KeybdPdd_PowerHandler
This function is called by the MDD on system power state changes.

Syntax
void WINAPI KeybdPdd_PowerHandler( BOOL bOff );

Parameters
bOff
Boolean. TRUE indicates the system is being turned off. FALSE indicates the system is being turned on.
Remarks
This function runs in kernel context and assumes that interrupts are disabled because it works directly with CPU registers. It does not make any system calls or cause tasks to be rescheduled in any way. This function is restricted to reading and writing to pre-allocated memory. Any subroutines called from this function must follow this restriction.

This function supports the implementation of the Keyboard Driver PDD.

        VC/MFC社区版块或许是CSDN最“古老”的版块了,记忆之中,与CSDN的年龄几乎差不多。随着时间的推移,MFC技术渐渐的偏离了开发主流,若干年之后的今天,当我们面对着微软的这个经典之笔,内心充满着敬意,那些曾经的记忆,可以说代表着二十年前曾经的辉煌……
        向经典致敬,或许是老一代程序员内心里面难以释怀的感受。互联网大行其道的今天,我们期待着MFC技术能够恢复其曾经的辉煌,或许这个期待会永远成为一种“梦想”,或许一切皆有可能……
