+AUTOCONF SUPPORT

+ Instead of using EV_STANDALONE=1 and providing your config in whatever
+ way you want, you can also m4_include([libev.m4]) in your configure.ac
+ and leave EV_STANDALONE off. ev.c will then include "config.h" and
+ configure itself accordingly.

PREPROCESSOR SYMBOLS
Libev can be configured via a variety of preprocessor symbols you have to define
- before including any of its files. The default is not to build for mulciplicity

EV_STANDALONE
will also not define any of the structs usually found in "event.h"
that are not directly supported by libev code alone.
- EV_H
-
- The name of the ev.h header file used to include it. The default
- if undefined is <ev.h> in event.h and "ev.h" in ev.c. This can
- be used to virtually rename the ev.h header file in case of
- conflicts.
-
- EV_EVENT_H
-
- Similarly to EV_H, this macro cna be used to override event.c's idea
- of how the event.h header can be found.

EV_USE_MONOTONIC

otherwise another method will be used as fallback. This is the

- EV_COMMON
-
- By default, all watchers have a "void *data" member. By redefining
- this macro to a something else you can include more and other types
- of members. You have to define it each time you include one of the
- files, though, and it must be identical each time.
+ EV_H
- For example, the perl EV module uses this:

+ be used to virtually rename the ev.h header file in case of

- SV *cb_sv, *fh /* note no trailing ";" */
+ EV_EVENT_H
+
+ Similarly to EV_H, this macro cna be used to override event.c's idea
+ of how the event.h header can be found.
EV_PROTOTYPES
event loop pointer argument. Instead, all functions act on the
single default loop.
+ EV_PERIODICS
