新写的c++日志库：log4K

网是开源的c/c++日志库也不少，但用起来总觉得不方便，于是动手写了一个C++日志框架Log4K。

测试代码：

#include "log4k.h"

#pragma comment(lib, "log4k.lib")

static int g_Cnt = ;

void LogTestThread1(LPVOID lpPara)

{

    DEBUG_FUNCTION();

    LOGFMTT(L"----------Function:%s, Line:%d", __FUNCTIONW__, __LINE__);

    LOGFMTD(L"----------Function:%s, Line:%d", __FUNCTIONW__, __LINE__);

    LOGFMTI(L"----------Function:%s, Line:%d", __FUNCTIONW__, __LINE__);

    LOGFMTW(L"----------Function:%s, Line:%d", __FUNCTIONW__, __LINE__);

    LOGFMTE(L"----------Function:%s, Line:%d", __FUNCTIONW__, __LINE__);

    for (int i = ; i < ;)

    {

        LOGFMTT(L"[%d] %s", i++, __FUNCTIONW__);

        //Sleep(10);

    }

}

void LogTestThread2(LPVOID lpPara)

{

    DEBUG_FUNCTION();

    LOGFMTT_A("----------Function:%s, Line:%d", __FUNCTION__, __LINE__);

    LOGFMTD(L"----------Function:%s, Line:%d", __FUNCTIONW__, __LINE__);

    LOGFMTI_A("----------Function:%s, Line:%d", __FUNCTION__, __LINE__);

    LOGFMTW(L"----------Function:%s, Line:%d", __FUNCTIONW__, __LINE__);

    LOGFMTE_A("----------Function:%s, Line:%d", __FUNCTION__, __LINE__);

    for (int i = ; i < ;)

    {

        LOGFMTI(L"[%d] %s", i++, __FUNCTIONW__);

        //Sleep(10);

    }

}

int main()

{

    DEBUG_FUNCTION();

    LOG4K_SET_OUT(Kevin55::OUT_TO_STDOUT_AND_LOG);

    LOGFMTT(L"----------Function:%s, Line:%d", __FUNCTIONW__, __LINE__);

    LOGFMTD(L"----------Function:%s, Line:%d", __FUNCTIONW__, __LINE__);

    LOGFMTI(L"----------Function:%s, Line:%d", __FUNCTIONW__, __LINE__);

    LOGFMTW(L"----------Function:%s, Line:%d", __FUNCTIONW__, __LINE__);

    LOGFMTE(L"----------Function:%s, Line:%d", __FUNCTIONW__, __LINE__);

    LOGFMTT_A("----------Function:%s, Line:%d", __FUNCTION__, __LINE__);

    LOGFMTD_A("----------Function:%s, Line:%d", __FUNCTION__, __LINE__);

    LOGFMTI_A("----------Function:%s, Line:%d", __FUNCTION__, __LINE__);

    LOGFMTW_A("----------Function:%s, Line:%d", __FUNCTION__, __LINE__);

    LOGFMTE_A("----------Function:%s, Line:%d", __FUNCTION__, __LINE__);

    HANDLE hThread[];

    ZeroMemory(hThread, sizeof(HANDLE) * );

    hThread[] = CreateThread(NULL, , (LPTHREAD_START_ROUTINE)LogTestThread1, NULL, , NULL);

    hThread[] = CreateThread(NULL, , (LPTHREAD_START_ROUTINE)LogTestThread2, NULL, , NULL);

    for (int i = ; i < ; i++)

    {

        LOGFMTD(L"[%d]======%s", i, __FUNCTIONW__);

    }

    WaitForMultipleObjects(, hThread, true, INFINITE);

    //LOG4K_SET_OUT(OUT_TO_STDOUT);

    LOGFMTT(L"----------Function:%s, Line:%d", __FUNCTIONW__, __LINE__);

    LOGFMTD(L"----------Function:%s, Line:%d", __FUNCTIONW__, __LINE__);

    LOGFMTI(L"----------Function:%s, Line:%d", __FUNCTIONW__, __LINE__);

    LOGFMTW(L"----------Function:%s, Line:%d", __FUNCTIONW__, __LINE__);

    LOGFMTE(L"----------Function:%s, Line:%d", __FUNCTIONW__, __LINE__);

    return ;

}

使用nmake编译及链接完成后，还有error信息，下面是所有nmake输出：

网上好像有人提交过类似的问题：https://connect.microsoft.com/VisualStudio/feedback/details/808657/vs2013-compiler-fails-on-function-templates-with-c-11-alternate-declaration-syntax，这个问题可能是编译器的一个bug。
