我正在尝试创建一个多线程的Boost logger文件。 那可以做以下事情：

1. 写信给目录。
2. 可以在午夜或rache最大文件大小时旋转文件。
3. 需要检查是否有足够的空间将文件刻录到光盘上。
4. 最多可以创建10个日志文件。

我使用的增强版本是1.65.1。

问题是：

1. 提高了具有相同内容示例的2个文件箱： BioEngine_17145_Mon_Nov_11_15_32_40_2019和BioEngine_11_11_2019_15_32_40_0.log
2. 没有一个文件在我需要的目标目录中创建。文件中包含要在哪里运行的文件。
3. 最大文件数不起作用，我分配的文件数超过10个。

我找不到我在做什么。 感谢您提供以下帮助代码。

在将任何日志写入文件之前，从Init函数调用记录器Init函数。

 void LoggerInit(string& log_dir)

        boost::log::keywords::max_files = 10                       /*< maximum number of stored files >*/
    ));

    sink->set_formatter(
        expr::stream
        << "[" << boost::log::expressions::attr<boost::log::process_id>("ProcessID")
        << "][" << boost::log::expressions::attr<boost::log::thread_id>("ThreadID")

        << expr::smessage
    );


    sink->locked_backend()->scan_for_files(boost::log::sinks::file::scan_method::scan_matching,true);

    logging::core::get()->add_sink(sink);
