NAME

File::Policy::Default - Default policy for file I/O functions

SYNOPSIS

         use File::Policy;
         use File::Policy qw/check_safe/;   # to import a specific subroutine
         use File::Policy qw/:all/;         # to import all subroutines
 
         #Checking I/O policy
         check_safe($filename, 'r');
         check_safe($filename, 'w');
 
         #Portable directory locations
         $logdir = get_log_dir();
         $tmpdir = get_temp_dir();

DESCRIPTION

This defines the default (unrestricted) policy for file I/O with modules such as File::Slurp::WithinPolicy. You may replace this default policy with one for your organisation.
