Question

Can i output some text to a file using solely boost libraries?

The code i have (official documentation):

#include <ostream>
#include <boost/iostreams/device/file.hpp>
#include <boost/iostreams/stream.hpp>

namespace io = boost::iostreams;

int main()
{
    io::stream_buffer<io::file_sink> buf("log.txt");
    std::ostream                     out(&buf);
    // out writes to log.txt
    out << "abc";
}

Is there another way? (i dont want to use std streams). Thanks in advance.

Answer 1

io::stream_buffer is derived from std::basic_streambuf, so you can use native basic_streambuf public methods, or you can use boost::filesystem streams, but all of such classes are derived from std:: classes.
