linux 常用函數

        struct timezone tz;        struct timeval stHandleHistoryRecordFactlyStartTime;        struct timeval stHandleHistoryRecordFactlyEndTime;        gettimeofday(&stHandleHistoryRecordFactlyStartTime,&tz);       dosomething();//處理一些函數的時間        gettimeofday(&stHandleHistoryRecordFactlyEndTime,&tz);       int iHandleHistoryRecordFactlyTime = (stHandleHistoryRecordFactlyEndTime.tv_sec - stHandleHistoryRecordFactlyStartTime.tv_sec)*1000 + (stHandleHistoryRecordFactlyEndTime.tv_usec - stHandleHistoryRecordFactlyStartTime.tv_usec)/1000;

 

    則 iHandleHistoryRecordFactlyTime就是間隔時間
