Now i want to execute sth more difficult and i think i need your help
i want to execute the following
tc -s class show dev eth0
Fork-Exec Or System(3)
I don't think that this is really any different from any other command issued from a C program; if you need to grab the output into a pipe or something you can fork and exec, or if you just need the output to show up on the terminal you could use a call to system(3).
See "man 3 popen".
