NAME

6       Coro::Specific - manage coroutine-specific variables.
7

SYNOPSIS

9        use Coro::Specific;
10
11        my $ref = new Coro::Specific;
12
13        $$ref = 5;
14        print $$ref;
15

DESCRIPTION

17       This module can be used to create variables (or better: references to
18       them) that are specific to the currently executing coroutine. This
19       module does not automatically load the Coro module (so the overhead
20       will be small when no coroutines are used).
21
22       A much faster method is to store extra keys into %$Coro::current - all
23       you have to do is to make sure that the key is unique (e.g. by
24       prefixing it with your module name). You can even store data there
25       before loading the Coro module - when Coro is loaded, the keys stored
26       in %$Coro::current are automatically attached to the coro thread
27       executing the main program.
28
29       You don't have to load "Coro::Specific" manually, it will be loaded
30       automatically when you "use Coro" and call the "new" constructor.
31
32       new Create a new coroutine-specific scalar and return a reference to
33           it. The scalar is guaranteed to be "undef". Once such a scalar has
34           been allocated you cannot deallocate it (yet), so allocate only
35           when you must.
36

BUGS

38       The actual coroutine specific values do not automatically get destroyed
39       when the Coro::Specific object gets destroyed.
