本文详细介绍了如何使用UNIX套接字实现服务端和客户端之间的通信，包括套接字创建、绑定、监听、连接、读写操作以及关闭连接的完整流程。

//服务端

#include<sys/types.h>

#include<sys/socket.h>
#include<stdio.h>
#include<sys/un.h>
#include<unistd.h>
#include<stdlib.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");

server_sockfd = socket(AF_UNIX,SOCK_STREAM,0);
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);
while(1){
char ch;
printf("server waiting\n");
client_len = sizeof(client_address);
client_sockfd = accept(server_sockfd,
(struct sockaddr *)&client_address,&client_len);
read(client_sockfd,&ch,1);
ch++;
write(client_sockfd,&ch,1);
close(client_sockfd);
}

}

客户端

#include<sys/types.h>
#include<sys/socket.h>
#include<stdio.h>
#include<sys/un.h>
#include<unistd.h>
#include<stdlib.h>
int main()
{
int sockfd;
int len;
struct sockaddr_un address;
int result;
char ch='A';
sockfd = socket(AF_UNIX,SOCK_STREAM,0);
address.sun_family = AF_UNIX;
strcpy(address.sun_path,"server_socket");
len = sizeof(address);
result = connect(sockfd,(struct sockaddr *)&address,len);
if(result==-1){
perror("oops:client1\n");
exit(1);
}
write(sockfd,&ch,1);
read(sockfd,&ch,1);
printf("char from server = %c\n",ch);
close(sockfd);
exit(0);
}
