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

141 EV_H
142
143 The name of the ev.h header file used to include it. The default
144 if undefined is <ev.h> in event.h and "ev.h" in ev.c. This can
145 be used to virtually rename the ev.h header file in case of
146 conflicts.
147
148 EV_EVENT_H
149
150 Similarly to EV_H, this macro cna be used to override event.c's idea
151 of how the event.h header can be found.
152
153 EV_PROTOTYPES
154
155 If defined to be "0", then "ev.h" will not define any function
156 prototypes, but still define all the structs and other
157 symbols. This is occasionally useful.
158
159 EV_MULTIPLICITY
160
161 If undefined or defined to "1", then all event-loop-specific
162 functions will have the "struct ev_loop *" as first argument, and
163 you can create additional independent event loops. Otherwise there
164 will be no support for multiple event loops and there is no first
165 event loop pointer argument. Instead, all functions act on the
166 single default loop.
167
168 EV_PERIODICS
169
170 If undefined or defined to be "1", then periodic timers are
171 supported, otherwise not. This saves a few kb of code.

151 193 the ev.v header file for their default definitions. One possible
152 EV_MULTIPLICITY 194 use for overriding these is to avoid the ev_loop pointer as first
