我是驱动程序开发的新手。这是我的代码：

#include <ndis.h>
#include <fwpmk.h>
#include <fwpvi.h>
#include <fwpsk.h>
#include <fstream.h>
#pragma comment(lib, "libcpmtd.lib")

extern "C" {

    NTSTATUS DriverEntry(
        _In_ struct _DRIVER_OBJECT *DriverObject,
        _In_ PUNICODE_STRING       RegistryPath
    )
    {
        ofstream s("D:\\somefile.txt");
        s << "driver initialized.";
        return 0;
    }
}

产生以下错误列表：

这个符号（ios，ofstream） - 来自 msvcrt.dll（或者即使使用静态 libc - 例如它具有来自 kernel32.dll 的依赖项）并且不能在内核模式下使用。您需要删除“ostream s”- 使用 DbgPrint 或 ZwCreateFile/ZwWriteFile 进行日志记录
