Perl::Critic::Policy::InputOutput::RequireCheckedOpen - Write my $error = open $fh, $mode, $filename;
instead of open $fh, $mode, $filename;
.
This Policy is part of the core Perl::Critic distribution.
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( $filehandle, $mode, $filename ); # ok open( $filehandle, $mode, $filename ) or die "unable to open: $!"; # ok open( $filehandle, $mode, $filename ); # not ok
This Policy is not configurable except for the standard options.
