  First of all, since you're using spawn rather than fork, I'll assume you're  
using DOS and answer accordingly, although the same techniques apply and the  
essential function is ANSI...

        freopen("FILE", "w", stdout);
        ercode = spawnlp(P_WAIT, "PROG.EXE", "PROG", "ARGS", NULL);
        freopen("CON", "w", stdout);
