File::Policy::Default - Default policy for file I/O functions
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();
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.
check_safe( FILENAME , MODE );
Checks a filename is safe - dies if not. MODE is r (read) or w (write). Default is no restrictions on file I/O.
$temporary_directory = get_temp_dir();
Returns the path to temporary directory from the TEMP environment variable or File::Spec::Functions::tmpdir(). Note that any return value will have been cleared of a trailing slash.
$log_directory = get_log_dir();
Returns the path to log directory from the LOGDIR environment variable or the current directory. Note that any return value will have been cleared of a trailing slash.
