NAME

EV::MakeMaker - MakeMaker glue for the C-level EV API

CONTENTS

SYNOPSIS

This allows you to access some libevent functionality from other perl modules.

DESCRIPTION

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

HOW TO

    Makefile.PL



  use EV::MakeMaker qw(ev_args);

  # ... set up %args ...

  WriteMakefile (ev_args (%args));



    XS



  #include "EVAPI.h"

  BOOT:
    I_EV_API ("YourModule");



API

See the EVAPI.h <http://cvs.schmorp.de/EV/EV/EVAPI.h> header, which you should include instead of ev.h.

In short, all the functions and macros from ev.h should work, except that the trailing underscore macros (EV_A_, EV_DEFAULT_) are not available (except EV_P_ :).

Multiplicity is enabled.

The data member in each watcher is of type SV * and not void * (this might change at some point).

EXAMPLE

The EV::Glib, EV::ADNS and Glib::EV modules all give nice examples on how to use this module.

Here are some .xs fragments taken from EV::ADNS that should get you going:



  #include "EVAPI.h"

  static ev_prepare pw;
  static ev_idle iw;

  static void
  idle_cb (EV_P_ ev_idle *w, int revents)
  {
    ev_idle_stop (EV_A, w);
  }

  MODULE = ...

  BOOT:
  {
    I_EV_API ("EV::ADNS");
    ev_prepare_init (&pw, prepare_cb);
    ev_init (&iw, idle_cb); ev_set_priority (&iw, EV_MINPRI);
    ev_idle_start (EV_DEFAULT, &iw);
  }
