NDIS drivers call the NdisMSetBusData function to write to the configuration space of a device.

Syntax

ULONG NdisMSetBusData(
       IN NDIS_HANDLE NdisMiniportHandle,
  [in] IN ULONG       WhichSpace,
  [in] IN ULONG       Offset,
  [in] IN PVOID       Buffer,
  [in] IN ULONG       Length
);

Parameters

NdisMiniportHandle

The miniport adapter handle that NDIS passed to the MiniportAdapterHandle parameter of the MiniportInitializeEx function.

[in] WhichSpace

The type of bus data to be written. For further information, see the discussion of the WhichSpace parameter on the reference page for IRP_MN_READ_CONFIG.

[in] Offset

The byte offset in the configuration space, specified by WhichSpace, to which data is written.

[in] Buffer

A pointer to a buffer that contains the data to write to the bus. Must be at least as large as Length .
