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';
