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 x has been deprecated and is superseded by NDIS 6.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

NdisRawWritePortBufferUlong writes a specified number of ULONG values from a caller-supplied buffer to a given I/O port.

Syntax


VOID NdisRawWritePortBufferUlong(
  _In_ ULONG_PTR Port,
  _In_ PULONG    Buffer,
  _In_ ULONG     Length
);

Parameters

Port [in]

Specifies the I/O port. This address falls in a range that was mapped during initialization with NdisMRegisterIoPortRange.

Buffer [in]

Pointer to a caller-allocated resident buffer containing the ULONGs to be written.

Length [in]

Specifies the number of ULONGs to write to the I/O port.

Return value

None

Remarks

A NIC driver calls NdisRawWritePortBufferUlong to transfer a sequence of ULONGs, one at a time, to its NIC.

NdisRawWritePortBufferUlong runs significantly faster than NdisImmediateWritePortBufferUlong because it need not map a bus-relative port address onto a host-dependent logical port address at every call.

Requirements

Target platform

Desktop
