get number of threads from a running process

[Skellington]

Hello,
is it possible to get a count on the number of threads a process is
using? For example lets say I have Apache "httpd" and it has 66
threads running according to top. Is there a way to get the number
using ruby?

Thanks,
Charlie

On Linux

def thread_count(pid)
Dir["/proc/#{pid}/task/*"].size
end

Kind regards
