The class std::basic_ios provides facilities for interfacing with objects that have std::basic_streambuf interface. Several std::basic_ios objects can refer to one actual std::basic_streambuf object. Character type dependent formatting flags and error state is stored in std::basic_ios class.
Two specializations for common character types are also provided:
| Type | Definition |
ios
|
basic_ios<char> |
wios
|
basic_ios<wchar_t> |
