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~
typedef struct _SYSTEM_PERFORMANCE_INFORMATION { LARGE_INTEGER IdleTime; //CPU空闲时间； LARGE_INTEGER ReadTransferCount; //I/O读操作数目； LARGE_INTEGER WriteTransferCount; //I/O写操作数目； LARGE_INTEGER OtherTransferCount; //I/O其他操作数目； ULONG ReadOperationCount; //I/O读数据数目； ULONG WriteOperationCount; //I/O写数据数目； ULONG OtherOperationCount; //I/O其他操作数据数目； ULONG AvailablePages; //可获得的页数目； ULONG TotalCommittedPages; //总共提交页数目； ULONG TotalCommitLimit; //已提交页数目； ULONG PeakCommitment; //页提交峰值； ULONG PageFaults; //页故障数目； ULONG WriteCopyFaults; //Copy-On-Write故障数目； ULONG TransitionFaults; //软页故障数目； ULONG Reserved1; ULONG DemandZeroFaults; //需求0故障数； ULONG PagesRead; //读页数目； ULONG PageReadIos; //读页I/O操作数； ULONG Reserved2[2]; ULONG PagefilePagesWritten; //已写页文件页数； ULONG PagefilePageWriteIos; //已写页文件操作数； ULONG MappedFilePagesWritten; //已写映射文件页数； ULONG MappedFileWriteIos; //已写映射文件操作数； ULONG PagedPoolUsage; //分页池使用； ULONG NonPagedPoolUsage; //非分页池使用； ULONG PagedPoolAllocs; //分页池分配情况； ULONG PagedPoolFrees; //分页池释放情况； ULONG NonPagedPoolAllocs; //非分页池分配情况； ULONG NonPagedPoolFress; //非分页池释放情况； ULONG TotalFreeSystemPtes; //系统页表项释放总数； ULONG SystemCodePage; //操作系统代码页数； ULONG TotalSystemDriverPages; //可分页驱动程序页数； ULONG TotalSystemCodePages; //操作系统代码页总数； ULONG SmallNonPagedLookasideListAllocateHits; //小非分页侧视列表分配次数； ULONG SmallPagedLookasideListAllocateHits; //小分页侧视列表分配次数； ULONG Reserved3; ULONG MmSystemCachePage; //系统缓存页数； ULONG PagedPoolPage; //分页池页数； ULONG SystemDriverPage; //可分页驱动页数； ULONG FastReadNoWait; //异步快速读数目； ULONG FastReadWait; //同步快速读数目； ULONG FastReadResourceMiss; //快速读资源冲突数； ULONG FastReadNotPossible; //快速读失败数； ULONG FastMdlReadNoWait; //异步MDL快速读数目； ULONG FastMdlReadWait; //同步MDL快速读数目； ULONG FastMdlReadResourceMiss; //MDL读资源冲突数； ULONG FastMdlReadNotPossible; //MDL读失败数； ULONG MapDataNoWait; //异步映射数据次数； ULONG MapDataWait; //同步映射数据次数； ULONG MapDataNoWaitMiss; //异步映射数据冲突次数； ULONG MapDataWaitMiss; //同步映射数据冲突次数； ULONG PinMappedDataCount; //牵制映射数据数目； ULONG PinReadNoWait; //牵制异步读数目； ULONG PinReadWait; //牵制同步读数目； ULONG PinReadNoWaitMiss; //牵制异步读冲突数目； ULONG PinReadWaitMiss; //牵制同步读冲突数目； ULONG CopyReadNoWait; //异步拷贝读次数； ULONG CopyReadWait; //同步拷贝读次数； ULONG CopyReadNoWaitMiss; //异步拷贝读故障次数； ULONG CopyReadWaitMiss; //同步拷贝读故障次数； ULONG MdlReadNoWait; //异步MDL读次数； ULONG MdlReadWait; //同步MDL读次数； ULONG MdlReadNoWaitMiss; //异步MDL读故障次数； ULONG MdlReadWaitMiss; //同步MDL读故障次数； ULONG ReadAheadIos; //向前读操作数目； ULONG LazyWriteIos; //LAZY写操作数目； ULONG LazyWritePages; //LAZY写页文件数目； ULONG DataFlushes; //缓存刷新次数； ULONG DataPages; //缓存刷新页数； ULONG ContextSwitches; //环境切换数目； ULONG FirstLevelTbFills; //第一层缓冲区填充次数； ULONG SecondLevelTbFills; //第二层缓冲区填充次数； ULONG SystemCall; //系统调用次数； }SYSTEM_PERFORMANCE_INFORMATION,*PSYSTEM_PERFORMANCE_INFORMATION; 现在看到的是结构SYSTEM_PROCESSOR_TIMES提供的系统处理器的使用情况，包括各种情况下的使用时间及中断数目：
typedef struct __SYSTEM_PROCESSOR_TIMES { LARGE_INTEGER IdleTime; //空闲时间； LARGE_INTEGER KernelTime; //内核模式时间； LARGE_INTEGER UserTime; //用户模式时间； LARGE_INTEGER DpcTime; //延迟过程调用时间； LARGE_INTEGER InterruptTime; //中断时间； ULONG InterruptCount; //中断次数； }SYSTEM_PROCESSOR_TIMES,*PSYSTEM_PROCESSOR_TIMES; 页文件的使用情况，SYSTEM_PAGEFILE_INFORMATION提供了所需的相关信息：
typedef struct _SYSTEM_PAGEFILE_INFORMATION { ULONG NetxEntryOffset; //下一个结构的偏移量； ULONG CurrentSize; //当前页文件大小； ULONG TotalUsed; //当前使用的页文件数； ULONG PeakUsed; //当前使用的页文件峰值数； UNICODE_STRING FileName; //页文件的文件名称； }SYSTEM_PAGEFILE_INFORMATION,*PSYSTEM_PAGEFILE_INFORMATION; 系统高速缓存的使用情况参见结构SYSTEM_CACHE_INFORMATION提供的信息：
typedef struct _SYSTEM_CACHE_INFORMATION { ULONG SystemCacheWsSize; //高速缓存大小； ULONG SystemCacheWsPeakSize; //高速缓存峰值大小； ULONG SystemCacheWsFaults; //高速缓存页故障数目； ULONG SystemCacheWsMinimum; //高速缓存最小页大小； ULONG SystemCacheWsMaximum; //高速缓存最大页大小； ULONG TransitionSharedPages; //共享页数目； ULONG TransitionSharedPagesPeak; //共享页峰值数目； ULONG Reserved[2]; }SYSTEM_CACHE_INFORMATION,*PSYSTEM_CACHE_INFORMATION; 1.T-PMList的头文件源代码：
