[boost] Cannot access structure elements using iterator to list containing shared_ptr<struct>

13 Jun 2012

      ...
Hi,
...
I would like to have a list(STL) of shared_ptr. The shared_ptr
would hold the pointer to the structure "packet_holder"
.
struct packet {
...
int c;
       union{
            struct pkt_header header;
            struct ip_header ip_hd;
       }type;
}packet_holder;
...
list<boost::shared_ptr<packet_holder> > pkt_list;

...
boost::shared_ptr<packet_holder> pkt(new packet_holder);
 pkt_list.push_pack(pkt);

...
Having defined this, I would like to use iterator to iterate
through the list.
  list<boost::shared_ptr<packet_holder> >::iterator it;
  for(it = list.begin();it != list.end();it++)
         But I am not able to access the inner details of the struct
"packet_holder" using the iterator.
         it->type.header is not accessible.
Can anyone please suggest me where exactly I might be wrong.
