[DUG] Dumb Friday Question

[Xander (GMail)]

Jeremy,

 

If the function returns a TStringList then it should be the responsibility
of the caller of that function to FREE the returned TStringList after it has
finished using it. You cannot free it inside the function.

 

Regards

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 :-)

 

Jeremy
