libevent使用

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

#include <sys/signal.h>#include <event.h>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;}

3.运行
