Re: Concurrent execution of threads

[kcott]

G'day pplshlp,

// introduces a comment in a number of languages but not in Perl. You need a # in Perl.

With your code, I get:

Bareword found where operator expected at -e line 20, near "//do somet
+hing"
    (Missing operator before something?)
syntax error at -e line 21, near "//do something
"

Changing //do something to #do something, I get:

Starting main program
End of main program

I don't see a concurrency issue:

$ perl -e '
use strict;
use warnings;
use threads;
use threads::shared;

print "Started at: ", time, "\n";
print "Starting main program\n";

my @threads;
for ( my $count = 1; $count <= 10;$count++) {
        my $t = threads->new(\&sub1);
        push(@threads,$t);
}
foreach (@threads) {
        $_->join;
}
print "End of main program\n";
print "Stopped at: ", time, "\n";

sub sub1 {
        print "Called at: ", time, "\n";
        sleep 2;
        #do something
}
