NdisRawWritePortUchar

This function writes a byte to an I/O port on the NIC.

At a Glance

Header file: Ndis.h
Windows CE versions: 2.0 and later

Syntax

VOID NdisRawWritePortUchar( IN ULONG Port, IN UCHAR Data );

Parameters

Port
Specifies the I/O port. This address falls in a range that was mapped during initialization with the NdisMRegisterIoPortRange function.
Data
Specifies the byte to be written.

Remarks

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

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