std::ostrea...buf_iterator(3) C++ Standard Libarystd::ostrea...buf_iterator(3) NAME std::ostreambuf_iterator::ostreambuf_iterator - std::ostreambuf_itera- tor::ostreambuf_iterator Synopsis ostreambuf_iterator( streambuf_type* buffer ) (until C++11) throw(); ostreambuf_iterator( streambuf_type* buffer ) (since C++11) noexcept; (1) ostreambuf_iterator( ostream_type& stream ) (until C++11) throw(); (2) ostreambuf_iterator( ostream_type& stream ) (since C++11) noexcept; 1) Constructs the iterator with the private streambuf_type* member set to buffer and the failed() flag set to false. The behavior is undefined if buffer is a null pointer. 2) Same as ostreambuf_iterator(stream.rdbuf()). Parameters stream - the output stream whose rdbuf() will be accessed by this iterator buffer - the output stream buffer to be accessed by this iterator Example // Run this code #include <iostream> #include <fstream> #include <iterator> int main() { std::basic_filebuf<char> f; f.open("test.txt", std::ios::out); std::ostreambuf_iterator<char> out1(&f); std::ostreambuf_iterator<wchar_t> out2(std::wcout); *out1 = 'a'; *out2 = L'a'; } Defect reports The following behavior-changing defect reports were applied retroac- tively to previously published C++ standards. DR Applied to Behavior as published Correct behavior default constructor was provided as C++20 re- moved along with the P2325R3 C++20 iterators re- quirement must be default_initializable http://cppreference.com 2022.07.31 std::ostrea...buf_iterator(3)
