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.
