/*
client.c
*/
#include <sys/types.h>
#include <sys/socket.h>
#include <stdio.h>
#include <sys/un.h>
#include <unistd.h>
int main()
{
int sockfd;
int len;
struct sockaddr_un address;
int result;
char ch=A;   //A好像有问题，改为ch了。。。编译通过。
sockfd=socket(AF_UNIX,SOCK_STREAM,0);
/*以上建立客户端的套接口,采用AF_UNIX的unix域协议*/
address.sun_family=AF_UNIX;
strcpy(address.sun_path,"server_socket");
len=sizeof(address);
/*以上创建服务器套接口的地址,其中包括套接口类型,名称*/
result=connect(sockfd,(struct sockaddr *)&address,len);

if(result==-1){
perror("oops:client1");
exit(1);

}
/*以上我们试图与服务器套接口建立连接*/
write(sockfd,&ch,1);
read(sockfd,&ch,1);
/*如果成功,将向服务器端发送一个字符,然后读取服务器的回答*/

printf("char from server=%c\n",ch);
close(sockfd);
exit(0);
}

/*
server.c
*/
#include <sys/types.h>
#include <sys/socket.h>
#include <stdio.h>
#include <sys/un.h>
#include <unistd.h>
int main()
{
int server_sockfd,client_sockfd;
int server_len,client_len;
struct sockaddr_un server_address;
struct sockaddr_un client_address;
unlink("server_socket");
/*如果存在同名的套接口,则先删除*/
server_sockfd=socket(AF_UNIX,SOCK_STREAM,0);
/*以上建立套接口,这时候无名*/
server_address.sun_family=AF_UNIX;
strcpy(server_address.sun_path,"server_socket");
server_len=sizeof(server_address);
bind(server_sockfd,(struct sockaddr *)&server_address,server_len);

listen(server_sockfd,5);
/*以上创建监听队列.等待用户的连接请求*/
while(1)
{
char ch;
printf("server waiting\n");
client_sockfd=accept(server_sockfd,(struct sockaddr *)&client_address,&client_len);
/*以上接受一个客户的请求*/
read(client_sockfd,&ch,1);
/*因为连接一旦建立,客户就会先发消息过来,所以服务器先读*/
ch++;
write(client_sockfd,&ch,1);
/*把读取的字符串做简单处理,回送*/
close(client_sockfd);
}
}
