Bonjour,

Je n'ai pas été plus loin que ça, mais déjà il manque un argument:

Code:

sprintf(sd, argv[1]);

Demande à ton compilateur de te donner le maximum de warnings....

Edit: tous tes sprintf sont sur le même modèle.... pourquoi ne pas utiliser strcpy(...)?

Edit 2: mkdir(od, 0777): ça, c'est vraiment sale: utlise les flags fournis par ta librairie.

Si tu as oublié les flags dont parle edgarjacobs, les voici :

Citation:

gcc -Wall -Wextra -Werror -std=c99 -pedantic mes_sources.c

Le code est assez long, donc c'est ardu de trouver des problèmes dans la logique ^^'
(et corriger les problèmes en dehors de la logique sera un gros + déjà ! :) )

Bonjour,

L'utilisation de valgrind aidera beaucoup pour les problèmes de mémoire

Bonjour
Bienvenue dans le monde du "comportement indéterminé". J'ai mis en rouge mes remarques dans ton code mais va te falloir examiner chaque pointeur à la loupe avec tous ces malloc() non vérifiés et ces appels de fonctions où le retour écrase un pointeur déjà alloué. Mais je crois que le principal pb c'est qu'il y a trop de commentaires...

Comme le dit Sve@r il y a trop d'appel de fonctions sans vérification des valeurs d'erreurs qu'elles peuvent retourner.

Un petit conseil pour éviter de faire des erreurs du genre prend l'habitude à chaque fois que tu utilises une fonction de prendre le temps de regarder sont manuel (il y a toujours un moyen de les trouver), cela devrait t'aider grandement et souvent te permettre de mieux comprendre leur fonctionnement et leurs divers comportement. ;)

Elles sont même disponibles en français sur Developpez : http://man.developpez.com/
