Re: [Boost-users] [boost::logging] flushing rolling_file

Hi John, hi all

As I don't know how to parameter boost::logging to flush messages in 
rolling files, I modify the code as follow.

My question is :
Is it absolutly necessary to change the code to do that ?

Thanks,
Benjamin

///// rolling_file.hpp ///////

    void recreate_file() {...
                m_cur_size = 0;
     }

    template<class msg_type> void write( const msg_type& msg) {
        convert_dest::write(msg, (*m_out) );

        // flush each time
        m_cur_size += msg.size();
        m_out->flush();
        if ( m_cur_size > m_flags.max_size_bytes()) {
            m_cur_idx = (m_cur_idx + 1) % m_flags.file_count();
            recreate_file();
        }   
    }

    size_t m_cur_size;
