Sous windows et Unix, comment faire en C pour connaitre la place restante ?
en gros simuler le df d'Unix. (je ne connais pas l'équivalent windows)
j'aimerai tester si il reste assez de place dans le dossier (paramètre) avant d'y stocker un fichier dont je connais la taille.
Merci d'avance ;)
C'est une question pour le forum "Développement Windows"Citation:

ben pourquoi ?
je voudrais savoir le faire aussi sous Linux ?
pas de "méthode générique"... ?
on doit bien pouvoir faire ça en C non ? (sans lister tous les fichiers... lol)
Bon, vais poster une demande ds forum Windows :p
PS : j'suis vex je trouve pas la source de df :s
pis j'ai pas trop envie de faire des appels systèmes...
Alors aussi sur le forum "Linux et Développement Linux"Citation:

Pas en C standard en tout cas.Citation:

A moins qu'il y ait une fonction POSIX.1, (voici la liste des 1123 fonctions et macros)Citation:
