hi, I'm simulating an ad hoc net, I got the following error message when executing my tcl file:
num_nodes is set 8 INITIALIZE THE LIST xListHead wrong # args: should be "_o3 self class proc node agent" (Simulator attach-agent line 1) invoked from within "$ns attach-agent $n(1) $tcp (file "xxx.tcl" line 144) here is some of the code: set tcp [new Agent/TCP/Newreno] $tcp set class_ 2 $tcp set window_ 2000 $ns attach-agent $n(1) $tcp #line 144 can anyone help me to fix this error or at least to understand the cause of it thanks
