看了不少关于_LDR_MODULE定义的贴,
[_LDR_MODULE -------->>> LDR_DATA_TABLE_ENTRY]
自己在实际中的发现,却与这个定义有点出入。我的系统信息如下:
OS 名称: Microsoft Windows XP Professional
OS 版本: 5.1.2600 Service Pack 2 Build 2600
======================================
typedef struct _LDR_DATA_TABLE_ENTRY
{
LIST_ENTRY InLoadOrderLinks;
LIST_ENTRY InMemoryOrderLinks;
LIST_ENTRY InInitializationOrderLinks;
PVOID DllBase;
PVOID EntryPoint;
ULONG SizeOfImage;
UNICODE_STRING FullDllName;
UNICODE_STRING BaseDllName;
ULONG Flags;
WORD LoadCount;
WORD TlsIndex;
union
{
LIST_ENTRY HashLinks;
struct
{
PVOID SectionPointer;
ULONG CheckSum;
};
};
union
{
ULONG TimeDateStamp;
PVOID LoadedImports;
};
_ACTIVATION_CONTEXT * EntryPointActivationContext;
PVOID PatchInformation;
LIST_ENTRY ForwarderLinks;
LIST_ENTRY ServiceTagLinks;
LIST_ENTRY StaticLinks;
} LDR_DATA_TABLE_ENTRY, *PLDR_DATA_TABLE_ENTRY;

============================================
希望大家能解释一下,上面的两处 “?????” 到底是何作用,并附上一份LDR_DATA_TABLE_ENTRY的正式定义,因为发现好多LDR_DATA_TABLE_ENTRY与自己的发现有些出入,所以不由的怀疑网上的那些定义。
如果有什么不对的地方,欢迎大家指正.
