Le sous-ensemble CI / O de la bibliothèque standard C + + met en œuvre des flux d'entrée de style C / opérations de sortie. L'en-tête
<cstdio> fournit un soutien générique opération de fichier et des fonctions étroites avec les fournitures et multi-octets caractères d'entrée / de sortie des capacités, et l'en-tête <cwchar> fournit des fonctions d'entrée de caractères larges / capacités de sortie . Original:
The C I/O subset of the C++ standard library implements C-style stream input/output operations. The
<cstdio> header provides generic file operation support and supplies functions with narrow and multibyte character input/output capabilities, and the <cwchar> header provides functions with wide character input/output capabilities. The text has been machine-translated via Google Translate.

Flux de C sont des objets de std::FILE type qui ne peut être accédé et manipulé par un pointeur de type std::FILE* (Remarque: bien qu'il soit possible de créer un objet local de type de std::FILE par le déréférencement et la copie d'un FILE* valide, en utilisant l'adresse de cette copie dans les fonctions d'E / S est un comportement indéfini). Chaque flux de C est associé à un dispositif physique externe (fichiers, le flux d'entrée standard, une imprimante, un port série, etc) .
Original:
C streams are objects of type std::FILE that can only be accessed and manipulated through pointers of type std::FILE* (Note: while it may be possible to create a local object of type std::FILE by dereferencing and copying a valid FILE*, using the address of such copy in the I/O functions is undefined behavior). Each C stream is associated with an external physical device (file, standard input stream, printer, serial port, etc).

Flux de C peut être utilisé à la fois pour l'entrée non formaté et mis en forme et de sortie. Ils sont locale-sensible et peut effectuer de larges / multi-octets conversions nécessaires. Contrairement à C + + ruisseaux, où chaque flux est associé à son propre locale, tous les flux de C accéder à l'objet même lieu: le plus récemment installé avec std::setlocale .
Original:
C streams can be used for both unformatted and formatted input and output. They are locale-sensitive and may perform wide/multibyte conversions as necessary. Unlike C++ streams, where each stream is associated with its own locale, all C streams access the same locale object: the one most recently installed with std::setlocale.

Outre les informations spécifiques au système nécessaire pour accéder à l'appareil (par exemple un descripteur de fichier POSIX), chaque objet de flux C détient les suivantes:

Besides the system-specific information necessary to access the device (e.g. a POSIX file descriptor), each C stream object holds the following:
