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

IO::Handle.
