(1) | ||

ostreambuf_iterator( streambuf_type* buffer ) noexcept; |

(2) | ||
ostreambuf_iterator( ostream_type& stream ) throw(); |
(until C++11) | |
ostreambuf_iterator( ostream_type& stream ) noexcept; |
(since C++11) | |
1) Constructs the iterator with the private streambuf_type* member set to
buffer
and the failed() bit 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'; }
