I believed that -Co was enough. I'll add -CO to the debug options.
Thanks.
