在Ubuntu下实现本地套接字(socket)通信以及遇到的问题！_strcpy(server_addr.sun_path, "server_socket");

客户端：client.c

#include<stdio.h>
#include<sys/socket.h>
#include<sys/types.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");
		exit(1);
	}
 
	write(sockfd,&ch,1);
	read(sockfd,&ch,1);
	printf("char from server = %c \n",ch);
	close(sockfd);
	exit(0);
}

服务端：server.c

#include<stdio.h>
#include<sys/types.h>
#include<sys/socket.h>
#include<sys/un.h>
#include<unistd.h>
 
int m
