Btw: What are Tomoyo and Apparmour (I can imagine what the second one

Thanks.
So when changing/improving GetTempFileName we could also try to make
it compatible to such applications by creating a directory in TEMP for
the temporary file that contains the appname and the user.
The current implementation does just that. It uses GetTempDir which checks
TEMP and TMP (in that order), and if neither is set, uses /tmp.
Note also that you can hook in the temporary filename mechanism by setting
OnGetTempFile and doing it all yourself.
I'm aware of that (btw: is this OnGetTempFile possible on Windows as well?).
It should be ?
:)
But maybe we can use by default something like the following if
HAS_GETTEMPFILENAME is not set (pseudo code):
if OnGetTempFilename <> Nil then
OnGetTempFilename(Prefix)
else begin
dir := FindTempDir + PathDelim + GetAppName + '-' + GetUserName;
CreateTempFileInDir(dir, Prefix);
end;
* FindTempDir searches for a suitable environment var (TEMP, TMP, /tmp)
* GetAppName uses the GetAppName that is used for GetConfigDir as well (might
be named differently, I'm not looking at the source currently)
* GetUserName returns the name of the current logged on user (could be empty
if the username can not be found)
There is no user name info; at most the UID can be retrieved.
Secondly, the fallback should work on all platforms, so username etc. are
not relevant.
We're discussing a unix solution, so this will be implemented for unix only.
Michael.
