[ns] error in the code

[neeraj gupta]

hi all

 i am using the aodv protocol in my scenario. i made certain updation to print the routing table as foolows

Add following code to aodv.h after void rt_down(aodv_rt_entry *rt); 
void rt_print(nsaddr_t node_id); 
Add following code to aodv.cc after  void  AODV:: rt_down (aodv_rt_entry *rt)  {  ... } 
void AODV::rt_print(nsaddr_t node_id) {
FILE *out_file;
char nowfile[50] = "rtable.txt";
out_file = fopen(nowfile, "a");
aodv_rt_entry *rt;

fprintf(out_file, "=================================");

for (rt=rtable.head(); rt; rt = rt->rt_lin.le_next) {
  fprintf(out_file, "NODE: %i\t %.4lf\t%i\t%i\t%i\t%i\t%.4lf\t%d\n", 
  node_id, CURRENT_TIME, rt->rt_dst, rt->rt_nexthop, rt->rt_hops,
  rt->rt_seqno, rt->rt_expire, rt->rt_flags);
}

fclose(out_file);
} 
The function (rt_print) can be used anywhere in AODV. For example, I am using the function when original source node receives route reply message (RREP). 
void AODV:: recvReply(Packet *p) {
 ... 
 if (ih->daddr() == index) { 
   rt_print(index) ; 
   ... 
} 

after ame i got following error rt->rt_lin.le_next not a valid field. can anybody help me to solve the problem. i am using the ns-2.30
