Controlling input and output for files.
_CharT | Type of character stream. |
_Traits | Traits for character type, defaults to char_traits<_CharT>. |
This class supports reading from and writing to named files, using the inherited functions from std::basic_iostream. To control the associated sequence, an instance of std::basic_filebuf is used, which this page refers to as sb
.
