c++ - 如何实现 WTSRegisterSessionNotification 功能

Question

我想WTSRegisterSessionNotification为我的项目实现功能，现在我被困住了HINSTANCE hInstance;

我想要一个编码示例如何在 C++ 中实现 HINSTANCE

#include <windows.h>
#include <stdio.h>
#include <iostream>
#include <string>
#include "Wtsapi32.h"
#include <tchar.h>

#pragma comment( lib, "user32.lib" )

using namespace std;

static TCHAR szWindowClass[] = _T("win32app");
// The string that appears in the application's title bar.
static TCHAR szTitle[] = _T("Win32 Guided Tour Application");

void main()
{
    // Lock the workstation.
    HWND hWnd = CreateWindow(
        szWindowClass,
        szTitle,
        WS_OVERLAPPEDWINDOW,
        CW_USEDEFAULT, CW_USEDEFAULT,
        500, 100,
        NULL,
        NULL,
        GetModuleHandle(NULL),
        NULL
    );

    cout<< WTSRegisterSessionNotification(hWnd, NOTIFY_FOR_ALL_SESSIONS);;

    if (!LockWorkStation())
    {
        printf("LockWorkStation failed with %d\n", GetLastError());
    }

    cout << WTSRegisterSessionNotification(hWnd, NOTIFY_FOR_ALL_SESSIONS);;

    system("pause");
}

我要实施WTSRegisterSessionNotification(hwnd, NOTIFY_FOR_ALL_SESSIONS);

我收到此错误：

LNK2019 未解析的外部符号 _WTSRegisterSessionNotification@8 在函数 _main 中引用

并找出它返回的值
