[ns] AODV - writing into trace file

[Robin Pomplun]

Hi altogether,

i have a "minor" problem which evolves to a bigger problem for me.
I need to write a line into the AODV trace file, when a node sends a 
data packet. The line should include the source id, the destination id 
and the "pathlength" (meaning the number of hops between source and 
destination).
Then I had a look where AODV writes something into the trace file; I 
only found aodv_logs.*. But where does AODV writes  a line into the 
trace when a node sends, receives and forwards a packet? Did I overlook 
something? I suppose so, but where?

Thanks in advance for any help
