NSLog 10b meaning?

I am new to objc and iOS development. And, I have a question about NSLog. As we know, NSLog will log message like this:

2011-07-16 23:19:35.467 HelloWorld[11166:7c37] say hello to iOS.

Obviously the format is date time ProjectName, but what does the [11166:7c37] part mean?

have a look to : [NSLog 10b meaning?](http://stackoverflow.com/questions/1428544/nslog-10b-meaning) — , Jul 16 '11 at 15:32
Nice observation; but what you want to achieve by knowing this? — Waqas Raja, Jul 16 '11 at 15:34
@Waqas Raja: it is apparently output for a reason, so it is, IMO, legitimite to ask what that reason is. — Rudy Velthuis, Jul 16 '11 at 15:36
Just looked to the post, of course it's process id and thread id! Thank you! — Tony, Jul 16 '11 at 15:38
@Waqas Raja I just want to know what it is, because I think it should be some useful message if it is putted there by default. — Tony, Jul 16 '11 at 15:41
