Getting system memory isn't part of any standard that I know of (at least on 
the posix side), and there's not a large demand for it.  The API for getting 
memory is decided on by OS implementors.  What you would end up with is a 
list of versions for not only different OSes, but different versions of the 
OS.  It's along the same lines as getting/setting network interface 
addresses.
