libusb_set_log_cb：日志中的垃圾邮件

分类：编程问答

如何解决libusb_set_log_cb：日志中的垃圾邮件

在libusb 1.0.23中添加了 libusb_set_log_cb 函数。我在代码中使用此功能进行记录。我有libusb_log_cb函数：

// In this function I am checking the libusb_log_level then call my log function
// that takes the my logger class,my enum with the log levels and str for logging.
// My log func logs the argument "str" in the file "libusbLogs.log" with the MY_LEVELS level.
void libusbLog(libusb_context* ctx,enum libusb_log_level level,const char* str)
{
    switch (level)
    {
    case LIBUSB_LOG_LEVEL_ERROR:    myFuncForLog(myLogger,MY_LEVELS::LOG_ERROR,"[ctx: " << ctx << "]: " << str); 
        break;
    case LIBUSB_LOG_LEVEL_WARNING:  myFuncForLog(myLogger,MY_LEVELS::LOG_WARNING,"[ctx: " << ctx << "]: " << str);
        break;
    case LIBUSB_LOG_LEVEL_INFO:     myFuncForLog(myLogger,MY_LEVELS::LOG_INFO,"[ctx: " << ctx << "]: " << str);
        break;
    case LIBUSB_LOG_LEVEL_DEBUG:    myFuncForLog(myLogger,MY_LEVELS::LOG_DEBUG,"[ctx: " << ctx << "]: " << str);
        break;
    }
}

这可以正常工作，但是在我的 .log 文件中，我有很多调试消息。一分钟后，我的文件大小增加了10MB。

这是我的 .log 文件的一小部分

我尝试每n次记录一次。但这是不正确的，因为我丢失了一些日志消息
