Hi all,
I read MSDN artical, BroadcastSystemMessage can send message to installable driver, other legancy drivers and application.
Anyone know how to do that?
In addition, Can I use BroadcastSystemMessage to send and receive message in Ring 0 and Ring 3?
As up today, I still use DeviceIOControl to read/write data.
But if BroadcastSystemMessage could be part of data exchange, that will be great for all.
