NdisRawWritePortBufferUlong

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

Syntax

VOID NdisRawWritePortBufferUlong( IN ULONG Port,
IN PULONG Buffer, IN ULONG Length );

Parameters

Port: Specifies the I/O port. This address falls in a range that was mapped during initialization with the NdisMRegisterIoPortRange function.
Buffer: Pointer to a caller-allocated resident buffer containing the ULONGs to be written.
Length: Specifies the number of ULONGs to write to the I/O port.

Remarks

An NIC driver calls this function to transfer a sequence of ULONGs, one at a time, to its NIC.

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

A driver that calls this function can run at any IRQL.
