MiniDumpWriteDump函数生成dmp文件

一：概述

v2008及以上版本都可以用。 包含CreateDump.h，CreateDump.cpp文件，main()测试例子。

二： CreateDump.h

#pragma once
#include <string>
#include <windows.h>
using namespace std;
class CCreateDump
{
public:CCreateDump();~CCreateDump(void);static CCreateDump* Instance();static long __stdcall UnhandleExceptionFilter(_EXCEPTION_POINTERS* ExceptionInfo);//声明Dump文件，异常时会自动生成。会自动加入.dmp文件名后缀void DeclarDumpFile();
private:static WCHAR    strDumpFile[MAX_PATH];static CCreateDump* __instance;
};

三：CreateDump.cpp

#include "stdafx.h"
#include "CreateDump.h"
#include <DbgHelp.h>
#pragma comment(lib,  "dbghelp.lib")CCreateDump* CCreateDump::__instance = NULL;
WCHAR  CCreateDump::strDumpFile[MAX_PATH] = { 0 };CCreateDump::CCreateDump()
{
}CCreateDump::~CCreateDump(void)
{}long  CCreateDump::UnhandleExceptionFilter(_EXCEPTION_POINTERS* ExceptionInfo)
{HANDLE hFile = CreateFile(strDumpFile, GENERIC_WRITE, FILE_SHARE_WRITE, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);if (hFile != INVALID_HANDLE_VALUE){MINIDUMP_EXCEPTION_INFORMATION   ExInfo;ExInfo.ThreadId = ::GetCurrentThreadId();ExInfo.ExceptionPointers = ExceptionInfo;ExInfo.ClientPointers = FALSE;//   write   the   dumpBOOL   bOK = MiniDumpWriteDump(GetCurrentProcess(), GetCurrentProcessId(), hFile, MiniDumpNormal, &ExInfo, NULL, NULL);CloseHandle(hFile);if (!bOK){DWORD dw = GetLastError();//写dump文件出错处理,异常交给windows处理return EXCEPTION_CONTINUE_SEARCH;}else{    //在异常处结束return EXCEPTION_EXECUTE_HANDLER;}}else{return EXCEPTION_CONTINUE_SEARCH;}
}void CCreateDump::DeclarDumpFile()
{SYSTEMTIME syt;GetLocalTime(&syt);char c[MAX_PATH];::swprintf_s(strDumpFile, _countof(strDumpFile) - 1, L"%04d-%02d-%02d_%02d%02d%02d.dmp", syt.wYear, syt.wMonth, syt.wDay, syt.wHour, syt.wMinute, syt.wSecond);SetUnhandledExceptionFilter(UnhandleExceptionFilter);
}CCreateDump* CCreateDump::Instance()
{if (__instance == NULL){__instance = new CCreateDump;}return __instance;
}

四：main测试

int main()
{CCreateDump::Instance()->DeclarDumpFile();int ag=0;int bg=2;int cg =bg/0;std::cout<<cg<<std::endl;return 0;
}

五：winDbg分析

1) 设置.dmp、.pdb文件所在路径
在以下两个地方设置路径
file->symbol search path
file->source search path

2）分析.pdb
file->open crash
选择 .dmp文件
命令窗口输入： !analyze -v
