NAME

6       EV::MakeMaker - MakeMaker glue for the C-level EV API
7

SYNOPSIS

9       This allows you to access some libevent functionality from other perl
10       modules.
11

DESCRIPTION

13       For optimal performance, hook into EV at the C-level.  You'll need to
14       make changes to your "Makefile.PL", load "EV" in your "pm" file and add
15       code to your "xs" / "c" file(s).
16

HOW TO

18   Makefile.PL
19         use EV::MakeMaker qw(ev_args);
20
21         # ... set up %args ...
22
23         WriteMakefile (ev_args (%args));
24
25   extension.pm
26         use EV (); # imports optional
27
28   extension.xs
29         #include "EVAPI.h"
30
31         [...]
32
33         BOOT:
34           I_EV_API (HvNAME (GvSTASH (CvGV (cv))));
35

API

37       See the EVAPI.h <http://cvs.schmorp.de/EV/EV/EVAPI.h> header, which you
38       should include instead of ev.h.
39
40       In short, all the functions and macros from ev.h should work, except
41       that the trailing underscore macros ("EV_A_", "EV_DEFAULT_") are not
42       available (except "EV_P_" :).
43
44       Multiplicity is enabled.
45
46       The "data" member in each watcher is of type "SV *" and not "void *"
47       (this might change at some point).
48

EXAMPLE

50       The EV::Glib, EV::ADNS and Glib::EV modules all give nice examples on
51       how to use this module.
52
53       Here are some .xs fragments taken from EV::ADNS that should get you
54       going:
55
56         #include "EVAPI.h"
57
58         static ev_prepare pw;
59         static ev_idle iw;
60
61         static void
62         idle_cb (EV_P_ ev_idle *w, int revents)
63         {
64           ev_idle_stop (EV_A, w);
65         }
66
67         MODULE = ...
68
69         BOOT:
70         {
71           I_EV_API ("EV::ADNS");
72           ev_prepare_init (&pw, prepare_cb);
73           ev_init (&iw, idle_cb); ev_set_priority (&iw, EV_MINPRI);
74           ev_idle_start (EV_DEFAULT, &iw);
75         }
