data type limitation

I am writing some code to do analysis on the file system (HP-UX 11.11). I am using stat(..) to get file information. My problem is that the file-size may exceed the data types defined in 'sys/stat.h' & 'sys/types.h' respectively. Thus file-sizes in the Giga-byte range are not read correctly....

NAME

       Paranoid::Data - Misc. Data Manipulation Functions

VERSION

       $Id: Data.pm,v 0.02 2010/04/15 23:23:28 acorliss Exp $

SYNOPSIS

	   $rv = deepCopy($sourceRef, $targetRef);

DESCRIPTION

       This module provides data manipulation functions, which at this time only consists of deepCopy.

SUBROUTINES
/METHODS
   deepCopy
	   $rv = deepCopy($sourceRef, $targetRef);

       This function performs a deep and safe copy of arbitrary data structures, checking for circular references along the way.  Hashes and lists
       are safely duplicated while all other data types are just copied.  This means that any embedded object references, etc., are identical in
       both the source and the target, which is probably not what you want.

       In short, this should only be used on pure hash/list/scalar value data structures.  Both the source and the target reference must be of an
       identical type.

       This function returns the number of elements copied unless it runs into a problem (such as a circular reference), in which case it returns
       a zero.
