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 = 0;
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 = 0; i < 10;)
    {
        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 = 0; i < 10;)
    {
        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[2];
    ZeroMemory(hThread, sizeof(HANDLE) * 2);

    hThread[0] = CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)LogTestThread1, NULL, 0, NULL);
    hThread[1] = CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)LogTestThread2, NULL, 0, NULL);


    for (int i = 0; i < 100; i++)
    {
        LOGFMTD(L"[%d]======%s", i, __FUNCTIONW__);
    }

    WaitForMultipleObjects(2, 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 0;
}

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。
