std::ostreambuf_iterator

Member functions

ostreambuf_iterator::ostreambuf_iterator

ostreambuf_iterator::operator=

ostreambuf_iterator::operator*

ostreambuf_iterator::operator++ ostreambuf_iterator::operator++(int)

ostreambuf_iterator::failed

 

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

noexcept specification:  

noexcept

  (since C++11)

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';
}
