How to use HidD_GetHidGuid() in c++?

问题

I've posted a similar topic/question, but this time it's a bit different.

I'm just trying to use the HidD_GetHidGuid() function to get the window's guid for some hid devices, but it's giving me a error LNK2019: unresolved external symbol _HidD_GetHidGuid@4 referenced in function _main

Heres my code:

//mainframe.cpp
#include<iostream>
#include<Windows.h>

extern "C"
{
#include<hidsdi.h>
#include<SetupAPI.h>
}

int main()
{
    int iQuit;
    LPGUID guid;
    HidD_GetHidGuid(guid);

    std::cout << "testing program" << std::endl;
    std::cout << guid << std::endl;


    std::cin >> iQuit;

    return 0;
}

In my VC++ directories I've added C:\WinDDK\7600.16385.1\inc\ddk and C:\WinDDK\7600.16385.1\inc\api to the "include directories". For "Library directories", I have added C:\WinDDK\7600.16385.1\lib

But it's just giving this 1 error, have no idea why... Please help

Thanks

According to the documentation, you need to link against hid.lib

Add this in your header

pragma comment (lib, "hid.lib")
