[ns] bug in mobilenode.cc ?

["Wings" <wings@cis.nctu.edu.tw>]

Dear ns-users,

In mobilenode.cc : (ns-version2.1b8)

Line2 and Line28 have the same if-statement (strcmp(argv[1], "addif") ),why?
Factually, Line28 have never run.
But Line28 seems to add WirelessPhy.
I don't have any idea about this. Could anyone help me to know why?


At MobileNode::command
