    Lit count caractères à partir de la séquence d'entrée et les stocke dans un tableau de caractères pointée par s. Les caractères sont lus comme par des appels répétés à sbumpc(). Autrement dit, si moins de caractères count sont immédiatement disponibles, la fonction appelle uflow() de fournir plus jusqu'à ce que traits::eof() est retourné .
    Original:
    Reads count characters from the input sequence and stores them into a character array pointed to by s. The characters are read as if by repeated calls to sbumpc(). That is, if less than count characters are immediately available, the function calls uflow() to provide more until traits::eof() is returned.
