NAME

Coro::MakeMaker - MakeMaker glue for the XS-level Coro API

SYNOPSIS

This allows you to control coroutines from C/XS.

DESCRIPTION

For optimal performance, hook into Coro at the C-level. You'll need to make changes to your "Makefile.PL" and add code to your "xs" / "c" file(s).

WARNING

When you hook in at the C-level you can get a huge performance gain, but you also reduce the chances that your code will work unmodified with newer versions of "perl" or "Coro". This may or may not be a problem. Just be aware, and set your expectations accordingly.

HOW TO

Makefile.PL

  use Coro::MakeMaker qw(coro_args);
  # ... set up %args ...
  WriteMakefile (coro_args (%args));

XS

  #include "CoroAPI.h"
  BOOT:
    I_CORO_API ("YourModule");

API

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