windows程序崩溃时自动生成dump文件方法

/****************第一步添加createdump.h*********************************

添加一个头文件：createdump.h

/***************第二步*************************************

在main 函数的文件中加入

#include <windows.h>
#include "createdump.h"

LONG WINAPI GPTUnhandledExceptionFilter(PEXCEPTION_POINTERS pExceptionInfo)
{
   CreateMiniDump(pExceptionInfo, L"Exception.dmp");
   exit(pExceptionInfo->ExceptionRecord->ExceptionCode);
   return EXCEPTION_EXECUTE_HANDLER; // 程序停止运行
}

/***************第三步*************************************

在main函数中加入：

SetUnhandledExceptionFilter(GPTUnhandledExceptionFilter);
