Hi
Your code would leak. You are creating an object and not freeing it.
The calling function that retrieves the result must handle the freeing
of the object.
It might be clearer if you just change the function to a procedure that
takes a TStringList as a parameter. i.e
//Replacement procedure
procedrue NewProc (sl :TStringList);
begin
sl.Add('Blah Blah');
end;
//Calling procedure
procedure call
var
AStringList : TStringList;
begin
AStringList := TStringList.Create;
try
NewProc(AStringLIst);
......
finally
AStringList.Free;
end;
end;
Hope that helps :)

Hi All. This is a question that might be infulenced by some serious
lack of sleep :-)
I have a funtion. Its return result is a TStringlist.
In my code I create a TStringlist then add my values to it, then pass
this to the RESULT varaible for the function.
Now, this is prob. an obvious answer than I prob. do actually know,
but if I got:-
sResult := TStringList.create;
sResult.add('blah');
Result:=sResult;
Then if I free sResult, then I loss the values I added, and the result
is empty as you would expect.
But the issue I have is, so if I DONT free sResults, what happens to
it? Surley it stays in memory,a dn I would end up with a memory leack
after repeaditive calls. Is that right? Or is because the variable is
function specific its free by default etc?
Its a basic question I know....but the more I thought about it the
more uncertain I became....I really need some sleep so that prob. the
real probelm :-)
