client.c~

已经通过调试的socket客服端程序 对于初学者写linux程序很有帮助哟

#include<stdio.h>
#include<string.h>
#include<stdlib.h>
#include<sys/socket.h>
#include<sys/types.h>
#include<netdb.h>
#include<netinet/in.h>
int main(void)
{
  
  int client_socket;
  struct sockaddr_in sever_addr; 

  char rec[100];

  bzero(&sever_addr,sizeof(struct sockaddr_in));
  sever_addr.sin_family=AF_INET;
  sever_addr.sin_addr.s_addr=inet_addr("192.168.0.23");
  sever_addr.sin_port=htons(7000);
 
  if((client_socket=socket(AF_INET,SOCK_STREAM,0))==-1)
   {
     printf("socket is error!\n");
     exit(1);
   }
   
  if(connect(client_socket,(struct sockaddr*)(&sever_addr),sizeof(struct sockaddr))==-1)
   {
     printf("client connect is error!\n");
     exit(1);
   }
   
  read(client_socket,rec,100,0);
  printf("%s\n",rec); 
  printf("receive from server is successful!\n");
  
  write(client_socket,"this is client send",strlen("this is client send")+1,0);
  
  printf("send data to server is successful!\n");
  
  close(client_socket);
   
}
