redirection stdin

Bonjour,
Mon application en C sous linux tourne en redirigeant stdin vers un fichier.
Exemple; $appli1 <file1.
[Cette appli s'arrête donc régulièrement sur un scanf();]
PB: Je voudrais temporairement redonner la main au user sur le clavier.
Alors je pensais ajouter system("appli2"); dans appli1.
Dans son main() , appli2() fait seulement un scanf(); puis un exit().
Mais lorsque appli1 reprend la main, stdin reste assigné au clavier et
non plus à file1. Or je voudrais qu'il reste assigné à file1!!!
Merci d'avance pour votre réponse...
