NdisRawWritePortBufferUlong

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

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

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.

Requirements

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.
