Windows, NT Object Manager

preview
Posted by The Channel 9 Team // Wed, Dec 7, 2005 5:37 PM

Almost everything you do on your PC requires the assistance of NT's Object Manager. The Object Manager is a shared resource; a subsystem upon which all other executive kernel subsystems rely on to get their jobs done. That said, among NT's kernel components, the OM receives the least amount of attention. Well, not anymore. Charles has a brief chat with Adrian Marinescu, a senior developer who works on the Object Manager as well as LPC and the Heap Manager.

Oh my. What a wonderful face! The emoticon in the post is HUGE, and the text is to tiny to read. Going to watch the video anyway.

That was really weird... here's what it looked like:

The image “http://www.geocities.com/mvaneerde/smiley.jpg” cannot be displayed, because it contains errors.

And here's the offending code:

I'd agree that the OM receives very little attention(wrongfully so). But the "LPC facility" receives barely any. Microsoft barely acknowledges its existence. Please have a video on that....I'd really like to hear something about it other than "It's there"



PS- really good job on the videos so far. they are really enjoyable.

Yeah, a video about the various IPC mechanisms available in the kernel (I know about two: LPC and Lightweigth LPC(or is it Fast LPC?)) would be interesting. And isn't there some new IPC coming in Longhorn, btw?

I have a pretty in-depth overview of the Object Manager on my blog...quite similar to Adrian's video, but a bit more "hard substance" (actual structures are shown)..although not as generic. A good read if you're interested in the Ob.

Great explanation.
I would love to see second episode of the Objcet Manager and to get more explanation about how specific components are relate to the Object Manager. For example the Windows Handles, Process Handles.

Great show.

Ido.
