WdfIoResourceRequirementsListSetSlotNumber function (wdfresource.h)

[Applies to KMDF only]

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

Syntax

VOID WdfIoResourceRequirementsListSetSlotNumber(
 [in] WDFIORESREQLIST RequirementsList,
 [in] ULONG SlotNumber
);

Parameters

[in] RequirementsList

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

[in] SlotNumber

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

Return value

None

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.

NTSTATUS
Example_EvtDeviceResourceRequirementsQuery(
 IN WDFDEVICE Device,
 IN WDFIORESREQLIST Requirements
 )
{
...
 WdfIoResourceRequirementsListSetSlotNumber(
 Requirements,
 0
 );
...
}
