skynet网络库socket-server

最近在读大神云风的开源服务器架构skynet，其中的网络库，云风已经单独开来，可以独立使用。

开源地址：

网络库已经封装了socket的epoll.

在下载起来的世里面，已经包含了一个例子，但觉得不够明了。于是自己写了个测试例子，分为服务端了客户端，服务端启动并监听端口，客户端启动并连接服务器，向服务器发送消息，并得到服务器的反馈。

服务端代码：

#include "socket_server.h"

#include <pthread.h>
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <signal.h>

static void *
_poll(void * ud) {
    struct socket_server *ss = ud;
    struct socket_message result;
    for (;;) {
        int type = socket_server_poll(ss, &result, NULL);
        // DO NOT use any ctrl command (socket_server_close , etc. ) in this thread.
        switch (type) {
        case SOCKET_EXIT:
            return NULL;
        case SOCKET_DATA:
            printf("message(%lu) [id=%d] size=%d  %s\n",result.opaque,result.id, result.ud, result.data);
            // free(result.data);
            socket_server_send(ss, result.id, result.data, result.ud) ;
            break;
        case SOCKET_CLOSE:
            printf("close(%lu) [id=%d]\n",result.opaque,result.id);
            break;
        case SOCKET_OPEN:
            printf("open(%lu) [id=%d] %s\n",result.opaque,result.id,result.data);
            break;
        case SOCKET_ERROR:
            printf("error(%lu) [id=%d]\n",result.opaque,result.id);
            break;
        case SOCKET_ACCEPT:
            printf("accept(%lu) [id=%d %s] from [%d]\n",result.opaque, result.ud, result.data, result.id);
            socket_server_start(ss,201,result.ud);
            break;
        }
    }
}

static void
test(struct socket_server *ss) {
    pthread_t pid;
    pthread_create(&pid, NULL, _poll, ss);

    // int c = socket_server_connect(ss,100,"127.0.0.1",80);
    // printf("connecting %d\n",c);
    int l = socket_server_listen(ss,200,"127.0.0.1",8888,32);
    printf("listening %d\n",l);
    socket_server_start(ss,201,l);
    // int b = socket_server_bind(ss,300,1);
    // printf("binding stdin %d\n",b);
    // int i;
    // for (i=0;i<100;i++) {
    //     socket_server_connect(ss, 400+i, "127.0.0.1", 8888);
    // }
    // sleep(5);
    // socket_server_exit(ss);

    pthread_join(pid, NULL); 
}

int
main() {
    struct sigaction sa;
    sa.sa_handler = SIG_IGN;
    sigaction(SIGPIPE, &sa, 0);

    struct socket_server * ss = socket_server_create();
    test(ss);
    // socket_server_release(ss);

    return 0;
