- call the function specified by the fn argument with an int argument
- indicating the file descriptor, a short argument indicating the type of
- event, and a void * argument given in the arg argument. The fd indicates
- the file descriptor that should be monitored for events. The events can be
- either EV_READ, EV_WRITE, or both. Indicating that an application can read
- or write from the file descriptor respectively without blocking.
-
- The function fn will be called with the file descriptor that triggered the
- event and the type of event which will be either EV_TIMEOUT, EV_SIGNAL,
- EV_READ, or EV_WRITE. The additional flag EV_PERSIST makes an event_add()
- persistent until event_del() has been called.
-
- For read and write events, edge-triggered behavior can be requested
- with the EV_ET flag. Not all backends support edge-triggered
- behavior. When an edge-triggered event is activated, the EV_ET flag
- is added to its events argument.

- a subsequent call to event_base_set() to be safe under many circumstances.
