Dear friends:
I wrote a new MAC protocol named ATMAC,there are two files: atmac.h and
atmac.cc.I want to know the queue length from the MAC layer,so in atmac.h I
added some code: Queue *ifq_; inline Queue *ifq() {return ifq_;}
In atmac.cc, I modified the command function:
int ATMAC::command(int argc, const char*const* argv)
{
if (argc == 3) {
if (strcmp(argv[1], "log-target") == 0) {
logtarget_ = (NsObject*) TclObject::lookup(argv[2]);
if(logtarget_ == 0)
return TCL_ERROR;
return TCL_OK;
} else if(strcmp(argv[1], "ifq") == 0) {
ifq_ = (Queue*)TclObject::lookup(argv[2]);
if (ifq_ == 0)
return TCL_ERROR;
return TCL_OK;
}
}
return Mac::command(argc, argv);
}
Then in atmac.cc I use "ifq()->length" to get the queue length from the MAC
layer.However, when I run the tcl script, I got "segmentation fault".
Schould I use the command "ifq" in the tcl script? And how?
Please help me! Any suggestions will be appreciated! Thanks
Regards
David
