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

CONFIGURATION

This Policy is not configurable except for the standard options.
