El nivel de soporte para los modos que no sean abiertas y std::ios_base::in std::ios_base::out varía entre implementaciones. C + 11 especifica explícitamente el apoyo a std::ios_base::ate en str() y en este constructor, pero std::ios_base::app, std::ios_base::trunc y std::ios_base::binary tener efectos diferentes en las distintas aplicaciones .
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.
