Featured Snippet

Here's a quick look at a common pattern for initializing a WDF driver:


// DriverEntry function for a WDF Kernel-Mode Driver
NTSTATUS
DriverEntry(
    _In_ PDRIVER_OBJECT  DriverObject,
    _In_ PUNICODE_STRING RegistryPath
    )
{
    NTSTATUS status;
    WDF_DRIVER_CONFIG config;

    WDF_DRIVER_CONFIG_INIT(&config, MyEvtDeviceAdd);

    // Create a framework driver object to represent this driver.
    status = WdfDriverCreate(
        DriverObject,
        RegistryPath,
        WDF_NO_OBJECT_ATTRIBUTES,
        &config,
        WDF_NO_HANDLE);

    return status;
}

// EvtDeviceAdd callback for a WDF Kernel-Mode Driver
VOID
MyEvtDeviceAdd(
    _In_ WDFDRIVER Driver,
    _Inout_ PWDFDEVICE_INIT DeviceInit
    )
{
    NTSTATUS status;
    WDFDEVICE hDevice;

    // ... Device Initialization Logic ...

    status = WdfDeviceCreate(&DeviceInit, &deviceAttributes, &hDevice);

    // ... Error Handling ...
}
