Le niveau de soutien pour les modes autres que std::ios_base::in ouverts et std::ios_base::out varie selon les implémentations. C + 11 spécifie explicitement le soutien à std::ios_base::ate dans
str() et en ce constructeur, mais std::ios_base::app, std::ios_base::trunc et std::ios_base::binary ont des effets différents sur différentes implémentations .Original:
The level of support for the open modes other than std::ios_base::in and std::ios_base::out varies among implementations. C++11 explicitly specifies the support for std::ios_base::ate in
str() and in this constructor, but std::ios_base::app, std::ios_base::trunc, and std::ios_base::binary have different effects on different implementations.The text has been machine-translated via Google Translate.
