在应用层调用ZwQueryInformationThread失败，求大神帮忙

//下面是一部分代码
//头文件
#include <windows.h>

#include <psapi.h>
#include <TLHELP32.H>

//还有这些声明
#pragma comment(lib,"psapi.lib")
typedef enum _THREADINFOCLASS {
ThreadBasicInformation,
ThreadTimes,
ThreadPriority,
ThreadBasePriority,
ThreadAffinityMask,
ThreadImpersonationToken,
ThreadDescriptorTableEntry,

} THREADINFOCLASS;


extern "C"
LONG
(__stdcall *ZwQueryInformationThread)( HANDLE ThreadHandle,
THREADINFOCLASS ThreadInformationClass,
PVOID ThreadInformation,
ULONG ThreadInformationLength,
PULONG ReturnLength) = NULL;

typedef struct _CLIENT_ID
{
HANDLE UniqueProcess;
HANDLE UniqueThread;
} CLIENT_ID;

typedef CLIENT_ID *PCLIENT_ID;

typedef struct _THREAD_BASIC_INFORMATION
{
LONG ExitStatus;
PVOID TebBaseAddress;
CLIENT_ID ClientId;
LONG AffinityMask;
LONG Priority;

}THREAD_BASIC_INFORMATION,*PTHREAD_BASIC_INFORMATION;
//

//下面是调用部分，我调试时发现 ZwQueryInformationThread 的地址为NULL，然后就报错
HANDLE hThread = OpenThread(THREAD_QUERY_INFORMATION,FALSE,dwThreadId);

THREAD_BASIC_INFORMATION tbi;

ZwQueryInformationThread(hThread,ThreadBasicInformation,&tbi,sizeof(THREAD_BASIC_INFORMATION),0);


//求帮帮助

ZwQueryInformationThread这个函数老是不识别啊。到底怎么回事呢？
