Re: [Haskell-cafe] Getting used and available memory

Hi I was _not_ looking for the OS-level measure, but rather something reported by the run-time. Thanks you for the answer anyway. /Mads On Tue, 2010-04-27 at 15:32 -0400, Daniel Peebles wrote:

It's not an easy measurement to even define. There was a huge debacle recently about a windows program that reported misleading numbers about used memory. The fact that GHC has its own allocator and "hogs" OS memory (it never returns it to the OS) might complicate the definition further. But in general, if you're looking for an OS-level measure you're probably going to need to go to the FFI and talk to the specific OS's API for the task. I'm not sure if the GHC runtime allows you to ask much about allocated memory. The only thing I've done with it was FFI out to a variable that counts the number of bytes allocated to measure allocations in calls like GHCi does.

I have tried haskell.org, Google and Hoolge, but I cannot find any function to give me the available and/or used memory of a Haskell program. Is it just not there? Or am I missing it somehow?
