Se comporte comme le std::basic_streambuf::overflow classe de base, si ce n'est que pour écrire les données de la zone mise à la séquence de caractères associé (dans le fichier), utilise pour la première codecvt::out() de la localisation imprégnée pour convertir les caractères en externe (éventuellement multi-octets) de la représentation, stockée dans un tampon temporaire (attribué aussi grand que nécessaire), puis utilise le fichier I / O pour copier tous les octets entièrement convertis dans le fichier .
Original:
Behaves like the base class std::basic_streambuf::overflow, except that to write the data from the put area to the associated character sequence (to the file), first uses codecvt::out() of the imbued locale to convert the characters into external (possibly multibyte) representation, stored in a temporary buffer (allocated as large as necessary), then uses file I/O to copy all fully-converted bytes into the file.
