In tiOPF (the code I linked too), GUID's are used as an OID (Object ID),
and normally stored in a database field of type char(36). The

Why are the { and } actually removed?
As far as I know they can be part of a filename on all OSes (or am I wrong?)

Thanks Graeme,Its like what I do so it seems Im doing OK. I looked at
the code and it seems it just remove { and }.

(I'm not sure if FPC 2.6.4 also some helpers for creating GUIDs)
This will work in FPC 2.6.4:
var
GUID : TGUID;
begin
if CreateGUID(GUID) = 0 then
begin
MyFileName := GuiDToString(Guid);
end;
You could strip the {, } and - if you want.

I wasn't aware that GetTempFileName isn't threadsafe.
(Are you sure your code is correct?)

This may be an appropriate use for EnterCriticalSection and
ExitCriticalSection, although why don't you just use a different
"prefix" in the call to GetTempFile for each thread.

This function returns a GUID value:

This is the class in tiOPF that uses GUID's. This class strips out the

Thank you Graeme. Can you point me to where this system
implemented in tiOPF?

I've used GUID's as temp file names in a CGI application for about 5

Hi,
I used GetTempFileName in a multi thread system and it causes problems
as you guess already. So the best way in my mind is using GUID and maybe
use it in a loop for checking not existing for extra safety. But I want
to know is there any clean implementation already that I dont know of?
