1.2 Thread control methods

Thread control methods

One thread may explicitely give up CPU to other threads using:

threads->yield;

The thread that created another thread may wait for the child (this operation is blocking unless the child thread is already finished):

$child_thread->join;

Any data that the thread subroutine returns may be accessed in the parent thread:

use threads;

my $child_thread = threads->new(\&my_function);
# ...
my @returned_data = $child_thread->join;
print "Child thread returned @returned_data";

sub my_function { return "Israel PM", 2003, "September", 11; }

The parent thread may also officially stop to worry about the child using:

$child_thread->detach;
