NAME
Sys::MemInfo - query the total free and used physical memorySYNOPSIS
use Sys::MemInfo qw(totalmem freemem totalswap);
print "total memory: ".(&totalmem / 1024)."\n";
print "free memory: ".(&freemem / 1024)."\n";
print "total swap: ".(&totalswap / 1024)."\n";
print "free swap: ".(Sys::MemInfo::get("freeswap") / 1024)."\n";
DESCRIPTION
Sys::MemInfo return the total amount of free and used physical memory in bytes in totalmem and freemem variables.Total amount of free and user swap memory are alse returned in totalswap and freeswap variables.
This module has been tested on Linux 3.13.0, UnixWare 7.1.2,
AIX5,
OpenBSD 3.8,
NetBSD 2.0.2, FreBSD 5.4, HPUX11,

darwin and Windows XP.
It should work on FreeBSD 4 and Windows 9X/ME/NT/200X/Vista.
METHODS
- availkeys

- freemem
- Returns free physical memory in bytes.
- freeswap
- Returns free swap space in bytes.
- get
- Returns the value of the passed key.
- totalmem
- Returns total physical memory size in bytes.
- totalswap
