I have something like this:
PStruct = ^Struct;
Struct = record
num : integer;
end;
I have a unit to handle that structure ( is a bit more complicated, but
is a good example), in this unit I have a procedure that deletes (
disposes ) the pointer. How can I know if a pointer are created or not?,
I mean, I don't wont to try to delete something that has not been
created yet, but I don't know how to do it, if that is possible.
Thanks a lot.
Zaka.
