重新修訂自用的文件型日志WIN32 C++類

        對于日志 , 一般在工業24小時執行的程序很多見, 通常的用就是法記錄文本信息.。這次提供的C++類命名為CxLog, 提供文本記錄， 多參數格式化文本紀錄， 二進制數據參照常見16進制編輯器紀錄，對常見編譯器的異常提供便捷的記錄接口。本次提供的類支持多線程，本身也是依賴守護線程執行，也采用了簡單的單件模式，一個程序只會有一個實例，且不需要用戶定義。同時支持UNICODE，支持常見的編譯器,記錄文件時同時會向控制臺輸出，也會向調試窗口輸出， 主要目的就是為了方便，其實程序難度很低，高手莫要見笑。

本文末提供源代碼

文本紀錄： LOG(text);
多參數格式化文本紀錄：
     GNU C++ ：LOGN(format, p1, p2...);
     VC6等不支持多參數宏采用LOG1(format, p1);  LOG2(format, p1, p2); .....
CException: LOGE(e);
_com_error: LOGE(e);
std::exception: LOGE(e);

日志內容：
2008-04-10 15:05:26.469 Exception BaseTestLog.cpp(func, 44): test of c ++ exception.

  
二進制數據: LOG_BIN(pData, uDataSize);
日志內容：
2008-04-10 15:05:26.469 Exception BaseTestLog.cpp(func, 44):
00000060: 60 61 62 63 64 65 66 67 68 69 6A 6B 6C 6D 6E 6F `abcdefghijklmno
對于ASCII的控制字符默認替換成_T('.')，你可以定義宏CX_LOG_REPLACE_ASCII來改變他，也可以定義宏CX_LOG_REPLACE_CONTROL選擇是否替換

總的來說功能也就是記錄文件名、函數名、行號、內容，并提供對常見異常自動擴展，
你可以通過定義宏來改變日志文件名
 比如你定義
#define CX_LOG_FILE_NAME  _T("d:\mylog.log")
日志就會記錄在該文件中
系統默認記錄在.\log下，文件名為程序啟動當天日期
提供按一定時間記錄的功能
通過宏CX_LOG_BY_DAY、CX_LOG_BY_WEEK、CX_LOG_BY_MONTH、CX_LOG_BY_YEAR
改變記錄的文件名




初步遺留問題：
1 聽說VC2005支持多參數宏 沒有安裝測試
2 __FUNCTION__ 的UNICODE擴展在GCC中沒有成功但是__FILE__成功了，我都有點糊涂了 ，所以UNICODE下不支持__FUNCTION__

#define WIDEN2(x) L ## x
#define WIDEN(x) WIDEN2(x)

#define __WFILE__ WIDEN(__FILE__)
#define __WFUNCTION__ WIDEN(__FUNCTION__)//GCC失敗

3 對于不支持多參數宏的采用LOG1~9的擴展宏支持，盡管很難看，暫時我也不會了
4 只支持WIN32 希望有時間考慮開發移植

以下是一個測試用例， 在VC6(sp6)、VC2003、BCB6、GCC3.4.4、GCC4.4.1、Intel C++9下分別在UNICODE和非UNICODE下編譯通過
