windows下生成dumpfile程序崩溃的问题(WriteProcessMemory)

之前在win xp和win7没有问题，用了win10就出问题了.

解决办法:VirtualProtect函数使用VirtualProtectEx代替即可！

所有代码如下:

#ifndef __DUMP_H__
#define __DUMP_H__
#include <stdlib.h>
#include <stdio.h>
#include <ostream>
#ifdef _MSC_VER
#include <windows.h>
#include <DbgHelp.h>
#pragma comment(lib, "dbghelp.lib")

#ifndef _M_IX86  
#error "The following code only works for x86!"  
#endif  

inline BOOL IsDataSectionNeeded(const WCHAR* pModuleName)
{
	if (pModuleName == 0)
	{
		return FALSE;
	}

	WCHAR szFileName[_MAX_FNAME] = L"";
	_wsplitpath_s(pModuleName, NULL, 0, NULL, 0, szFileName, _MAX_FNAME, NULL, 0);

	if (_wcsicmp(szFileName, L"ntdll") == 0)
		return TRUE;

	return FALSE;
}

inline BOOL CALLBACK MiniDumpCallback(PVOID                            pParam,
	const PMINIDUMP_CALLBACK_INPUT   pInput,
	PMINIDUMP_CALLBACK_OUTPUT        pOutput)
{
	if (pInput == 0 || pOutput == 0)
		return FALSE;

	switch (pInput->CallbackType)
	{
	case ModuleCallback:
		if (pOutput->ModuleWriteFlags & ModuleWriteDataSeg)
			if (!IsDataSectionNeeded(pInput->Module.FullPath))
				pOutput->ModuleWriteFlags &= (~ModuleWriteDataSeg);
	case IncludeModuleCallback:
	case IncludeThreadCallback:
	case ThreadCallback:
	case ThreadExCallback:
		return TRUE;
	default:;
	}

	return FALSE;
}

		MiniDumpWriteDump(GetCurrentProcess(), GetCurrentProcessId(),
			hFile, mdt, (pep != 0) ? &mdei : 0, 0, &mci);

		//MiniDumpWriteDump(GetCurrentProcess(), GetCurrentProcessId(), hFile, MiniDumpNormal, (pep != 0) ? &mdei : 0, NULL, &mci);  //普通dump,小

		CloseHandle(hFile);
	}
}
