C++第四十一篇 -- 安装成功的第一个驱动文件

参考连接：https://blog.csdn.net/LEON1741/article/details/87291839

1、新建工程

2、写一个Driver.c

#include <ntddk.h>
#include <wdf.h>

DRIVER_INITIALIZE DriverEntry;
EVT_WDF_DRIVER_DEVICE_ADD KmdfHelloWorldEvtDeviceAdd;

NTSTATUS
DriverEntry(
    _In_ PDRIVER_OBJECT     DriverObject,
    _In_ PUNICODE_STRING    RegistryPath
)
{
    // NTSTATUS variable to record success or failure
    NTSTATUS status = STATUS_SUCCESS;

    // Allocate the driver configuration object
    WDF_DRIVER_CONFIG config;

    // Print "Hello World" for DriverEntry
    KdPrintEx((DPFLTR_IHVDRIVER_ID, DPFLTR_INFO_LEVEL, "KmdfHelloWorld: DriverEntry\n"));

    // Initialize the driver configuration object to register the
    // entry point for the EvtDeviceAdd callback, KmdfHelloWorldEvtDeviceAdd
    WDF_DRIVER_CONFIG_INIT(&config,
        KmdfHelloWorldEvtDeviceAdd
    );

    // Finally, create the driver object
    status = WdfDriverCreate(DriverObject,
        RegistryPath,
        WDF_NO_OBJECT_ATTRIBUTES,
        &config,
        WDF_NO_HANDLE
    );
    return status;
}

NTSTATUS
KmdfHelloWorldEvtDeviceAdd(
    _In_    WDFDRIVER       Driver,
    _Inout_ PWDFDEVICE_INIT DeviceInit
)
{
    // We're not using the driver object,
    // so we need to mark it as unreferenced
    UNREFERENCED_PARAMETER(Driver);

    NTSTATUS status;

    // Allocate the device object
    WDFDEVICE hDevice;

    // Print "Hello World"
    KdPrintEx((DPFLTR_IHVDRIVER_ID, DPFLTR_INFO_LEVEL, "KmdfHelloWorld: KmdfHelloWorldEvtDeviceAdd\n"));

    // Create the device object
    status = WdfDeviceCreate(&DeviceInit,
        WDF_NO_OBJECT_ATTRIBUTES,
        &hDevice
    );
    return status;
}

3、配置项目

4、编译

 

编译出来的文件放在

 

如此驱动文件就完成了。

 

接下来须要将它安装到虚拟机上了。以前文章中有写一个msi的文件，须要在虚拟机上安装，而后虚拟机要是测试模式，安装驱动能够经过devcon也能够本身手动安装，在设备管理器里。记住调试的时候要下断点。若是Win10上面显示不出KdPrintEx的话，能够调注册表，调试方法都在调试的那篇文章里。
