i am not a linux programmer so this probably isnt perfect. do you know what pipes are? if not read about them. there is a function in stdio, popen that returns a FILE pointer but for a pipe instead of a file. read about popen then try the following
f = popen("ls", "r");
// here you can use f as you would any normal FILE pointer but it
// contains the output of the ls command
obviously you want to add some error checking in there and replace ls with ifconfig or whatever command you want to execute.
