如何解决错误 # args: 应该是“_o3 self class proc file optx opty”
错误的#args：应该是“o3 self class proc file optx opty” （模拟器namtrace-all-wireless line 1） 从内部调用 “$ns namtrace-all-wireless $namtracefd” （文件“test1.tcl”第26行）

解决方法
错误的 # args: 应该是 ... optx opty
几个错别字之一：原来的第 26 行应该是 $ns_ namtrace-all-wireless $namtracefd $opt(x) $opt(y)
