NAME

Perl::Critic::Policy::InputOutput::RequireCheckedOpen

DESCRIPTION

The perl builtin I/O function open returns a false value on failure. That value should always be checked to ensure that the open was successful.

  my $error = open( $filehanle, $mode, $filname );                  # ok
  open( $filehanle, $mode, $filname ) or die "unable to open: $!";  # ok
  open( $filehanle, $mode, $filname );                              # not ok
