Note NDIS 5. x has been deprecated and is superseded by NDIS 6. x. For new NDIS driver development, see Network Drivers Starting with Windows Vista. For information about porting NDIS 5. x drivers to NDIS 6. x, see Porting NDIS 5.x Drivers to NDIS 6.0.

NdisWritePortBufferUlong is called by the miniport driver to write ULONGs from a buffer to a NIC.

Syntax

VOID NdisWritePortBufferUlong(
  _In_ NDIS_HANDLE NdisAdapterHandle,
  _In_ ULONG       Port,
  _In_ PULONG      Buffer,
  _In_ ULONG       Length
);

Parameters

NdisAdapterHandle [in]
Specifies the handle that the NDIS interface library associates with the network interface card.
Port [in]
Specifies the I/O port.
Buffer [in]
Pointer to the caller-supplied buffer from which this function writes the ULONG values to Port.
Length [in]
Specifies the number of ULONGs to write to Port.

Return value

None

Remarks

NdisWritePortBufferUlong sequentially writes each ULONG to the port. It determines how the host accesses the I/O port and processes the write request accordingly.
