这是我测试过的解决方案,结果很好:
LARGE_INTEGER liFreq, liNow;
SYSTEMTIME sstNow;
char szMsg[768];
long lngMicro;
/*Get high performance frequency and counter*/
QueryPerformanceFrequency(&liFreq);
QueryPerformanceCounter(&liNow);
/*Work out elapsed microseconds using frequency*/
liNow.QuadPart *= 1000000;
liNow.QuadPart /= liFreq.QuadPart;
/*Mask out everything >= 1 second */
lngMicro = liNow.QuadPart % 1000000;
/*Get the system date and time*/
GetLocalTime(&sstNow);
/*Build up formatted debug string including sequence number, line number
*date and time stamp including microseconds and message detail*/
sprintf_s(szMsg, sizeof(szMsg)
,"%4d-%02d-%02d %02d:%02d:%02d.%06ld DBG:%-24sL%05uSQ%05uET%16.6f%s%s\n"
,sstNow.wYear, sstNow.wMonth, sstNow.wDay
,sstNow.wHour, sstNow.wMinute, sstNow.wSecond
,lngMicro, cpszClipped, uintLineNo
,suintDbgSeqNo, dblElapsed, sszIndents, cpszFormat);
这并不是全部功能,但希望能为任何人提供足够的信息,让他们了解发生了什么以及它是如何工作的,下面是使用此技术生成的日志文件的一个片段:
