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~

}SYSTEM_PERFORMANCE_INFORMATION,*PSYSTEM_PERFORMANCE_INFORMATION;

{
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;

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；
