如何使用boost :: iostreams传递到std :: cout [英] How to pipe into std::cout with boost::iostreams

问题描述

我是boost::iostreams的新手，所以这可能微不足道:

I am new to boost::iostreams so this might be trivial:

假设namespace io = boost::iostreams;

这有效

io::filtering_ostream out(std::cout);
out << "some\nstring\n";

这有效

std::string result;
io::filtering_ostream out(io::counter() | io::back_inserter(result));
out << "some\nstring\n";

但是这还不能编译

io::filtering_ostream out(io::counter() | std::cout);
out << "some\nstring\n";

您如何通过管道插入std::cout?
