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.

152 EV_PROTOTYPES
153
154 If defined to be "0", then "ev.h" will not define any function
155 prototypes, but still define all the structs and other
156 symbols. This is occasionally useful.

158 EV_MULTIPLICITY
159
160 If undefined or defined to "1", then all event-loop-specific
161 functions will have the "struct ev_loop *" as first argument, and
162 you can create additional independent event loops. Otherwise there
163 will be no support for multiple event loops and there is no first
164 event loop pointer argument. Instead, all functions act on the
165 single default loop.

167 EV_PERIODICS

169 If undefined or defined to be "1", then periodic timers are
170 supported, otherwise not. This saves a few kb of code.
