Hi i want to execute some system commands from c code.. I know about the execv* family commands but still i dont know how to use them for executing the following thing

tc qdisc change dev $DEV parent 3:20 gred limit 34567 min 39222 max 78644 burst 64 avpkt 1024 bandwidth 6000 DP 1 probability 0.001 prio 1

Any good suggestion how to use the execv command to execute it properly?
Thx

Code:

char *args[] = {
   "qdisc",
   "change",
   "dev",
   "eth4", //"$DEV",
   "parent",
   "3:20",
   "gred",
   "limit",
   "34567",
   "min",
   "39222",
   "max",
   "78644",
   "burst",
   "64",
   "avpkt",
   "1024",
   "bandwidth",
   "6000",
   "DP",
   "1",
   "probability",
   "0.001",
   "prio",
   "1",
   NULL};

   execv("/sbin/tc", args);

hi,
you can use
system e.g.

Code:

system("clear")
