=head1 NAME |
| 39 |
|
| 40 |
Coro::MakeMaker - MakeMaker glue for the C-level Coro API |
| 41 |
|
| 42 |
=head1 SYNOPSIS |
| 43 |
|
| 44 |
This allows you to control coroutines from C level. |
| 45 |
|
| 46 |
=head1 DESCRIPTION |
| 47 |
|
| 48 |
For optimal performance, hook into Coro at the C-level. You'll need |
| 49 |
to make changes to your C<Makefile.PL> and add code to your C<xs> / |
| 50 |
C<c> file(s). |
| 51 |
|
| 52 |
=head1 WARNING |
| 53 |
|
| 54 |
When you hook in at the C-level you get a I<huge> performance gain, |
| 55 |
but you also reduce the chances that your code will work unmodified |
| 56 |
with newer versions of C<perl> or C<Coro>. This may or may not be a |
| 57 |
problem. Just be aware, and set your expectations accordingly. |
| 58 |
