Module Name:
|
||
|
|
eldeviceio.h
|
||
|
|
|
||
|
|
Abstract:
|
||
|
|
|
||
|
|
This module contains declarations for media-management and device I/O.
|
||
|
|
The module interfaces with WMI, NDIS for device managment, and NDIS UIO
|
||
|
|
for read/write of data.
|
||
|
|
The routines declared here operate asynchronously on the handles
|
||
|
|
associated with an I/O completion port opened on the ndis uio driver.
