调试器用户经常会需要查看在启动调试目标时使用了哪些命令行参数，这个信息是保存在PEB中的，可以通过!peb来获取，这个命令将解析PEB并给出完整的命令行，所有已加载DLL的位置，以及环境变量等.

一样的~~~~，不一样就不正常了！
为什么有三个list:其实三个都一样，顺序不同而已.
LIST_ENTRY InLoadOrderModuleList; //按加载顺序 LIST_ENTRY InMemoryOrderModuleList; //按内存顺序 LIST_ENTRY InInitializationOrderModuleList;//按初始化顺序
_LIST_ENTRY的结构如下：
0:000> dt _LIST_ENTRY ntdll!_LIST_ENTRY +0x000 Flink : Ptr32 _LIST_ENTRY +0x004 Blink : Ptr32 _LIST_ENTRY
按MSDN解释是：
Each item in the list is a pointer to an LDR_DATA_TABLE_ENTRY structure,双向循环链表吧，从一个方向开始，不停的循环，就回到初始位了，就相当于遍历了一次
0:000> dt _LDR_DATA_TABLE_ENTRY ole32!_LDR_DATA_TABLE_ENTRY +0x000 InLoadOrderLinks : _LIST_ENTRY +0x008 InMemoryOrderLinks : _LIST_ENTRY +0x010 InInitializationOrderLinks : _LIST_ENTRY +0x018 DllBase : Ptr32 Void +0x01c EntryPoint : Ptr32 Void +0x020 SizeOfImage : Uint4B +0x024 FullDllName : _UNICODE_STRING +0x02c BaseDllName : _UNICODE_STRING +0x034 Flags : Uint4B +0x038 LoadCount : Uint2B +0x03a TlsIndex : Uint2B +0x03c HashLinks : _LIST_ENTRY +0x03c SectionPointer : Ptr32 Void +0x040 CheckSum : Uint4B +0x044 TimeDateStamp : Uint4B +0x044 LoadedImports : Ptr32 Void +0x048 EntryPointActivationContext : Ptr32 _ACTIVATION_CONTEXT +0x04c PatchInformation : Ptr32 Void +0x050 ForwarderLinks : _LIST_ENTRY +0x058 ServiceTagLinks : _LIST_ENTRY +0x060 StaticLinks : _LIST_ENTRY +0x068 ContextInformation : Ptr32 Void +0x06c OriginalBase : Uint4B +0x070 LoadTime : _LARGE_INTEGER
可以看到头部开始就是个_LIST_ENTRY
我们来做次循环查询吧：
0:000> dt 0x77847880+0x00c _LIST_ENTRY ole32!_LIST_ENTRY [ 0x3126f8 - 0x36bd60 ] +0x000 Flink : 0x003126f8 _LIST_ENTRY [ 0x312788 - 0x7784788c ] +0x004 Blink : 0x0036bd60 _LIST_ENTRY [ 0x7784788c - 0x354a80 ]
对比上面的显示：
+0x00c InLoadOrderModuleList : _LIST_ENTRY [ 0x3126f8 - 0x36bd60 ]
可以看出，windbg这里是在后面括号里显示Flink和Blink，那么我们向着Flink循环吧：

对比!peb的输出：

当然是一样的~~~
下一步是怎么直接得到进程的cmdline：我们注意到PEB0x10处的偏移
+0x010 ProcessParameters : 0x00311b48 _RTL_USER_PROCESS_PARAMETERS
dt一下试试:
