Perl::Critic::Policy::InputOutpUserPConPerl::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
       IO::Handle.
