NAME

Devel::Size - Perl extension for finding the memory usage of perl variables

SYNOPSIS

use Devel::Size qw(size);
$size = size("abcde");
$other_size = size(\@foo);

DESCRIPTION

This module figures out the real sizes of perl variables. Call it with a reference to the variable you want the size of. If you pass in a plain scalar it returns the size of that scalar. (Just be careful if you're asking for the size of a reference, as it'll follow the reference if you don't reference it first)

EXPORT

None by default.

BUGS

Only does plain scalars, hashes, and arrays. No sizes for globs or code refs. Yet.

Also, this module currently only returns the size used by the variable itself, not the contents of arrays or hashes, nor does it follow references past one level. That's for later.
