6 Perl::Critic::Policy::InputOutput::RequireCheckedOpen - Write "my
7 $error = open $fh, $mode, $filename;" instead of "open $fh, $mode,
8 $filename;".

11 This Policy is part of the core Perl::Critic distribution.
12
14 The perl builtin I/O function "open" returns a false value on failure.
15 That value should always be checked to ensure that the open was
16 successful.
17
18 my $error = open( $filehandle, $mode, $filename ); # ok
19 open( $filehandle, $mode, $filename ) or die "unable to open: $!"; # ok
20 open( $filehandle, $mode, $filename ); # not ok
21
22 use autodie;
23 open $filehandle, $mode, $filename; # ok
24
25 You can use autodie, Fatal, or Fatal::Exception to get around this.
26 Currently, autodie is not properly treated as a pragma; its lexical
27 effects aren't taken into account.
28
30 This Policy is not configurable except for the standard options.
