How to determine the number of threads?

[Manikanta]

Hi,

I have an application coded in C++ using Linux. How can i know the number of threads in my application? How can i know how many instances of each thread are being created?

Thanks & Regards,

You can run "top" and use the "?" to select the username your process/threadds is running. Top will show you the number and what each thread status is.

Hope this helps.

well, since you're using c++, you can easily manage all threads and actually just count them using RAII. Keep in mind C++ doesn't have a standard about threads, so you'll either have to dive into pthreads or "emulate" counting using, like i said, RAII or something ilke that.

actually just count them using RAII

I would have said, "actually just count them using an integer". ;)

But if you want to go with RAII and that term is unfamiliar to you, go here.

don't worry, i know what i'm talking about. yes, an integer is needed. but if you put every thread inside a class, and make that class destroy when the thread exits, you can use RAII to easily atomically increase and decrease that integer. sounds like a very good OOP design to me

Hi,

Thanks for the reply. Can u send me the correct syntax of TOP to be used to find the instances of each thread being created?
