popen with args?

how can a call a program with command line args?

i checked out popen, but i havnt seen anything about program arguements.

You mean like:

fp = popen ("ping 127.0.0.1", "r");

i was wondering if something like this was possible

popen("ping %s", r, ip_string);

If you look at, and actually read, the man page, popen only takes 2 parameters.
