~basic_olostream () | |
Output stream that writes data back to a large object.
Use this class exactly as you would any other ostream to write data to a large object. All formatting and streaming operations of std::ostream
are supported. What you'll typically want to use, however, is the olostream alias (which defines a basic_olostream for char
). This is similar to how e.g. std::ofstream
is related to std::basic_ofstream
.
Currently only works for <char, std::char_traits<char>>
.
