=head1 NAME |
| 39 |
|
| 40 |
EV::MakeMaker - MakeMaker glue for the C-level EV API |
| 41 |
|
| 42 |
=head1 SYNOPSIS |
| 43 |
|
| 44 |
This allows you to access some libevent functionality from other perl |
| 45 |
modules. |
| 46 |
|
| 47 |
=head1 DESCRIPTION |
| 48 |
|
| 49 |
For optimal performance, hook into EV at the C-level. You'll need |
| 50 |
to make changes to your C<Makefile.PL> and add code to your C<xs> / |
| 51 |
C<c> file(s). |
| 52 |
|
| 53 |
=head1 HOW TO |
| 54 |
|
| 55 |
=head2 Makefile.PL |
| 56 |
|
| 57 |
use EV::MakeMaker qw(ev_args); |
| 58 |
|
| 59 |
# ... set up %args ... |
| 60 |
|
| 61 |
WriteMakefile (ev_args (%args)); |
| 62 |
|
| 63 |
=head2 XS |
| 64 |
|
| 65 |
#include "EVAPI.h" |
| 66 |
|
| 67 |
BOOT: |
| 68 |
I_EV_API ("YourModule"); |
| 69 |
|
| 70 |
=head1 API |
| 71 |
|
| 72 |
See the L<EVAPI.h|http://cvs.schmorp.de/EV/EV/EVAPI.h> header. |
| 73 |
|
| 74 |
In short, all the functions and macros from F<ev.h> should work, except |
| 75 |
that the trailing underscore macros (C<EV_A_>, C<EV_DEFAULT_>) are not |
| 76 |
available (except C<EV_P_> :). |
| 77 |
|
| 78 |
Multiplicity is enabled. |
| 79 |
|
| 80 |
The C<data> member in each watcher is of type C<SV *> and not C<void *> |
| 81 |
(this might change at some point). |
| 82 |
|
| 83 |
=head1 EXAMPLE |
| 84 |
|
| 85 |
The L<EV::Glib>, L<EV::ADNS> and L<Glib::EV> all give nice examples on how |
| 86 |
to use this module. |
| 87 |
|
| 88 |
Here are some F<.xs> fragments taken from EV::ADNS that should get you |
| 89 |
going: |
| 90 |
|
| 91 |
#include "EVAPI.h" |
| 92 |
|
| 93 |
static ev_prepare pw; |
| 94 |
static ev_idle iw; |
| 95 |
|
| 96 |
static void |
| 97 |
idle_cb (EV_P_ ev_idle *w, int revents) |
| 98 |
{ |
| 99 |
ev_idle_stop (EV_A, w); |
| 100 |
} |
| 101 |
|
| 102 |
MODULE = ... |
| 103 |

BOOT: |

| 106 |
I_EV_API ("EV::ADNS"); |
| 107 |
ev_prepare_init (&pw, prepare_cb); |
| 108 |
ev_init (&iw, idle_cb); ev_set_priority (&iw, EV_MINPRI); |
| 109 |
ev_idle_start (EV_DEFAULT, &iw); |
