NAME

DESCRIPTION

9       The perl builtin I/O function "open" returns a false value on failure.
10       That value should always be checked to ensure that the open was suc‐
11       cessful.
12
13         my $error = open( $filehanle, $mode, $filname );                  # ok
14         open( $filehanle, $mode, $filname ) or die "unable to open: $!";  # ok
15         open( $filehanle, $mode, $filname );                              # not ok
