No, I am not sure.
When I iterate over all processes, and get the memory for each, together with information like: "is in RAM", "is mapped, but not in RAM", "swapped", "shared with processes a, b, c" then I will be quite content.

Currently I am looking at vm_region_64() from the Kernel.framework.
Others have suggested sysctl(), but the man page is far from complete.
Kind regards,
