Proc::ProcessTable has access to the sort of information found in programs like top and ps. This sub finds the memory usage of the program that calls it.

Proc::ProcessTable currently works on windows, linux, solaris, aix, hpux, freebsd, irix, dec_osf, bsdi, netbsd, unixware 7.x and SunOS.

The windows port requires the Cygwin environment. 

use Proc::ProcessTable;
print "My memory=", memory_usage(), "\n";

sub memory_usage {
  my $t = new Proc::ProcessTable;
  foreach my $got ( @{$t->table} ) {
    next if not $got->pid eq $$;
    return $got->size;
  }
}
