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...

atr_analysis

ATR_ANALYSIS(1p)						   User Commands						  ATR_ANALYSIS(1p)

NAME

       ATR_analysis - analyse a smart card ATR

SYNOPSIS

       ATR_analysis [ATRstring]

DESCRIPTION

       ATR_analysis is used to parse the ATR (Answer To Reset) sent by a smart card.

       The command also tries to find the card model using an ATR database stored in a text file smartcard_list.txt.

       The smartcard_list.txt file is searched in ./, /usr/local/pcsc/ and /usr/share/pcsc/ directories.

       Exemple:
	$ ATR_analysis '3B A7 00 40 18 80 65 A2 08 01 01 52'
	ATR: 3B A7 00 40 18 80 65 A2 08 01 01 52
	+ TS = 3B --> Direct Convention
	+ T0 = A7, Y(1): 1010, K: 7 (historical bytes)
	  TB(1) = 00 --> Programming Param P: 0, I: 0
	  TD(1) = 40 --> Y(i+1) = 0100, Protocol T = 0
	-----
	  TC(2) = 18 --> Work waiting time: 960 x 24 x (Fi/F)
	+ Historical bytes: 80 65 A2 08 01 01 52

	Possibly identified card:
	3B A7 00 40 18 80 65 A2 08 01 01 52
	       Gemplus GPK8000

BUGS

       Maybe many bugs since I am not a ISO 7816 expert.
