libevent使用

1.安装libevent
安装libebent省略
2.使用libevent高性能io框架库

#include 
#include 

void signal_cb(int fd, short event, void* argc)
{
    struct event_base* base = (event_base*) argc;
    struct timeval delay = {2,0};
    printf("caught an interrupt signal; exiting cleanly in two seconds...\n");
    event_base_loopexit(base, &delay);
}

void timeout_cb(int fd, short evvent, void* argc)
{
    printf("timeout\n");
}

int main()
{
    struct event_base* base = event_init();

    struct event* signal_event = evsignal_new(base, SIGINT, signal_cb, base);
    event_add(signal_event, NULL);

    timeval tv = {1,0};
    struct event* timeout_event = evtimer_new(base, timeout_cb, NULL);
    event_add(timeout_event, &tv);

    event_base_dispatch(base);

    event_free(timeout_event);
    event_free(signal_event);
    event_base_free(base);

    return 0;
}
