Perl::Critic::Policy::InputOutput::ProhibitOneArgSelect(3)
NAME
Perl::Critic::Policy::InputOutput::ProhibitOneArgSelect - Never write
"select($fh)".
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
Conway discourages the use of a raw "select()" when setting
autoflushes. We'll extend that further by simply prohibiting the one-
argument form of "select()" entirely; if you really need it you should
know when/where/why that is. For performing autoflushes, Conway
recommends the use of "IO::Handle" instead.
select((select($fh), $|=1)[0]); # not ok
select $fh; # not ok
use IO::Handle;
$fh->autoflush(); # ok
*STDOUT->autoflush(); # ok
CONFIGURATION
This Policy is not configurable except for the standard options.
SEE ALSO
