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 |
|

|
|

|
|
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. |

|
157 | |
|
|

|
|
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. |
|
|
166 | |
|
|
167 | EV_PERIODICS |
|
|
168 | |
|
|
169 | If undefined or defined to be "1", then periodic timers are |
|

170 | supported, otherwise not. This saves a few kb of code. |
