The below output file, generated by your code is not enough to clarify you?

Your code without the sleep()'s:

#! perl -slw use strict; use Time::HiRes qw[ time sleep ]; use threads; use threads::shared; our $THREADS ||= 4; my $sem :shared; open LOG, '>', 'log.txt' or die $!; sub logit { lock $sem; return printf LOG @_; } sub thread { my $tid = threads->self->tid; my $stop = shift; warn $tid, ": starting:", time(), " Stoptime: $stop\n"; while( time() < $stop ) { logit "%2d: The time is %f\n", $tid, time; } warn $tid, ": stopping at ", time(), "\n"; } my @threads = map threads->create( \&thread, time() + int( rand 10 ) ), 1 .. $THREADS; warn "threads started; waiting\n"; $_->join for @threads; warn "threads done\n"; open LOG, '<', 'log.txt' or die $!; print while <LOG>; close LOG;

My position in this forum is to share ideas,opinions,knowledge,... and of course, "to learn", with the help of all the monks. And only joining strengths it will be possible to achieve real knowledge. Sometimes this forum is used to humiliate members in order to praise to himself, which is a pity.

A contentious debate is always associated with a lack of valid arguments.
