Ahem, "pinned" is not "shared". It is just that most of the standard applications which use pinned memory (foremost Oracle DB) also use shared memory segments to a large extent. Therefore i took an "educated guess" that maybe the presence of pinned memory hints at such a software being used. Why they do it that way? Ask Oracle! I just administrate machines running their product.
I hope this helps.

getopt::usaginator
Getopt::Usaginator(3pm) User Contributed Perl Documentation Getopt::Usaginator(3pm)
NAME
Getopt::Usaginator - Conjure up a usage function for your applications
VERSION
version 0.0012
SYNOPSIS
use Getopt::Usaginator <<_END_;
Usage: xyzzy <options>
--derp Derp derp derp
--durp Durp durp durp
-h, --help This usage
_END_
# The 'usage' subroutine is now installed
...
$options = parse_options( @ARGV ); # Not supplied by Usaginator
usage if $options{help}; # Print usage and exit with status 0
if ( ! $options{derp} ) {
# Print warning and usage and exit with status -1
usage "You should really derp";
}
if ( $options{durp} ) {
# Print warning and usage and exit with status 2
usage 2 => "--durp is not ready yet";
}
...
usage 3 # Print usage and exit with status 3
DESCRIPTION
Getopt::Usaginator is a tool for creating a handy usage subroutine for commandline applications
It does not do any option parsing, but is best paired with Getopt::Long or any of the other myriad of option parsers
USAGE
use Getopt::Usaginator <usage>
Install a "usage" subroutine configured with the <usage> text
$code = Getopt::Usaginator->usaginator( <usage> )
Return a subroutine configured with the <usage> text
...
More advanced usage is possible, peek under the hood for more information
perldoc -m Getopt::Usaginator
An example:
use Getopt::Usaginator
# Called with the error
error => sub { ... },
# Called when usage printing is needed
usage => sub { ... },
...
;
An example with Getopt::Long parsing
use Getopt::Usaginator ...
sub run {
my $self = shift;
my @arguments = @_;
usage 0 unless @arguments;
my ( $help );
{
local @ARGV = @arguments;
GetOptions(
'help|h|?' => $help,
);
}
usage 0 if $help;
...
}
