How to use an external library to output the internal logs of this library ？

[xinruoshinian]

After I encapsulated this library into a dynamic library, I have a logbase on my side, and I want it to be able to call back an interface to provide me with external logbase output, what should I do? Can you give me an example, I didn't find it in the code, thanks!

I see this way of inheriting the subclass rewrite in the code, but then I don't know what to do, can you tell me how to write it?

`class MyCustomLogHandler : public NPT_LogHandler
{
public:
MyCustomLogHandler() {}

// 重写 Log 方法
virtual void Log(const NPT_LogRecord& record) override
{
    //将日志输出到文件或者其他地方
    std::ofstream log_file("custom_log.txt", std::ios::app);
    if (log_file.is_open()) {
        log_file << "[" << record.m_LoggerName << "] "
            << record.m_Message << std::endl;
    }
    // 也可以输出到控制台
    std::cout << "[" << record.m_LoggerName << "] "
        << record.m_Message << std::endl;

    return;
}
