EV::MakeMaker(3) User Contributed Perl Documentation EV::MakeMaker(3)NAMEEV::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" and add code to your "xs" / "c"
file(s).
HOW TO
Makefile.PL
use EV::MakeMakerqw(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);
}
