#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.
