[python-win32] How to calc amount of avail RAM in a process ?

[Steven James]

Agreed, but PDH can give per-process statistics, too. For high-memory-usage
apps, I would think that it would be nice for your app to know whether it is
*likely* to need to swap out (by comparing needed memory to availably
physical memory).
Anyway, using the same API, you can determine how much memory space your own
app is currently using, which was the original question. Probably clunky,
but as I said, I'm not an expert.
like so.....
