Question

以下代码是TCP客户端的套接字编程示例。

但是当我运行它时，connect（）被重新调整为协议不支持的地址族。我正在尝试通过套接字进行服务器客户端通信。首先我们向客户端发送一些字符串，然后我们从客户端读取一些字符串并打印出来。

#include<stdio.h>
#include<sys/types.h>
#include<sys/socket.h>
#include<sys/un.h>
#define ADDRESS     "mysocket"
char *str[3]={"dfgff","trer","ytt"};
int main()
{
char c;
FILE *fp;
register int i,s,ns,len;
int fromlen;
struct sockaddr saun,fsaun;
if((s=socket(AF_UNIX,SOCK_STREAM,0))<0)
{
perror("server:socket");
exit(1);
}


  unlink("mysocket");

    if (bind(s,&saun,sizeof(saun))<0)
    {
        perror("server: bind");
        exit(1);
    }
if (listen(s, 5) < 0)
    {
        perror("server: listen");
        exit(1);
    }

    if ((ns = accept(s, &fsaun, NULL)) < 0)
    {
        perror("server: accept");
        exit(1);
    }
 fdopen(ns, "r");

    /*
     * First we send some strings to the client.

    for (i = 0; i <3 ; i++)
        send(ns, str[i], strlen(str[i]), 0);

    /*
     * Then we read some strings from the client and
     * print them out.
     */
    for (i = 0; i <3; i++)
    {
        while ((c = fgetc(fp)) != EOF)
        {
            putchar(c);

            if (c == '\n')
                break;
        }
    }
close(s);
exit(0);
return 0;
}

connect（）中协议不支持的地址族
