KernelIoControl编译错误

BUILD: [01:0000000052:ERRORE] Restart.obj : error LNK2019: unresolved external symbol "int __cdecl KernelIoControl(unsigned long,void *,unsigned long,void *,unsigned long,unsigned long *)"

    重启：KernelIoControl(IOCTL_HAL_REBOOT, NULL, 0, NULL, 0, NULL);
    关机：SetSystemPowerState(NULL, POWER_STATE_OFF, POWER_FORCE);
    待机：GwesPowerOffSystem();

#include <windows.h>#include "winioctl.h"BOOL KernelIoControl(DWORD dwIoControlCode, LPVOID lpInBuf, DWORD nInBufSize,                               LPVOID lpOutBuf, DWORD nOutBufSize, LPDWORD lpBytesReturned);#define IOCTL_HAL_GET_DEVICE_INFO CTL_CODE(FILE_DEVICE_HAL, 1, METHOD_BUFFERED, FILE_ANY_ACCESS)#define IOCTL_HAL_REBOOT          CTL_CODE(FILE_DEVICE_HAL, 15, METHOD_BUFFERED, FILE_ANY_ACCESS)#define IOCTL_HAL_COLDBOOT        CTL_CODE(FILE_DEVICE_HAL, 30, METHOD_BUFFERED, FILE_ANY_ACCESS)

void WINAPI Reboot (int nBootMode){    int   inVal;    BYTE  outBuf[1024];    DWORD bytesReturned;   //KernelIoControl(IOCTL_HAL_REBOOT, NULL, 0, NULL, 0, NULL)

    if(nBootMode == 0)        KernelIoControl(IOCTL_HAL_REBOOT, &inVal, 4, outBuf, 1024, &bytesReturned);   //热启动    else        KernelIoControl(IOCTL_HAL_COLDBOOT, &inVal, 4, outBuf, 1024, &bytesReturned); //冷启动}

在PB工程里编译会出现错误，需加上头文件:extern "C" __declspec(dllimport)

extern "C" __declspec(dllimport)BOOL KernelIoControl( DWORD dwIoControlCode, LPVOID lpInBuf, DWORD nInBufSize, LPVOID lpOutBuf, DWORD nOutBufSize, LPDWORD lpBytesReturned);
extern "C" __declspec(dllimport)BOOL InterruptInitialize(   DWORD idInt,   HANDLE hEvent,   LPVOID pvData,   DWORD cbData );
