探测Windows2K/XP/2003本机系统信息
作者：TOo2y
Native API乃Windows用户模式中为上层Win32 API提供接口的本机系统服务。平常我们总是调用MS为我们提供的公用的Win32 API函数来实现来实现我们系统的功能。（PS：前不久，偶写了一个Windows任务管理器，支持对桌面，进程/线程，系统性能，磁盘，环境变量，事件日志，网络，设备驱动，Win32服务，共享，用户，系统及关机等信息的探测和控制，完全基于Win32 API，大家可以到我们的主页下载）。今天我们要谈的是如何通过本机系统服务(Native API）来探测本机系统信息。当然，微软没有为我们提供关于本机系统服务的文档(Undocumented)，也就是不会为对它的使用提供任何的保证，所以我们不提倡使用Native API来开发软件。不过在特殊情况下，本机系统服务却为我们提供了通向“秘密”的捷径。本文提到的信息仅在Windows2000/XP/2003上测试过。
今天，我们主要讨论的是一个函数NtQuerySystemInformation(ZwQuerySystemInformation)。当然，你不要小看这么一个函数，它却为我们提供了丰富的系统信息，同时还包括对某些信息的控制和设置。以下是这个函数的原型：
typedef NTSTATUS (__stdcall *NTQUERYSYSTEMINFORMATION) (IN SYSTEM_INFORMATION_CLASS SystemInformationClass, IN OUT PVOID SystemInformation, IN ULONG SystemInformationLength, OUT PULONG ReturnLength OPTIONAL);NTQUERYSYSTEMINFORMATION NtQuerySystemInformation;从中可以看到，SystemInformationClass是一个类型信息，它大概提供了50余种信息，也就是我们可以通过这个函数对大约50多种的系统信息进行探测或设置。SystemInformation是一个LPVOID型的指针，它为我们提供需要获得的信息，或是我们需要设置的系统信息。SystemInformationLength是SystemInformation的长度，它根据探测的信息类型来决定。至于ReturnLength则是系统返回的需要的长度，通常可以设置为空指针(NULL)。
首先，我们来看看大家比较熟悉的系统进程/线程相关的信息。这个题目在网上已经讨论了N多年了，所以我就不在老生常谈了，呵呵。那么就提出这个结构类型的定义：
typedef struct _SYSTEM_PROCESSES{ULONG NextEntryDelta; //构成结构序列的偏移量；ULONG ThreadCount; //线程数目；ULONG Reserved1[6]; LARGE_INTEGER CreateTime; //创建时间；LARGE_INTEGER UserTime; //用户模式(Ring 3)的CPU时间；LARGE_INTEGER KernelTime; //内核模式(Ring 0)的CPU时间；UNICODE_STRING ProcessName; //进程名称；KPRIORITY BasePriority; //进程优先权；ULONG ProcessId; //进程标识符；ULONG InheritedFromProcessId; //父进程的标识符；ULONG HandleCount; //句柄数目；ULONG Reserved2[2];VM_COUNTERS VmCounters; //虚拟存储器的结构，见下；IO_COUNTERS IoCounters; //IO计数结构，见下；SYSTEM_THREADS Threads[1]; //进程相关线程的结构数组，见下；}SYSTEM_PROCESSES,*PSYSTEM_PROCESSES;
typedef struct _SYSTEM_THREADS{LARGE_INTEGER KernelTime; //CPU内核模式使用时间；LARGE_INTEGER UserTime; //CPU用户模式使用时间；LARGE_INTEGER CreateTime; //线程创建时间；ULONG WaitTime; //等待时间；PVOID StartAddress; //线程开始的虚拟地址；CLIENT_ID ClientId; //线程标识符；KPRIORITY Priority; //线程优先级；KPRIORITY BasePriority; //基本优先级；ULONG ContextSwitchCount; //环境切换数目；THREAD_STATE State; //当前状态；KWAIT_REASON WaitReason; //等待原因；}SYSTEM_THREADS,*PSYSTEM_THREADS;
typedef struct _VM_COUNTERS{ULONG PeakVirtualSize; //虚拟存储峰值大小；ULONG VirtualSize; //虚拟存储大小；ULONG PageFaultCount; //页故障数目；ULONG PeakWorkingSetSize; //工作集峰值大小；ULONG WorkingSetSize; //工作集大小；ULONG QuotaPeakPagedPoolUsage; //分页池使用配额峰值；ULONG QuotaPagedPoolUsage; //分页池使用配额；ULONG QuotaPeakNonPagedPoolUsage; //非分页池使用配额峰值；ULONG QuotaNonPagedPoolUsage; //非分页池使用配额；ULONG PagefileUsage; //页文件使用情况；ULONG PeakPagefileUsage; //页文件使用峰值；}VM_COUNTERS,*PVM_COUNTERS;typedef struct _IO_COUNTERS{LARGE_INTEGER ReadOperationCount; //I/O读操作数目；LARGE_INTEGER WriteOperationCount; //I/O写操作数目；LARGE_INTEGER OtherOperationCount; //I/O其他操作数目；LARGE_INTEGER ReadTransferCount; //I/O读数据数目；LARGE_INTEGER WriteTransferCount; //I/O写数据数目；LARGE_INTEGER OtherTransferCount; //I/O其他操作数据数目；}IO_COUNTERS,*PIO_COUNTERS;以上这些信息应该是比较全面的了，在Win32 API里为我们提供了PSAPI(进程状态)和ToolHelp32这两种探测系统进程/线程信息的方式，在Windows2K/XP/2003都支持它们。 现在，我们来看看系统的性能信息，性能结构SYSTEM_PERFORMANCE_INFORMATION为我们提供了70余种系统性能方面的信息，真是太丰富了，请慢慢体会~
