[ns] Trace-queue

[Gerald Jeampierre <jeampier@eikon.e-technik.tu-muenchen.de>]

Dear ns-users,

I try to use two trace-queue commandos:

set tf [open out1.tr w]
$ns trace-queue $n1 $n2 $tf

set tf [open out2.tr w]
$ns trace-queue $n1 $n3 $tf

in my program, but it doesn't seem to work...(my file out2.tr is
empty...).
May someone tell me if/where I'm wrong or tell me how I can extract two
trace-queue from one simulation??? I don't feel like using the huge
all-trace-file just for few links....

Thanks,

Gerald
