Examples

The following code example shows how an EvtDeviceResourceRequirementsQuery callback function creates an empty logical configuration and appends it to a resource requirements list.

NTSTATUS
Example_EvtDeviceResourceRequirementsQuery(
    IN WDFDEVICE Device,
    IN WDFIORESREQLIST RequirementsList
    )
{
    NTSTATUS  status;
    WDFIORESLIST  logConfig;

    status = WdfIoResourceListCreate(
                                     RequirementsList,
                                     WDF_NO_OBJECT_ATTRIBUTES,
                                     &logConfig
                                     );
    if (!NT_SUCCESS(status)) {
        return status;
    }

    status = WdfIoResourceRequirementsListAppendIoResList(
                                             RequirementsList,
                                             logConfig
                                             );
    if (!NT_SUCCESS(status)) {
        return status;
    }
...
}
