                                           User Contributed Perl Documentation


NAME
       Perl::Critic::Policy::BuiltinFunctions::ProhibitSleepViaSelect - Use
       Time::HiRes instead of something like "select(undef, undef, undef,
       .05)".

AFFILIATION
       This Policy is part of the core Perl::Critic distribution.

DESCRIPTION
       Conway discourages the use of select() for performing non-integer
       sleeps.  Although documented in perlfunc, it's something that generally
       requires the reader to read "perldoc -f select" to figure out what it
       should be doing.  Instead, Conway recommends that you use the
       "Time::HiRes" module when you want to sleep.

           select undef, undef, undef, 0.25;         # not ok

           use Time::HiRes;
           sleep( 0.25 );                            # ok

CONFIGURATION
       This Policy is not configurable except for the standard options.

SEE ALSO
       Time::HiRes.
