I don't know if this is something I am doing wrong or an issue.
When compiling under cygwin sysconf(_SC_PAGESIZE) returns 65536 (64k)
memory page size. My understanding is that:
sysconf(_SC_PAGESIZE) * sysconf(_SC_PHYS_PAGES)
should yield the total physical memory size of the machine. However,
when I do this it yields a very large number (actually overflows my
long). However, if I multiply sysconf(_SC_PHYS_PAGES) * 4096 it yields
the correct size.
My code works properly under linux. Attached is my cygcheck.out.
Thanks,
Ehren

Alas there is a problem with the definition of sysconf: it is supposed to be
the size of the unit of granularity of mmap'ing, but it is also supposed to be
the size of a single pageframe of memory. While it is a correct assumption on
Linux that these things are one and the same, on 'doze you can only mmap pages
in blocks of 64kB, but the pages themselves (the granularity of RWX access
protection rather than of VAD mapping) are the standard 4kB size. This is a
limitation of the underlying windows o/s.
cheers,

_SC_PAGESIZE is only for indicating the page size as used in calls to
mmap(2). POSIX does not demand that _SC_PAGESIZE is actually the
physical page size.
Two quotes from the Linux man pages:
$ man getpagesize
[...]
The function getpagesize() returns the number of bytes in a page,
where a "page" is the thing used where it says in the description of
mmap(2) that files are mapped in page-sized units.
The size of the kind of pages that mmap uses, is found using
#include <unistd.h>
long sz = sysconf(_SC_PAGESIZE);
$ man sysconf
[...]
These values also exist, but may not be standard.
- _SC_PHYS_PAGES
The number of pages of physical memory. Note that it is possi-
ble for the product of this value and the value of
_SC_PAGE_SIZE to overflow.
So, actually Ehren's application works on Linux just coincidentally,
since it make invalid assumptions.
