dump java崩溃自动 不生成_一个宏命令，就可以程序崩溃时生成dump文件

在主程序初始化时加入

DeclareDumpFile();

创建头文件DumpFile.h, 将下列代码放进文件中

#pragma once

#include

#include < Dbghelp.h>

#include

#include

using namespace std;

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

namespace NSDumpFile

{

// Dump信息

//

dumpInfo.ExceptionPointers = pException;

dumpInfo.ThreadId = GetCurrentThreadId();

dumpInfo.ClientPointers = TRUE;

// 写入Dump文件内容

//

MiniDumpWriteDump(GetCurrentProcess(), GetCurrentProcessId(), hDumpFile, MiniDumpNormal, &dumpInfo, NULL, NULL);

CloseHandle(hDumpFile);

}

}

{
