You're going to need to first use pipe to generate a pair of pipe ends, fork, connect the stdout of the child process to the input pipe, and exec the command, similar to the way that we currently fork child processes for AGI or MOH mpg123.  It's actually identical to the way that system() works, except that the wait() on the child process isn't executed until later, usually in a signal handler for SIGCHLD.  This ensures that both processes execute concurrently, and the child feeds line-by-line output to the original script, which allows it to react more immediately to the output.
