如何在C++中使用LoadLibrary(..)调用kernel32.dll函数GetTickCount()

#include<iostream>
#include<windows.h>

typedef DWORD (WINAPI *GETTICKCOUNT)();

int main() {
    HINSTANCE hDll = LoadLibrary(TEXT("kernel32.dll"));
    if (hDll == NULL) {
        std::cerr << "Failed to load kernel32.dll"<< std::endl;
        return 1;
    }

    GETTICKCOUNT GetTickCountFunc = (GETTICKCOUNT)GetProcAddress(hDll, "GetTickCount");
    if (GetTickCountFunc == NULL) {
        std::cerr << "Failed to get address of GetTickCount"<< std::endl;
        FreeLibrary(hDll);
        return 1;
    }

    DWORD tickCount = GetTickCountFunc();
    std::cout << "GetTickCount: "<< tickCount<< std::endl;

    FreeLibrary(hDll);
    return 0;
}
