Defined in header <experimental/iterator>
template <class charT, class traits, class DelimT> std::experimental::ostream_joiner<std::decay_t<DelimT>, charT, traits>     make_ostream_joiner(std::basic_ostream<charT, traits>& os, DelimT&& delimiter);		(library fundamentals TS v2)

Creates an ostream_joiner object, deducing the template arguments from the types of the function arguments.

Parameters

os	-	the basic_ostream object that the iterator is to be associated to
delimiter	-	the delimiter

Return value

A ostream_joiner object, created as if by std::experimental::ostream_joiner<std::decay_t<DelimT>, charT, traits>(os, std::forward<DelimT>(delimiter)).

Example

Run this code

#include <experimental/iterator>
#include <iostream>
#include <vector>
 
int main() {
    std::vector<int> x{1, 2, 3, 4};
    std::copy(x.begin(), x.end(),
              std::experimental::make_ostream_joiner(std::cout, ", "));
}

Output:

1, 2, 3, 4
