[linux] Socket operation on non socket
salut tout le monde, j'ai posté mon code dans le forum developpement linux, mais comme il y a eu aucune reponse depuis hier, je suis venu voir les gens d'ici.
voici mon code :

le serveur se lance bel et bien, mais le client me retourne cette erreur, et connect retourne 0 (j'ai lu quelque part que ceci n'est pas un probleme du fait que c'est >0).
une idee la dessus?
merci d'avance.
