Event_base a collection of similar events, you create an event and you must specify a collection for the event.

struct Event_base {
The const struct EVENTOP *evsel; /*evsel and Evbase on the relationship between the analogy and the class and the object, Evbase is Evsel
511 specific implementations, referring to the reuse model used here */
*evbase void;
53/* The number of events that this event_base is concerned with */
Event_count int; /* counts number of total events * *
55/* Number of active events in this event_base */
event_count_active int; /* counts number of active events */
57/* Determine the condition of the loop exit */
Event_gotterm int; /* Set to terminate loop */
Event_break int; /* Set to terminate loop immediately */

*/* Active Event Management */
62/* Save the event chain list, execute the chain with different priority events, so use level two pointers to activate the list of events */
Event_list **activequeues;
