memoru usage of process

[Jacek Pop³awski]

I need to know how much memory uses child process (after
subprocess.Popen), so I want function:

get_memory_usage(pid)

I found two ways:

- call "ps" and analyze its output - this is not portable (different
output on Linux, Cygwin and QNX)

- use resource.getrusage - but it works for self/children, not for
single process with given pid

Do you know any ideas how to do it in Python?

On Linux, this may work for you

Yes, I have seen it in archive, but I was searching for Python way, and
it's not Python related at all (it is just reading system file), and
won't work on QNX.

What do you mean by 'Python way' and 'not related to Python'?

How is parsing the output of 'ps' different from the method used in
recipe 286222?
