Cette fonction est appellee par operateur>>, get, get_nom ouvrir, fermer, lire, etc.

.. en cas d'echec (lorsque fail() est mis) Elle renvoie 0 s'il y a eu une erreur (passer par error_handle() qui traite en inline le cas ou il n'y a pas d'erreur), et 1 s'il n'y a pas d'erreur. (par commodite de codage des methodes qui l'utilisent, on ecrira "return error_handle(fail());" Elle peut etre configuree pour

renvoyer "0" en cas d'erreur et continuer l'execution du code (cas d'un ancien code qui ne gere pas les exceptions mais teste le drapeau fail() de temps en temps) Dans ce cas les methodes operator>> continuent l'execution du code meme en cas d'echec, le contenu des variables lues est indefini !
faire Process::exit() (cas d'une portion de code dans laquelle on ne veut pas faire de gestion d'erreur du tout et ou on suppose que tout va toujours bien)
lever une exception (permet une gestion rigoureuse des erreurs et une information utilisateur optimale en fonction du contexte)

◆ get() [1/6]

int Entree::get	(	char *	ob,
		std::streamsize	bufsize )

virtual

Lecture d'une chaine dans ostream_ bufsize est la taille du buffer alloue pour ob (y compris.

le caractere 0 final). La chaine contient toujours un 0 meme en cas d'echec. La methode renvoie 1 si la lecture est bonne, 0 sinon. Si le buffer est trop petit, pour l'instant on fait exit() mais par la suite on pourra tester: si strlen(ob)==bufsize-1, alors refaire lire() jusqu'a arriver au bout. Si le lire() suivant renvoie une chaine de longueur nulle, cela signifie que la taille de la chaine etait exactement bufsize-1. Attention: le comportement est different en binaire et en ascii. En binaire, on lit la chaine jusqu'au prochain '\0'. En ascii, on lit la chaine jusqu'au prochain separateur (espace, tab, fin ligne)
