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

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", load "EV" in your "pm" file 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));

   extension.pm
         use EV (); # imports optional

   extension.xs
         #include "EVAPI.h"

         [...]

         BOOT:
           I_EV_API (HvNAME (GvSTASH (CvGV (cv))));

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);
         }
