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

140 EV_H
141
142 The name of the ev.h header file used to include it. The default
143 if undefined is <ev.h> in event.h and "ev.h" in ev.c. This can
144 be used to virtually rename the ev.h header file in case of
145 conflicts.
146
147 EV_EVENT_H
148
149 Similarly to EV_H, this macro cna be used to override event.c's idea
150 of how the event.h header can be found.

184 Can be used to change the callback member declaration in each
185 watcher, and the way callbacks are invoked and set. Must expand
186 to a struct member definition and a statement, respectively. See
187 the ev.v header file for their default definitions. One possible
188 use for overriding these is to avoid the ev_loop pointer as first
189 argument in all cases, or to use method calls instead of plain
190 function calls in C++.
