WdfIoResourceRequirementsListSetSlotNumber function

Description

[Applies to KMDF only]

The WdfIoResourceRequirementsListSetSlotNumber method assigns a slot number to a resource requirements list.

Parameters

RequirementsList [in]

A handle to a framework resource-requirements-list object that represents a device's resource requirements list.

SlotNumber [in]

A value that identifies the bus slot number to which the device is connected.

Remarks

A bug check occurs if the driver supplies an invalid object handle.

Your driver must provide a slot number if your device does not support Plug and Play (PnP).

For more information about resource requirements lists, see Hardware Resources for Framework-Based Drivers.

Examples

The following code example shows how an EvtDeviceResourceRequirementsQuery callback function for a nonPnP device calls WdfIoResourceRequirementsListSetSlotNumber to assign slot 0 to a device.

    IN WDFDEVICE Device,

                                               Requirements,
                                               0
                                               );
