NdisMPciAssignResources

This function returns a list of bus-relative hardware resources, such as IRQ, I/O ports, and device memory ranges, claimed in the registry for a PCI NIC.

At a Glance

Header file:	Ndis.h
Windows CE versions:	2.0 and later

Syntax

NDIS_STATUS NdisMPciAssignResources(
IN NDIS_HANDLE MiniportHandle, IN ULONG SlotNumber,
OUT PNDIS_RESOURCE_LIST *AssignedResources );

Parameters

MiniportHandle: Specifies the MiniportAdapterHandle passed in to the MiniportInitialize function and to most other MiniportXXX functions.
SlotNumber: Specifies the slot number of the driver’s NIC on the PCI bus.
AssignedResources: Pointer to a list of the hardware resources the NIC can use.

Return Values

Returns NDIS_STATUS_SUCCESS.

Remarks

This function claims a set of hardware resources in the registry for a miniport’s PCI NIC to use, thus preventing conflicting claims on the same resources from other devices in the machine.

The buffer specified at AssignedResources is formatted as an NDIS_RESOURCE_LIST structure, which is equivalent to the CM_PARTIAL_RESOURCE_LIST structure on Windows NT platforms.

The bus-relative configuration parameters returned in this buffer can be used in the MiniportInitialize function’s subsequent calls to NdisXXX functions such as NdisMRegisterInterrupt, NdisMMapIoSpace, and/or NdisMRegisterIoPortRange.

A driver that calls this function runs at IRQL PASSIVE_LEVEL.
