	)

Retrieves bus-relative (mainly PCI) hardware resources access ranges and, if possible, claims these resources for the caller.

Parameters

[in]	HwDeviceExtension	The miniport device extension.
[in]	NumRequestedResources	The number of hardware resources in the `RequestedResources` array.
[in]	RequestedResources	An optional array of IO_RESOURCE_DESCRIPTOR elements describing hardware resources the miniport requires.
[in]	NumAccessRanges	The number of ranges in the `AccessRanges` array the miniport expects to retrieve.
[out]	AccessRanges	A pointer to an array of hardware resource ranges VideoPortGetAccessRanges fills with bus-relative device memory ACCESS_RANGE's for the adapter.
[in]	VendorId	For a PCI device, points to a USHORT-type value that identifies the PCI manufacturer of the adapter. Otherwise, should be NULL.
[in]	DeviceId	For a PCI device, points to a USHORT-type value that identifies a particular PCI adapter model, assigned by the manufacturer. Otherwise, should be NULL.
[out]	Slot	Points to a ULONG value that receives the logical slot / location of the adapter (bus-dependent). For a PCI adapter, `Slot` points to a `PCI_SLOT_NUMBER` structure that locates the adapter on the PCI bus.

Returns

NO_ERROR if the resources have been successfully claimed or released.
ERROR_INVALID_PARAMETER if an error or a conflict occurred.
ERROR_DEV_NOT_EXIST if the device is not found.
ERROR_MORE_DATA if there exist more device access ranges available than what is specified by NumAccessRanges.
ERROR_NOT_ENOUGH_MEMORY if there is not enough memory available.
