about packet unique identifier (uid_)

["Luca" <fn214432@flashnet.it>]

Hi,
in Ns "Notes and Documentation", chapter 11 (about Packets), it's written: "
The copy() member function creates a new identical copy of a packet with the
exception of uid_ field, wich is unique".
To me it seem not to be true!!
Here is the source code :

inline Packet* Packet::copy() const
{
 Packet* p = alloc();
 memcpy(p->bits(), bits_, hdrlen_);
 if (datalen_) {
  p->datalen_ = datalen_;
  p->data_ = new unsigned char[datalen_];
  memcpy(p->data_, data_, datalen_);
 }
 return (p);
}

As shown, the copy() function  completely duplicates the bits_ buffer which
contains (in the common header) the uid_.
So I think that duplicated packets share the same uid_ !! ( I mean the uid_
in the common header and not the uid_ member of the Event class used by the
Scheduler).
Can someone tell me if I'm right or wrong?? And if I'm wrong, why?
Another little question: the uid_ member of the Event class is used by the
Scheduler, who is the uid_ in the common header used by?
Please answer, thanks a lot!

Luca
