CI / O подмножество C + + библиотеки стандартных реализует C-стиле входного потока / вывода. <cstdio> заголовок содержит общие поддержки операции с файлами и расходные материалы функций с узкими и многобайтовых символов входов / выходов, а <cwchar> заголовок предоставляет функции с широким диапазоном входного символа / выходов.

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.

C потоки являются объектами типа std::FILE, которые могут быть доступны только и управляется через указатели типа std::FILE* (Примечание: в то время как это может быть возможным, чтобы создать локальный объект типа std::FILE путем разыменования и копирования действительна FILE*, используя адрес такой копии в Функции ввода / вывода неопределенное поведение). Каждый поток C связан с внешними физического устройства (файл, стандартный входной поток, принтер, последовательный порт, и т.д.).

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).

C потоков могут быть использованы как для неформатированного и форматированный ввод и вывод. Они учетом локали и может выполнять широкий / многобайтовую преобразования по мере необходимости. В отличие от C + + потоков, где каждый поток связан с его собственным языка, все потоки C доступ к тем же объектом языка: одним из наиболее недавно установили с 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.

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