Perl::Critic::Policy::InputOutput::RequireCheckedClose - Write my $error = close $fh; instead of close $fh; .
Perl::Critic::Policy::InputOutput::RequireCheckedClose - Write
my $error = close $fh;
This Policy is part of the core Perl::Critic distribution.
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
If you create a module that exports
autodie you can tell this policy about it with the
[InputOutput::RequireCheckedSyscalls] autodie_modules = My::Thing
