NAME

Perl::Critic::Policy::InputOutput::RequireCheckedClose

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
