Coro::MakeMaker - MakeMaker glue for the XS-level Coro API |
44 |
root |
1.1 |
|
45 |
|
|
=head1 SYNOPSIS |
46 |
|
|
|
47 |
root |
1.19 |
This allows you to control coroutines from C/XS. |
48 |
root |
1.1 |
|
49 |
|
|
=head1 DESCRIPTION |
50 |
|
|
|
51 |
root |
1.19 |
For optimal performance, hook into Coro at the C-level. You'll need to |
52 |
|
|
make changes to your C<Makefile.PL> and add code to your C<xs> / C<c> |
53 |
|
|
file(s). |
54 |
root |
1.1 |
|
55 |
|
|
=head1 WARNING |
56 |
|
|
|
57 |
root |
1.19 |
When you hook in at the C-level you can get a I<huge> performance gain, |
58 |
|
|
but you also reduce the chances that your code will work unmodified with |
59 |
|
|
newer versions of C<perl> or C<Coro>. This may or may not be a problem. |
60 |
|
|
Just be aware, and set your expectations accordingly. |

This is just a small overview - read the Coro/CoroAPI.h header file in |
82 |
|
|
the distribution, and check the examples in F<EV/> and F<Event/*>, or |
83 |
|
|
as a more real-world example, the Deliantra game server (which uses |
84 |
|
|
Coro::MakeMaker). |
