Salut à tous
Je travaille avec VisualC++ 6.0 sous winNT
J'essaye de lire le port série, mais je n'arrive pas à lire son contenu en une seul fois.
Je pense que l'ideal serait de detecter le dernier caractere du fichier afin de stopper la lecture, mais ma variable de stockage est de type void* est donc je n'arrive pas à l'utiliser..
