KdPrintEx(( DPFLTR_IHVDRIVER_ID, DPFLTR_INFO_LEVEL, "KmdfHelloWorld: DriverEntry\n" )) Allocate the driver configuration object NTSTATUS variable to record success or failure Use the following code to write your DriverEntry: NTSTATUS Next, provide declarations for the two callbacks you'll use: DRIVER_INITIALIZE DriverEntry ĮVT_WDF_DRIVER_DEVICE_ADD KmdfHelloWorldEvtDeviceAdd Ntddk.h contains core Windows kernel definitions for all drivers, while Wdf.h contains definitions for drivers based on the Windows Driver Framework (WDF). If you can't add Ntddk.h, open Configuration -> C/C++ -> General -> Additional Include Directories and add C:\Program Files (x86)\Windows Kits\10\Include\\km, replacing with the appropriate directory in your WDK installation. In the Add New Item dialog box, select C++ File. In the Solution Explorer window, again select and hold (or right-click) the KmdfHelloWorld project, choose Add, and then select New Item.

You can see them in the Solution Explorer window. Visual Studio creates one project and a solution. In the Location field, enter the directory where you want to create the new project.Ĭheck Place solution and project in the same directory and select Create. This length limit is defined in wdfglobals.h. When you create a new KMDF or UMDF driver, you must select a driver name that has 32 characters or less.
