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.
