_In_ PVOID  VendorId,

)

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

Parameters
[in]HwDeviceExtensionThe miniport device extension.
[in]NumRequestedResourcesThe number of hardware resources in the RequestedResources array.
[in]RequestedResourcesAn optional array of IO_RESOURCE_DESCRIPTOR elements describing hardware resources the miniport requires.
[in]NumAccessRangesThe number of ranges in the AccessRanges array the miniport expects to retrieve.
[out]AccessRangesA pointer to an array of hardware resource ranges VideoPortGetAccessRanges fills with bus-relative device memory ACCESS_RANGE's for the adapter.
[in]VendorIdFor a PCI device, points to a USHORT-type value that identifies the PCI manufacturer of the adapter. Otherwise, should be NULL.
[in]DeviceIdFor 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]SlotPoints 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.
