创建驱动程序句柄时功能不正确

Question

出于某种原因，当我尝试为驱动程序创建句柄时，我得到incorrect function.（即错误消息1）。这是否意味着我使用错误的函数来创建句柄？我在这里做错了什么？

std::string GetLastErrorAsString()
{
    //Get the error message, if any.
    DWORD errorMessageID = ::GetLastError();
    if(errorMessageID == 0)
        return std::string(); //No error message has been recorded

    LPSTR messageBuffer = nullptr;
    size_t size = FormatMessageA(FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_IGNORE_INSERTS,
                                 NULL, errorMessageID, MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), (LPSTR)&messageBuffer, 0, NULL);

    std::string message(messageBuffer, size);

    //Free the buffer.
    LocalFree(messageBuffer);

    return message;
}


int main()
{
    HANDLE hDriver = CreateFileA("\\\\.\\myDevice", GENERIC_READ | GENERIC_WRITE,
                                  FILE_SHARE_READ | FILE_SHARE_WRITE,
                                  0, OPEN_EXISTING, 0, 0);
    cout << GetLastErrorAsString() << endl;  //"Wrong function"
                                             //hDriver == INVALID_HANDLE_VALUE
    CloseHandle(hDriver);
    return 0;
}
