It is important to understand that "POSIX compliant" invariably means
"POSIX superset", since many significant functions are not part of the
current POSIX standard, 1003.1.  There is no POSIX `getsysinfo' call.
The closest you get is `sysconf()', which can be used to ask about a
few things like the maximum number of open files.  None of the things
you mention are in the list.

Correct.  In any case, it is typically not a very useful piece of
information, since there is no simple correlation between the size of
physical memory and how much your program is allowed to use.
