std::ostreambuf_iterator<CharT,Traits>::ostreambuf_iterator

	(1)
ostreambuf_iterator( streambuf_type* buffer ) throw();		(until C++11)
ostreambuf_iterator( streambuf_type* buffer ) noexcept;		(since C++11)
	(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

#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';
}
