Is there a postthread kernel function?

NTDEV

I gpt Walter Oney’s book and I see how to use an event to signal an app an
‘interesting event’ has occured. I can create a thread in my app that sits
in a loop waiting for this event, and when it gets it, it can post a message
to the thread that has my message queue. However, I wanted to know if there
is a way to post to the message queue from the driver itself and save this
step.

I looked but did not find one but since this would be the kernel accessing
smoe structure for the message queue, and not actually passing execution of
the thread, I thought it might be possible.

Thanks,

CT

MsgWaitForMultipleObjects - but read attentively the documentation about its usage …

Kernel driver cannot access the window manager’s message queue.

The best mechanism (provided you will implement cancellation
correctly, as in Walter’s book) - is to send an overlapped IOCTL to
the driver, which will be completed when interesting event occurs.
The advantages are - the cleanest scheme without using any
platform-dependent stuff like object namespace, and the ability of
passing a chunk of information together with the event signaling.
