NdisRawWritePortBufferUshort

  • Artigo

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

VOID NdisRawWritePortBufferUshort(
IN ULONG Port, 
IN PUSHORT 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 USHORTs to be written.
  • Length
    Specifies the number of USHORTs to write to the I/O port.

Remarks

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

This function runs significantly faster than the NdisImmediateWritePortBufferUshort 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.

Requirements

Runs on Versions Defined in Include Link to
Windows CE OS 2.0 and later Ndis.h    

Note   This API is part of the complete Windows CE OS package as provided by Microsoft. The functionality of a particular platform is determined by the original equipment manufacturer (OEM) and some devices may not support this API.
