RxTimer.h

Abstract:
|
|||
|
|
|
|||
|
|
This module defines the prototypes and structures for the timer on the rdbss architecture.
|
|||
|
|
What is provided is a 55ms timer...that is, if you register a routine then you get a call
|
|||
|
|
every 55ms. On NT, you're at DPC level.
|
|||
|
|
|
|||
|
|
Also contained here are the routines for posting to a thread from DPC level.
