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.
