NdisWritePortBufferUchar (NDIS 5.1) function

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 x has been deprecated and is superseded by NDIS 6.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.

NdisWritePortBufferUchar is called by the NIC driver to write UCHARs from a buffer to its NIC.

Syntax

VOID NdisWritePortBufferUchar(
  _In_ NDIS_HANDLE NdisAdapterHandle,
  _In_ ULONG       Port,
  _In_ PUCHAR      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 UCHAR values to Port.

• Length [in]
  Specifies the number of UCHARs to write to Port.

Return value

None

Remarks

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