Re: How to call system command

There is not enough info - how do you need to launch the command, from where ??
etc.. do you need the output?? do you need to read the output, do you want it
to block, etc..

1) you can use system("ipchains blah blah&");
2) you can fork a processes
3) you can use pipes :

FILE *pipe 
pipe = popen("ipchains blah blah","r");
that way you can read the output
