thanks for your reply. I means in my project, I want to use NSTask
to launch an application, and send application some parameters, when
use NSTask launch application that will add a new thread, right?
As far as I understand, you use NSTask to launch your application. But
this does not imply that a new thread is created to monitor the
launched process, unless of course, if you setup your own thread to
monitor the process.
So I think you assume that NSTask will use a thread but this is wrong.
NSTask is just a wrapper around execve(), no threading involved here.
and then send Apple event, when application received Apple event ,
it will quit, usually, the thread starts by NSTask will exit,
because the application had quit, so I don't understand this, if use
NSTask launch application more times, thread count will always
increased, even if application had quit. I appreciate that any
reply, thank you very much.
You can use ThreadViewer to convince yourself that there's no
threading involved by using NSTask.

was no problem on tiger, just present leopard. Sorry for my poor
english.
I assume that "AP" acually means "application".
I understand that you send some Apple event to your application
like a "quit' event, right?
You say that your application exit. OK. So what process the threads
you're talking about belong to?
Where does NSTask come into this?
You have to be more precise to get an answer...
