You can use boost::iostreams::stream.

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

int main() {
    std::string filename("test");
    boost::iostreams::stream<boost::iostreams::file_source> 
file(filename.c_str());
    std::string line;
    while (std::getline(file, line)) { }
}
