linux 下第一个Libevent代码学习

1 #include <event.h>
  2 struct event ev;
  3 struct timeval tv;
  4 
  5 void time_cb(int fd, short event, void* argc)
  6 {
  7         printf("timer wakeup\n");
  8         event_add(&ev, &tv);
  9 }
 10 
 11 int main()
 12 {
 13         struct event_base*base = event_init();
 14         tv.tv_sec = 10;
 15         tv.tv_usec = 0;
 16         evtimer_set(&ev, time_cb, NULL);
 17         event_add(&ev, &tv);
 18         event_base_dispatch(base);
 19         return 0;
 20 }

注意编译的时候gcc -o * *.c -levent

需要加上-levent链接库
