Sommaire

NAME

Perl::Critic::Policy::InputOutput::RequireCheckedClose - Write "my $error = close $fh;" instead of "close $fh;".

AFFILIATION

This Policy is part of the core Perl::Critic distribution.

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

CONFIGURATION

This Policy is not configurable except for the standard options.
