Windows 和 Linux時間函數

做個小記號，前天昨天都在嘗試編譯MPlayer，很遺憾還沒成功，我想讓我小板子跑起視頻的願望還沒實現，今天用到的時間函數先做個記錄吧

 

Windows版本，擷取當前毫秒數，以及如何得到當前年月日時間等，主要用到_ftime, localtime函數，還有一個time()函數則只能得到秒數，沒有毫秒

 

    time_t now;
    struct tm mylocaltime;
    struct _timeb timebuffer;
    struct tm * newtime;
    unsigned short millitm1;

    _ftime( &timebuffer);
    now = timebuffer.time;
    millitm1 = timebuffer.millitm;
    newtime = localtime(&now);
    mylocaltime = *newtime;
    fprintf(log_file(), "[%d-%d-%d %02d:%02d:%02d:%ld",
        mylocaltime.tm_year + 1900, mylocaltime.tm_mon + 1, mylocaltime.tm_mday,
        mylocaltime.tm_hour, mylocaltime.tm_min, mylocaltime.tm_sec, millitm1);

 

 

linux則用下面這兩個函數

 

   gettimeofday(&now, NULL);
    localtime_r(&now.tv_sec, &mylocaltime);

    fprintf( "[%d-%d-%d %02d:%02d:%02d:%ld",
           mylocaltime.tm_year + 1900, mylocaltime.tm_mon + 1, mylocaltime.tm_mday,
        mylocaltime.tm_hour, mylocaltime.tm_min, mylocaltime.tm_sec, now.tv_usec / 1000);
