Hi is the following allowed or will it cause problems:

type
PObj = ^TObj;
TObj = object
  constructor Init;
end;
var
 Obj : PObj;
begin
 Obj := new(PObj, Init);
 FreeMem(Obj); // This is the line I wonder about.
end;

I compiled this and it doesn't throw any exceptions.

Should I only use Dispose(Obj) ?

Maybe Dispose can call a destructor and that is the difference between Dispose and FreeMem?

Thanks,

Andrew Haines

The other difference is that dispose() will finalize any reference counted fields, while freemem won't.

Ok so freemem is okay as long as I am careful about the members of the object.

There may be other problems I'm not thinking of right now. I don't understand why you want to use freemem for objects, since the only difference with dispose is that it will result in crashes or memory corruption under certain circumstances.
