std::ostreambuf_iterator::ostreambuf_iterator
std::ostreambuf_iterator::ostreambuf_iterator
ostreambuf_iterator( streambuf_type* buffer ); | (1) | |
ostreambuf_iterator( ostream_type& stream ); | (2) |
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 |
Exceptions
(none) | (until C++11) |
noexcept specification: noexcept | (since C++11) |
Example
#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'; }
