Perl::Critic::Policy::InputOutput::RequireCheckedClose(3User Contributed Perl DocumentatiPerl::Critic::Policy::InputOutput::RequireCheckedClose(3)
NAME
Perl::Critic::Policy::InputOutput::RequireCheckedClose - Write "my $error = close $fh;" instead of "close $fh;".
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
The perl builtin I/O function "close" returns a false value on failure. That value should be checked to ensure that the close was
successful.
my $error = close $filehandle; # ok
close $filehandle or die "unable to close: $!"; # ok
close $filehandle; # not ok
use autodie qw< :io >;
close $filehandle; # ok
You can use autodie, Fatal, or Fatal::Exception to get around this. Currently, autodie is not properly treated as a pragma; its lexical
effects aren't taken into account.
CONFIGURATION
This Policy is not configurable except for the standard options.
