44 threads - Perl extension allowing use of interpreter based threads from perl

71 Perl 5.6 introduced something called interpreter threads. Interpreter
72 threads are different from "5005threads" (the thread model of Perl
73 5.005) by creating a new perl interpreter per thread and not sharing
74 any data or state between threads.
76 Prior to perl 5.8 this has only been available to people embedding
77 perl and for emulating fork() on windows.
79 The threads API is loosely based on the old Thread.pm API. It is very
80 important to note that variables are not shared between threads, all
81 variables are per default thread local. To use shared variables one
82 must use threads::shared.
84 It is also important to note that you preferably enable threads by
85 doing C<use threads> as early as possible and that it is not possible
86 to enable threading inside an eval "";
90 =item $thread = new(function, LIST)
92 This will create a new thread with the entry point function and give
93 it LIST as parameters. It will return the corresponding threads
96 create() is an alias to new.
100 This will wait for the corresponding thread to join. When it finishes
101 join will return the return values of the entry point function. If a
102 thread has been detached, join will return without wait.
104 =item $thread->detach
106 Will throw away the return value from the thread and make it
111 This will return the object for the current thread.
115 This will return the id of the thread. threads->self->tid() is a
116 quick way to get current thread id.
125 =item Fix so the return value is returned when you join.
129 =item Fix memory leaks!
