话说那NT也有历遍进程的函数,那就是PSAPI.函数为:
BOOL EnumProcesses(
DWORD *lpidProcess, // array of process identifiers
DWORD cb, // size of array
DWORD *cbNeeded // number of bytes returned
);
和
BOOL EnumProcessModules(
HANDLE hProcess, // handle to process
HMODULE *lphModule, // array of module handles
DWORD cb, // size of array
LPDWORD lpcbNeeded // number of bytes required
);
前一函数返回所有进程的ID.而后一函数根据进程句柄来获取该进程的模块句柄数组.这里介绍的乃是另外一种方法.该方法比上述方法速度快很多.就是运用NATIVE API.下面乃是公开的秘密.:)网络上已经有很多关于此函数的论述,该函数查询功能之大,超乎想象,几乎任何系统信息都可以查询,现在披露有关历遍进程的部分.:)

NTSYSAPI
NTSTATUS
NTAPI
NtQuerySystemInformation(
IN SYSTEMINFOCLASS SystemInfoClass, //Set to 5 for enumerate all process
OUT PVOID SystemInfoBuffer,
IN ULONG SystemInfoBufferSize,
OUT PULONG BytesReturned OPTIONAL
);
当然,KMD也可以在PASSIVE LEVEL运用此函数的内核引出:
NTSYSAPI
NTSTATUS
NTAPI
ZwQuerySystemInformation(
IN SYSTEMINFOCLASS SystemInfoClass, //Set to 5 for enumerate all process
OUT PVOID SystemInfoBuffer,
IN ULONG SystemInfoBufferSize,
OUT PULONG BytesReturned OPTIONAL
);
妙极否?:)由于查询功能太过强大,此函数必须有SE_TCB_NAME特权才能运作.大家感受到了SE_TCB_NAME特权的吸引人之处了吧!:DDD特权特权我所爱也.;)))

用PSAPI，给你源码，有点乱，慢慢看吧。
